1. The request shall be made 12 hours prior to
the estimated time of commencement of thepilotage.
2. The request shall be made to the
Association’s joint office by letter, telephone,or other secure methods.
3. When making the application for pilotage inthe preceding paragraph, the following items
shall be notified; the vessel name, tonnage,
length, draft, the presence of appropriate
multi deck boats, the name or the appellation
and address of the ship owner (Article 3 of
the Pilotage Law), the presence ofappropriate export exemption (consumptiontax), speed, type of cargo, scheduled pilotage
start date, pilot period, necessity ofquarantine, and other required items.
4. Pilot boarding facilities in accordance with
the IMO requirements and IMPA
recommendation shall be provided on the
opposite side of wind waves or swell.

1. During strong winds, particularly in winter,high waves often prevent a pilot fromboarding outside the breakwater. In this casea pilot boat (tugboat) waits the vessel near
the port entrance of the N end of W
Breakwater, and boards while the vessel isproceeding on inbound course. The pilot
ladder shall be rigged on the port side.
2. When the weather worsens, vessel intending
to enter the port shall be sure to contact
Rumoi Coast Guard or the ship’s agent for
information on weather, oceanographic
conditions, etc.
Inbound vessels are recommended to wait fora pilot in the quarantine anchorage.

PRECAUTIONSNavigational Precautions

Standards for nautical charts etc. In order to prevent marine accidents, the Japan Coast Guard is giving
the following guideline which includes standards for necessary nautical charts to be carried onboard.
1. Necessary charts for safe navigation should be on board.
Vessels navigating in the seas around Japan are to keep charts covering the areas to be navigated.
Nautical publications, such as “Sailing Directions”, “Tide Tables”, “Chart Showing the Positions ofPart 1

20

GENERAL INFORMATION

Set Net Fisheries”, are also to be kept on board to understand the situations of the areas where thevessel intends to navigate.
Classification of the scheduled navigation area
Areas beyond the limit of Japanese territorial sea(Restricted to approaches to Japanese territorial sea)
Territorial sea of Japan
Areas subject to the Port Regulations Law

Charts required for safe navigation
Charts of a scale larger than 1/500,000
Charts of a scale larger than 1/250,000
Charts of the largest scale for the planned navigation
areas

Prior study(1) In preparing a voyage plan, areas where the vessel is going to navigate should be sufficiently studied
utilizing charts, Sailing Directions, etc.
(2) Maritime traffic statutes and guidelines, such as the Law for Preventing Collision at Sea, Maritime
Traffic Safety Law and Port Regulations Law, applicable to such areas should be fully understood andcomplied with.
(3) Course lines, information on clearing lines for avoiding obstructions, etc. should be indicated oncharts in advance.
3. Proper use of charts(1) Charts should be kept up-to-date in accordance with the Notices to Mariners.
(2) If charts and a satellite navigation system like GPS are used at the same time, geodetic systems
should be unified.
(3) Charts with a proper scale corresponding to areas to be navigated should be used, and such chartsshould be kept ready for use during navigation.
Sheltering. When a typhoon or a strong extratropical cyclone approaches, it is recommended that shelterbe taken in a suitable harbour at an early stage. However, considering that cases may arise where vessels may
be obliged to change the sheltering place depending upon the conditions there, sheltering shall be made by
day before the weather worsens.
Geographical conditions on the S coast of Hokkaido are favorable for shelter avoiding strong W winds inwinter. Vessels shall be cautious in taking shelter in the E, N and W coasts, where swell and waves havedirect influence on vessels. Further details of sheltering places are described in Part 3 “COASTAL ROUTESAND HARBOURS.”
Navigation in fog. A vessel navigating in fog should pay attention to the following points as well as
observing the regulations of the Law for Preventing Collisions at Sea.
1. Reduce its speed, place extra lookouts (arrange at bow and height if necessary), maintain a safe courseand pay attention to other vessels.
2. Make the appropriate fog signals.
3. Avoid other vessels with sufficient clearance when detected by the radar.
Precautions to be taken in an ice field navigation.
1. The watch posted on a mast is the key lookout and adviser. Identifying relatively thin ice or gaps in theice, is the best way to make a passage through ice. The lookout up the mast watch will get used to
identifying such areas by observing shapes and colors and reporting the same to the bridge.
2. The distribution and movement of ice may be assessed by radar watch from the change with times in
the radar responses depending upon prevailing conditions.
3. When a vessel such as an icebreaker navigates in ice bound seas, seals in herds can occasionally be
spotted on ice, which invariably indicates the existence of thin ice or clearance in ice in theChapter 7

neighborhood. This case can be utilized as one of ways to select a vessel’s course.
4. Vessels which navigate in ice bound seas inevitably suffer hull damage, especially to propeller blades
which tend to receive damage from ice blocks sent down by eddy currents caused by astern engine
motions. Furthermore, even if a large block of ice is fragmentized by the inertial movement of a vessel,
the vessel tends to suffer damages to her shell plating and others unless the hull has a special
construction.
Ice accumulation on the hull. There is a danger of ice accumulating on the hull and structures of avessel resulting in marine disasters such as capsizing and, thus, mariners must be cautious.
1. Ice accumulation may occur when sea water spray or sea water breaking over the vessel with the airtemperature below -3 °C and relative wind speed 8 m/s or more. The accumulation becomes serious withthe air temperature below -6 °C and relative wind speed 10 m/s or more.
2. As to the water temperature, ice accumulation was formally thought not to occur with a surface seatemperature of 5 °C or more, but there were cases where accumulation has occurred in areas 13 to 14 °C
in seawater temperature. Thus, it can be assumed that ice accumulation does not have direct connection
with the sea temperature.
3. When a vessel navigates in an area where there is a risk of ice accumulation on the hull, the vessel
shall adjust the course and speed to avoid the accumulation and when ice has begun to build up, earlyremoval must be done.
Prediction of Ice accumulation. A method to predict ice accumulation on the hull is introduced below
by utilizing an analysis chart of 850 hPa at a height of 1,500 m released from Hakodate Local Meteorological
Office.
Generally ice accumulation on the hull occurs at sea when temperatures of -15 °C or lower at the 850 hPa
isobaric surfaces are experienced. Especially severe accumulation is seen beneath the cold air mass, -18 °C or
lower at that level. Accordingly vessels shall first examine the 850 hPa analysis chart facsimiled from theJapan Meteorological Agency whether a cold air mass exists in their way and if it is expected to enter areas
beneath the air mass of -15 °C or lower in temperature, vessels shall prepare in advance for the removal of
possible ice accumulation and try to avoid entering areas beneath the air mass of -18 °C as far as possible.
Reference Matters. When navigating areas where drift ice may be encountered, matters to be referred toin predicting the approach of drift ice are described below.
1. 1st Regional Coast Guard Headquarters establishes “Ice Information Center” in winter which prepares
drift ice information in the adjacent seas of Hokkaido and broadcast it promptly. This information is also
served by the following ways.
By the facsimile service+81-134-32-9301 (Service at Otaru, Polling method is required.)

By the Internet service

URL:
https://www1.kaiho.mlit.go.jp/KAN1/drift_ice/1center_eng.html

Vessels heading for areas where drift ice may be met shall always contact the above headquarters or
the nearest coast guard station for the information on drift ice and take advantage of it for theirnavigation. If drift ice that could be a navigational obstacle is discovered it must be reported to thecenter.
2. If a mass of drift ice exists in the distance, a peculiar brightness, white or yellow in color (reflection ofice), may often appear on the bottom side of low clouds and in other occasions clouds reflect blackish
spots or stripes (water sky).
Even in the case of no clouds, the sky above a mass of drift ice in the distance can often be noticed tobe whitish or yellowish by the careful sighting of the horizontal scene.

Stationary nets and aquaculture facilities. Along the coast in the area covered by this volume, lie
stationary nets anywhere within 2 M (6 M in places) from the shore. Further, aquaculture facilities for kelp,
brown seaweed, or scallop, etc. are established in most of shallow coastal areas and in small bays and they
narrow waterways in many places to which attention must be paid.
Usually simplified markers are attached to stationary nets and aquaculture facilities. However, in somecases they are difficult to sight as they are small in size and weak in illumination power, so caution isrequired. Locations and period which such facilities are placed, describe in the MDA Situational Indication
Linkages (MSIL).
Notification of facilities not described in the “MSIL”, which may hinder navigation is made throughgeneral Notices to Mariners and also Notices to Mariners issued by Regional Coast Guard Headquarters.
However, many fishery gears pursuant to common fishery rights such as gill net fishery, domesticatedfishery, artificial bank fishery, and the like are installed in the coastal waters which are more shallow thanabout 27 m (15 m in Okinawa) deep, but it is necessary to exercise caution because these are indicated neither
in “MSIL” nor in “Notices to Mariners.”“MSIL” URL https://www.msil.go.jp/【Delete table】

The weather conditions are severe with many depressions through the seasons, especially intense coldness
and NW winds in winter and dense fog in summer cause difficulties to navigation of vessels resulting in
numerous marine disasters. About half of them occur within 3 M offshore including areas near major ports
and harbours.
In addition, as the surrounding waters of Hokkaido rank among the world’s best fishing grounds andnumerous fishing vessels operate there all the year round, the ratio of the marine disasters suffered by fishingvessels is high in percentage of total.
Among those are the disasters caused by ice accumulation on hulls and structures or by drift ice under the
influence of weather and oceanographic conditions peculiar to the adjacent seas of Hokkaido.
Under the influence of depressions developing in their passage or the strong monsoon, marine disasters in
winter often bring about serious results with loss of life and vessels. Vessels intending to navigate in thewaters adjacent to Hokkaido, especially in the Japan Sea and Tsugaru Kaikyo have to pay full attention to theweather information, and if rough weather is expected it is necessary for vessels to operate with flexibility
such as delaying the departure from ports or, if vessels are underway, making early preparations for the roughweather, or seeking shelter at an early stage.
Areas in which marine disasters frequently occur. The types of marine disasters in areas with highfrequency are listed below.

Descriptions
The traffic is high in volume and ocean currents and tidal currents arestrong. There are counter currents along the coasts and tidal races
around Shiokubi Misaki. The visibility often worsens due to dense
fog in spring to summer, and snowstorms in winter.
Dense fog frequently appears in spring to summer and the visibility
is restricted. In addition fishing vessels are numerous due to theseareas constituting fishing grounds for salmon and trout. Especiallyareas near Kushiro Ko and Hanasaki Ko are those requiring attention.
Attention is also required to ice drifted into the Pacific and ice
accumulation on hulls in winter.
This area sees the most frequent occurrence of marine disasters
among the coasts of Hokkaido.
The visibility is restricted due to dense fog in spring to summer.
Attention must be paid to navigation especially in Notsuke Suido
where there are not many navigational marks and, in addition,
shallow areas lie scattered and the channel is narrow. Caution is also
required to drift ice in winter.

vessels entering into the port occasionally experience snowstorms and difficulties with navigation. Therefore, if
the chimneys in Kamiiso Factory of Taiheiyo Cement Corp. (41° 49′ N, 140° 38′ E) or their lights can not beseen, vessels should not attempt entering into the port for a while.
Anchorage. If vessels need to delay entering into the port for a while, the anchorage (depth: 18 m, bottom:
sand and mud) in the vicinity of the area 135° about 0.8 M from Hakodate Ko Outside Taiheiyo Cement

Directions. The passage leads from an area WNW of Daikoku Shima to an area W of Nippon Steel &Sumitomo Metal Wharf.
Six pairs of leading lights are installed on Nippon Steel & Sumitomo Metal Wharf and Nittsu Wharf, and apair of leading beacons is installed on Central Wharf. These are useful as berthing aids.
Entry restricted. In order to prevent fire hazard, no vessel is allowed to enter within a radius of 30 m fromtankers (including tank ships) carrying flammable dangerous substance at berthing or anchoring in the port
except the vessels permitted by Captain of the Port. It is required that such tankers show a sign “Loaded
flammable dangerous substance” which is discernible by night while berthing or anchoring in the port.
Precautions for entering the port. Fish preserves and aquaculture facilities are laid along the E side of N
Outer Breakwater and other aquaculture facilities in the W of Nima Misaki (42° 20.1′ N, 140° 55.8′ E), therefore
caution needs to be exercised.
At night, the various leading lights, light buoys, and the lights on N and S Breakwaters are often difficult todistinguish from the background city lights. The sight of harbour is often obstructed when vessels navigate thepassage because many vessels are usually at anchor within the port. In addition, it is necessary to exercise
caution because vessels entering to or leaving from Nippon Steel Wharf can meet vessels entering to or leavingfrom each southern wharf of the section 1 in the vicinity of the E end of the passage.
Overhead bridge. Hakucho O-Hashi (53 m high, with bridge lights) extends from an area S of the root of S
Breakwater to an area S of the root of N Breakwater, and is illuminated at night.
Anchorage. A quarantine anchorage is established WSW about 1.8 M of Poroshireto Misaki (42° 22.4′ N,
140° 54.9′ E) but it is necessary to exercise caution because there are aquaculture facilities nearby. The
anchorage for vessels carrying dangerous cargoes is designated on the N of the passage within Section 3 as acommon rule. The bottom of both inner and outer harbours are mostly sand and generally affords a goodholding.

General information. Nemuro Wan is an open bay entered between Nokkamappu Saki and Notsuke Saki
(43° 34′ N, 145° 21′ E). Notsuke Saki is made up of mostly dried-up muddy marshes. Onne To (lake) and Furen
Ko (lake) have their openings in the S part of the W coast. Nishibetsu Kawa disgorges into the sea at the N of
Furen Ko (lake). It is an important river for salmon fishery and numerous fishing nets are laid along the coast in
this bay during a fishing season from July to December. The NE part of the coast for 10 M between
Nokkamappu Saki and the mouth of Onne To is bordered by blackish rocks or shingle beaches and its hinterland
is low tablelands with about 60 m high. Rocky reefs with 5 m or less in depth lie scattered within 0.5 M off the
N shore of Nemuro Hanto.
The W part of the bay consists mainly of sandy beaches and a marshland lies inland between both the mouthsof Onne To (lake) and Nishietsu Kawa.
The SE part of the bay is about 15 to 25 m in depth and no dangerous reefs with 10 m or less in depth lie
further than 1 M off the N shore of Nemuro Hanto. The NW part of the bay is relatively shallow and contains
reefs such as Barasan Asase (43° 26.2′ N, 145° 18.2′ E) and Ryujin Tai (43° 32.6′ N, 145° 22.4′ E).

General information. Abashiri Wan is an open bay with the entrance about 50 M in length between
Shiretoko Misaki and Notoro Misaki (44° 06.8′ N, 144° 14.6′ E), and so is exposed to wind and waves from theN. The S side of the bay is shallow for a considerable distance from the shore, and a 20 m contour line runs
along 1 to 1.5 M offshore but there were no dangerous reefs off the bay.
The coast for 34 M in length between Shiretoko Misaki and Minehama Town (43° 56′ N, 144° 48′ E)
corresponds with the W coast of Shiretoko Hanto, and consists mainly of precipitous cliffy coasts although
sandy beaches and shingle beaches can be seen in places. The depth of water close to the shore is quite deep, butsome dangerous reefs lie along the coast. A shoal (44° 17.8′ N, 145° 15.0′ E) with 20 m in depth is located on
the WSW about 2 M of Poneorushi Misaki.
The coast for about 23 M in length between Minehama Town and Abashiri Ko is a sandy beach with a rangeof sand dunes. The coast contains the estuaries or inlets of Shari Kawa, Tofutsu Ko (lake), Mokoto Numa (pond)
and Abashiri Ko (lake). Aquaculture facilities are laid within 6 M offshore between Tofutsu Ko (lake) and the
NE of Abashiri Ko.
The coast for about 6 M in length between Abashiri Ko and Notoro Misaki consists mainly of continuous
precipitous cliffs.
This coast has Abashiri Ko for the 30,000 D/W class and Utoro Gyoko for the 500 t class as the ports
available for general vessels.

Port classification. Port designated by Port Regulations Law, Open port, Quarantine port, Immigration port,
Plant protection port, Important port.
General information. Abashiri Ko is situated at the estuary of Abashiri Kawa on the W shore of Abashiri
Wan. This port usually experiences calm weather between May and September, but a swell rolls into the port
during strong E winds. Ice forms in a part of the port from October to late December while NW winds blow hard.
These winds bring a swell which gets over the breakwater and makes vessels difficult to stay at the berth in the
port.
This port is the largest on the N coast of Hokkaido and serves as a fishery base in the Sea of Okhotsk at thesame time. There is a heavy traffic in the port with fishing boats during the season for salmon and trout fisheryfrom August to November.
The depth in the vicinity of the estuary tends to be shallower than that designated on charts by sedimentdeposition.
Safeguards against Typhoon and Tsunami. In order to prevent marine disasters caused by earthquake,tsunami, typhoon etc., The coast along the Sea of Okhotsk Earthquake, Tsunami, Typhoon etc. Safety Measures
Liaison Council is established to issue information on earthquake, tsunamis, typhoons etc. to vessels andrelevant parties in the port, and gives countermeasures to be taken including warning arrangements, evacuation

Port classification. Port designated by Port Regulations Law, Open port, Quarantine port, Immigration port,
Plant protection port, Important port.
General information. Monbetsu Ko is situated on the WNW about 41 M of Notoro Misaki. It is mainly
used by domestic vessels, cement carriers, foreign trade cargo vessels etc. It is also the fishery base in the Sea of
Okhotsk and numerous small fishing boats frequently enter into and depart from the port. While N to NE winds
blow hard, vessels can be greatly affected by wind waves and a swell in case of berthing and anchoring in theport except for No. 1 and 2 basins, because wind waves and a swell roll into the port from the outside.
There are reefs extending to the ENE about 0.6 M from Benten Misaki (44° 21.4′ N, 143° 21.8′ E). Onne Se(44° 21.6′ N, 143° 22.4′ E; 2.6 m in depth) lies on the E end of the reef, and the waves can break on it, so it iseasy to perceive during high waves but difficult to perceive during calm. Deep draught vessels should be careful
for changes in water depth as sand tends to silt up the port.
Safeguards against Typhoon and Tsunami. In order to prevent marine disasters caused by earthquake,tsunami, typhoon etc., The coast along the Sea of Okhotsk Earthquake, Tsunami, Typhoon etc. Safety Measures
Liaison Council is established to issue information on earthquake, tsunamis, typhoons etc. to vessels andrelevant parties in the port, and gives countermeasures to be taken including warning arrangements, evacuation

The coast is fringed with numerous rocky reefs and abundant seaweed. Dangerous reefs lie
scattered within 1 M offshore, whereas outside 1 M offshore, the depths are 10 m or more.
Esashi Ko (44° 56′ N, 142° 36′ E; Port designated by Port Regulations Law; Port Code: JP ESS) can
accommodate 500 t class vessels at the berths on this coast.
Weather. A stormy wind from the WSW known locally as “Hikata” blows around Omu Ko. A “Hikata”
occurs with an atmospheric distribution of southern high pressure and northern low pressure, upon which theatmospheric distribution suddenly causes a strong WSW wind to become even stronger when the isobars run
from the E and W, and thereby reaches 20 m/s occasionally. It occurs the most frequently from March to May,but it can occur with the passage of a typhoon or an atmospheric depression even in summer and autumn.
The stormy wind can reach around Saruru Misaki to the S, around Otoshibe Misaki to the N, and occasionallyaround Esachi Ko. The effect can be felt up to 12 M offshore.

510General information. This section describes the features regarding the coast for about 10 M in length
between Tokitomai Saki which is situated on the SE about 5 M of Soya Misaki and Tomiiso Gyoko (45° 27.8′ N,
141° 52.5′ E) which is located on the SW about 4 M of the same cape.
In the peninsula which contains Soya Misaki, a hill on the plateau stretches to the N and S, but becomes
gradually lower towards Soya Misaki in the N end.
The coast consists mainly of sandy beaches, but is fringed with rocky reefs widely extending within 1 M
offshore and is scattered with dangerous reefs. Soya Ko (45° 31.2′ N, 141° 56.9′ E, Port of refuge) is located at
the tip of the cape, but entry into the port can be difficult for large vessels on account of numerous rocky reefs
lying around the port entrance and its vicinity, so that it is used by small crafts of 20 t or less.
Fog. Fog appears with E winds from sunrise until noon in June, and from midnight until morning between
July and August. It occasionally lasts 3 days or so.

Ishikariwan Ko Kanrikumiai Leading lights (bearing 167.7° in aline) lead the way. The outside of the fairway is shallow because the fairway has been dredged.
Entry Restricted. In order to prevent fire hazard, no vessel is allowed to enter within a radius of 30 m fromtankers (including tank ships) carrying flammable dangerous substance at berthing or anchoring in the port
except the vessels permitted by Captain of the Port.
It is required that such tankers show a sign “Loaded flammable dangerous substance” which is discernible bynight while berthing or anchoring in the port.
Anchorage. Anchorages afford a poor holding because the bottom is mainly sand, and there is a risk of the
dragging anchor during high wind waves from the N, so that these are not suitable for anchoring.

General information. This is an open bay between Tate Iwa (43° 13.5′ N, 140° 55.2′ E) lying on the W
about 4.3 M of Takashima Misaki and Ryu-ga- Saki lying on the W about 2.5 M of Tare Iwa. The area in front of
Shioya Gyoko (43° 13.6′ N, 140° 55.1′ E) with a depth of 7 to 16 m in the E part of the bay is a good anchorage
for shelter during easterly winds. Kuri Sho (43° 13.3′ N, 140° 54.4′ E; an isolated reef with 3.6 m in depth) lieson the W about 900 m of Tate Iwa, and the outside of it descends steeply. The area around the S of the reef has arocky bottom and is not suitable for vessels as an anchorage.

Yoichi Wan (43° 12′ N, 140° 49′ E) (Chart JP28)
General information. This is an open bay entered between Kabuto Misaki (43° 12.9′ N, 140° 51.2′ E) andShiripa Misaki (43° 13.7′ N, 140° 47.2′ E). It opens to the N and the coast consists mainly of sandy beaches. The
entrance is about 3.4 M in width and the indentation is about 1.5 M in length. The depth gradually becomesshallow from 29 m at the middle of the entrance toward its head. The bottom is sand and contains noobstructions. However, during northeasterly winds, it affords no shelter as a swell rolls into there. Yoichi Ko(43° 13′ N, 140° 47′ E; Port designated by Port Regulations Law; Port Code: JP YIC) is situated on the W sideof the bay.
Oshoro Gyoko (43° 12.7′ N, 140° 51.5′ E) lying on the SW of Kabuto Misaki, consists of a small bay forabout 200 m in width which is indented to the SE for about 900 m. The depth gradually becomes shallow from
14.6 m at the entrance toward its head. The central area of the bay is 5 m or more in depth with a sandy bottom
and almost never influenced by wind or waves, so it affords shelter for small vessels.

Furubira Wan (43° 16′ N, 140° 40′ E) (Chart JP28)
25

30

35

General information. This is a small bay which is located on the SE side of Maruyama Misaki and opens
to the NE. It is sheltered from SW wind and waves, so that small vessels can seek shelter within Furubira Gyoko(43° 16′ N, 140° 38′ E) on the W shore in the bay where W winds are avoidable.
Violent winds occasionally gust from the Fukubira Kawa direction from mid April to late May.
There are numerous stationary nets and aquaculture facilities within the bay.

Shakotan Misaki ~ Kawashira Misaki (NW coast of Shakotan Hanto) (Chart JP28)
General information. The coast for about 5.5 M in length between Shakotan Misaki and Kamui Misaki
slightly curves inland in a bow shape. It is backed by Yobetsu Take and hilly terrain extending to Shakotan
Misaki, and thereby consists of cliffs with marine erosion and is fringed with sandy beaches.
The coast for about 7 M in length between Kamui Misaki and Kawashira Misaki (43° 13.2′ N, 140° 19.5′ E) isbacked by mountainous terrain faced with a stretch of high cliffs and is mostly fringed with sandy beaches.
Numerous rocks lie close to the shore but the depth outside 0.5 M offshore is 10 m or more.
Shallow reefs extend to the NW about 0.6 M from Kamui Misaki, and a sunken rock (43° 20.4′ N, 140° 20.4′

E) lies on the NW about 400 m of Menoko Iwa (10 m high).
Yobetsu Gyoko (43° 19.9′ N, 140° 22.8′ E; is divided into two areas that is called “Raikishi Chiku” on the Epart and Yobetsu Chiku on the W part) is located on the E around 2 M of Kamui Misaki.
Fog. Even if fog moves in this coast in May, it usually disperses soon. Fog in June generally comes fromthe western sea and can cover the entire sea and also lasts for as much as 10 hours or more at times, but usuallydisperses within a few hours. In July, the number of dense foggy days increases, but the fog usually disperses inseveral hours.
Precaution for navigation. Vessels may face a difficulty with navigating along the coast between Kamui
Misaki and Shirakami Misaki (41° 23.8′ N, 140° 11.8′ E) because of NW winds in winter. The coast between
these capes has few anchorages which is sheltered from W winds, except for an area off the E coast of Okushiri
To. Many vessels attempting to navigate along the coast have occurring causing marine disasters as a result of
capsizing or running aground.
When the wind changes direction after the passage of an atmospheric depression or a typhoon, it usually gains
in force after veering from the SW to NW, and thereby the sea becomes rough. Therefore, vessels should notneglect to take the necessary safety measures in case of both navigating and anchoring when strong westerly
winds are expected.

General information. This is an open bay entered between Biya-no-Saki and Benkei Misaki. It has anentarance for about 5 M in length and is indented toward the S for about 3.5 M. The W part is occupied by
Suttsu Ko (42° 48′ N, 140° 14′ E; Port designated by Port Regulations Law; Port Code: JP STU).
The depths become gradually shallower from the entrance toward the head of the bay. These are around 20 m
in depth within 1 M offshore and about 10 m in depth within 0.5 M offshore.
Numerous rocky reefs lie scattered close to the E and W coasts.
Shoals extend within about 500 m around Daimaru Saki, which include Daimaru Iso (42° 48.3′ N, 140° 13.5′
E; a dried-up rock) having a lighthouse on the reefs.
It is necessary to exercise caution in navigating inside the bay because numerous aquaculture facilities for
scallop are laid there.
Weather. A southerly wind blown into Uchiura Wan on the S coast of Hokkaido goes along the lowland
around Shubuto Kawa, and then gets stronger with passing through the narrow lowland extending to Suttu Town
when being spouted out into this bay. This wind known locally as “Dashi Kaze” blows between spring andsummer, and strengthens between May and July in particular and also sometimes lasts for a week or more. The
wind reaches an average maximum speed of 14 to 18 m/s so that has influence up to the N about 5 M of the bay,
but has no influence off the coast W of Benkei Misaki.
Fog. Radiating fog in the lower reaches of Shubuto Kawa frequently appears early in the morning on finedays, and hangs low over the sea but lifts quickly. Fog moving in from the Uchiura Wan region with S winds isdense around the mountains but sparser over the sea.

General information. Rocks and sunken reefs lie scattered throughout Suisho To. Sunken reefs with 10 m
or less in depth extend offshore in a direction between the NE and E of Tokkari Saki (43° 27.3′ N, 145° 57.0′ E)
at the NE extremity of the island.
Other sunken reefs with 4.5 m in depth lie on the NE about 1.2 M of the cape and 2.5 m in depth is on the E
about 1.6 M of the same cape. In addition, there are also sunken reefs (43° 30.0′ N, 146° 00.6′ E) with 2.8 m indepth lying almost in the middle between this cape and Aitomari Saki of Shibotsu To.
Rocky reefs extend within about 0.8 M off the S coast of Suisho To between Sankaku Saki (43° 25.5′ N, 145°
57.3′ E) and O Saki (43° 25.0′ N, 145° 54.0′ E). Tobi Sho (43° 24.9′ N, 145° 55.4′ E) lies on the WSW about 1.5
M of Sankaku Saki.
Benzaitomari Wan (43° 26.3′ N, 145° 53.4′ E) is an open bay on the W coast of Suisho To. Caution is required
because there are reefs extending within 0.5 M offshore almost in the middle at the head of the bay.
Bokisenbe Wan (43° 25.2′ N, 145° 54.0′ E) is located next to Benzaitomari Wan in the S, and suitable forsmall vessels as an anchorage for shelter in the area of Suisho To.
The mouse of this bay opens to the SW and the inside of the bay has a sandy bottom with 8 m or less in depth,so that the bay affords a good holding sheltered from the northeasterly winds.
There is a small cape with a steep cliff in the middle of the head of the bay. Both sides of it consist of shingle
beaches, whereas the N half of the head is a sandy beach.
Bara Shima (43° 25.3′ N, 145° 53.6′ E; 4.9 m high) is located on the NW side of the bay entrance.

Suisho Suido (43° 25′ N, 145° 59′ E) (Chart W8)
General information. This channel lies between Suisho To and Yuri To, which has the narrowest part for
about 3 M in width. A large shallow exists on the Suisho To side, and sunken reefs lying there in places.
In addition, there are other dangerous reefs such as a sunken reef with a depth of 2.5 m lying on the east about
1.6 M of Tokkari Saki and an isolated reef with a depth of 4.8 m lying further E for about 3.1 M, so that only
small vessels should attempt to navigate this channel.
Tidal currents. According to the observation results made in the area on the SE about 2 M from
Sankaku-Saki of Suisho-To, the tidal current flows to the W from about 3 hours after the ebb tide to about 3
hours after the flood tide, whereas flows to the E from about 3 hours after the flood tide to about 3 hours after
the ebb tide. These currents were observed with maximum rates of 0.8 kn to the W and 1.3 kn to the E
respectively.

Yuri To (43° 25′ N, 146° 04′ E) (Charts W8, W18)

25

30

General information. Foul ground lies within 0.5 M around Yuri To, so that vessels are recommended not
to enter within a 20 m contour line.
Tokoma Ko (43° 25.4′ N, 146° 03.5′ E) is a small bay located on the E side of Tomitomari Saki (43° 25.9′ N,
146° 02.8′ E) in Yuri To. The depth within the bay is 5 to 12 m and the bottom is sand and shingle, therefore it issuitable for small vessels as an anchorage for sheltering from S winds.
Toromoi Ko (43° 26′ N, 146° 05′ E) is a bay adjacent to the E of Tokoma Ko having larger anchorage thanthat in Tokoma Ko. It has about 900 m in width at the entrance, but the eastern side of the entrance is full ofreefs which reduce the navigable width to half.
The depth within the bay is 5 to 18 m, so that it is suitable for small vessels as an anchorage for shelteringfrom S winds. However, vessels should seek the anchorage with a sandy bottom in the W part of the bay becausemuch of the bottom is rock.

Harukaru Shima (43° 25′ N, 146° 10′ E) (Chart W18)
35

General information. There are three rocky islets to the NE of Harukaru Shima, and a sunken reef (43°26.0′ N, 146° 11.0′ E; less than 1 m in depth) extends to the NE for about 700 m from the outer one.
There are reefs extending to the SW for about 800 m from a small island (43° 24.6′ N, 146° 09.2′ E; 32 mhigh) which is located next to the SW side of Harukaru Shima, and an isolated rock (43° 24.4′ N, 146° 08.5′ E;
1.9 m in depth) lies on the outer end of the reefs.

35

General information. This bay is located on the SW side of the small peninsula which contains Atosa Take,and is entered between Poronotsu Hana (44° 48.8′ N, 147° 05.9′ E) and Kabara Misaki (44° 39.7′ N, 147° 00.7′
E) situated on the SSW about 10 M of it. Most of the bottom is fine sand. A shelter can be obtained during winds
from between N and S.
An isolated reef at the least depth of 11.4 m lies on the S about 5 M of Poronotsu Hana. This reef is difficult
to identify during calm seas, but is easily identifiable because it often gives rise to breakers during strong W
winds.
Weather. A mountain range with 500 to 700 m high lies on the hinterland of this bay, and the both sides of
it are low-lying lands which extend to the SE coast of Etorofu To, therefore this terrain can often gives rise tostrong S winds especially in summer off the entrance of the bay.
Fog. Sea fog often moves in from the SE coast of Etorofu To.
Tides. In this bay, Mean higher high water is 1.1 m, Mean lower low water is 0.3 m, and Mean sea level is
0.70 m.
