Paragraph 2 TODO-GA-SAKI ~ KINKASAN

1520(Chart JP54)
General information. The Coast between Kabu Shima in Hachinohe Ko and Oshika Hanto has been dedicated as
Sanriku Fukko National Park (designated on March 31, 2015). The coastline between Todo-ga-Saki and Kinkasan isextremely rugged forming a Ria Coast. Many bays and inlets lie along the coast, but most of which, except Yamada
Wan and Ofunato Wan, are open to the E and subjected to swell.
Generally deep water lies close to the shore. However, islands and dangerous reefs are interspersed along the shore.
Especially both O Ne (s), each of which is located outside Yamada Wan and Otsuchi Wan, vessels should exercise caution
when navigating along the coast. In the vicinity of Ohako Saki (39° 21' N, 142° 00' E), tidal races may be experienced
when tidal currents and S winds meet.
Along this coasts, there are Kamaishi, Ofunato and some other ports which are classified as Port Designated by Port
Regulations Law. In addition, there are anchorages for large vessels such as Yamada Wan, Kesennuma Wan, Ogatsu Wan
and Onagawa Wan.

General information. Yamada Wan is entered between Ne Saki and Kone-ga-Saki, S about 2.2 M, both sides of theentrance of which consist of crumbled high cliffs. Two inlets lying between Ne Saki and Kasa-ga-Hana (a lighthouse at
the end), SW about 3.4 M are not suitable for anchorage because of the rocky bottom. The water inside Kasa-ga-Hanais surrounded by high mountains and very calm, most part of which is 20 ~ 50 m deep and gives a good holding ground;accordingly it affords good shelter for large and small vessels. But strict care is necessary to stationary nets andaquaculture facilities of seaweeds and shellfish, which are laid all over the bay.

Precaution for entering the port. The precautions below are necessary after the Great East Japan Earthquake
Earthquake.
1. Before entering port, detailed information related to port facilities, etc., must be acquired from the port authority
beforehand.
2. A part of the public wharfs are subsided, and so there is a case of overtopping waves at at high water.
3. In the case of anchoring within the port, vessels should pay attention to an assumption that an anchor becomesentangled to obstacles.
Caution: The inner harbour is narrow and traffic of fishing vessels is heavy particularly from September to next
January; so care is necessary in entering and leaving the port and in selecting anchorage.
Anchorage. Large vessels usually anchor near the quarantine anchorage (39° 15.4' N, 141° 54.7' E) E of Kama Saki.
The bottom N of the quarantine anchorage is mud or sand giving good holding ground but care should be taken in
selecting anchorage not to impede the passages of other vessels as this ground lies close to the fairway. Section 1 provides
good holding ground but it is narrow and scattered with foul bottoms. When anchoring in this port is considered unsafe
due to typhoon or for other reasons, Yamada Wan to the N or Ofunato Ko to the S can be recommended for refuge but itshould be noted that there are many stationary nets and aquaculture facilities in either area.
The anchorages for vessels carrying dangerous goods are located in Section 2.

(Chart JP80)
General information. Sagami Nada separates the coast between Turugi Saki and Iro Saki from O Shima; the N partis known as Sagami Wan.
The depth along the coast is generally deep to the shore. In the water outside 1.5 M offshore, depth is 20 m or moreand no dangerous reefs exist except in the vicinity of Hatsu Shima and Mikomoto Shima. However, in the coast of
Sagami Nada, it is dangerous to get close because many stationary nets are installed.
In recent years, large marine creatures such as the whales are witnessed well in this coastal waters.
There are no safe anchorages to large vessels. Doyo Nami hits this coast many times in summer.
Weather. In the vicinity of Tsurugi Saki, even in winter when NW monsoon is dominant, winds are relatively weak
and tend to be northerly or northeasterly affected by the landform. The climate is mild.
In summer, SW or westerly wind prevails; it is relatively cool due to developing land and sea breezes.
In Sagami Nada, generally N wind prevails in winter and in spring, S ~ SW wind is dominant in summer and N ~ NEwind is frequent in autumn. Winds are mostly strong in winter and weak in summer.
As Mikomoto Shima lies on the border between Sagami Nada and Enshu Nada, the weather in that vicinity tends tochange, which is influenced by the weather pattern of these two areas.
In some cases, strong SW winds suddenly turn to strong NE winds, and vice versa. Such winds, combined with strong
ocean currents and tidal currents, give rise to violent seas.
W wind in winter and E wind in summer is dominant in the vicinity of Iro Saki.
Fog. Fog usually sets in about midnight or in early morning in summer with weak winds. The peak season is June
and July, and then April comes next.
Tidal currents. Regarding Sagami Nada, the current is unstable. Around Mikomoto Shima, flood (ebb) stream flows
W (E); rates of E-going streams in springs sometimes attain more than 3 kn influenced by ocean current.

Tsurugi Saki ~ Jo-ga-Shima (Charts W92, JP1062)

General information. This coast between Tsurugi Saki and Jo-ga-Shima, which constitutes the S coast of Miura
Hanto, is a cliffy coast with many indentations. There are many rocky reefs along the coast but depths outside 0.5 M
offshore are 20 m or more. Misaki Ko lies N side of Jo-ga-Shima.
Precaution for navigation. In this coastal waters, stationary nets are installed so it is dangerous to get close.
Many recreational fishing boats appear about 1 M S of Jo-ga-Shima throughout the year.

THE SOUTH COAST OF HONSHU

291

There are not enough landmarks in this area but Ijika, Yoroi Saki, Anori Saki and Daio Saki Lights are good marks.
In the water along this coast, depths are irregular and there are many dangerous reefs such as Kuro Se (34° 20.2' N,
136° 54.8' E) and Abura Se (34° 19.4' N, 136° 54.8' E; depth 5 m). The depth outside 2 M offshore is 30 m or more.
There are stationary nets (throughout the year or from September to next June) and aquaculture facilities of seaweeds(from September to next May) in places along the shore between Yoroi Saki and Daio Saki.

(Chart JP93)
General information. This coast consists of steep bluffs; the coast line is irregular forming the ria coast with thickly
wooded mountains overhanging the shore.
The water along the coast is generally deep containing many coves in every size. Owase Wan (34° 04' N, 136° 17' E)
and Kata Wan (33° 57' N, 136° 15' E) afford shelter to large vessels. There are many other ports and bays affording
shelter to small vessels but care is necessary to aquaculture facilities of pearls and fish laid in every bay, which narrowanchorages.
Weather. The climate between Daio Saki and Shio-no-Misaki is extremely mild with the average atmospherictemperature in August which is the hottest month being 25 ~ 27°C, and in January which is the coldest month is about
7°C.
W or NW monsoons prevail in winter, W or N ~ NE winds are frequent in summer influenced by the land shape.
Owase, a major place on this coast, is a naturally made good port backed by mountains shielding it from winds.
The peak season of rainfall in Kii Hanto is from June to October. The maximum amount of precipitation appears in
September, about 720 mm at Owase and about 330 mm at Shio-no-Misaki.
Shelter. Owase Wan and Kata Wan are suitable for large vessels. Shelters for small vessels can be obtained in
Gokasho Ko (34° 19' N, 136° 41' E), Kamizaki Wan (34° 15' N, 136° 32' E), Kowaura Wan (34° 13' N, 136° 28' E),
Katsuura Wan (33° 36' N, 135° 57' E), Kushimoto Ko (33° 28' N, 135° 48' E) etc. in addition to the above two large bays.
But these anchorages are encumbered with aquaculture facilities of pearls and fish. Therefore anchorages may be filledwith vessels taking refuge in early time during rough weather.

Fuseda Suido and Approaches (Charts W78, W1090)
General information. This section describes mainly Fuseda Suido, and the coast of about 8.5 M between Daio Sakiand Goza Misaki.
The coast from Daio Saki to Fukaya Suido mostly consists of cliffs. The area westward from it, i.e. the S coast of
Sakishima Hanto (34° 16' N, 136° 48' E) is composed of mainly sandy beaches with some capes and points of cliffs. The
inland is a range of low hills except the W extremity of Sakishima Hanto.
Fukaya Suido (34° 15.9' N, 136° 51.6' E) is a straight cut through for intaking sea water from the open sea in order toprotect pearl culture in Ago Wan from damages of red tide. This straight affords channel for vessels up to 20 t class in
HW. Wagu Gyoko lies about 2 M W of Mugi Saki.
This coast is fringed with many dangerous reefs, especially off the central part, many dangerous reefs are widely
scattered, of which S extremity is situated about 3.5 M offshore. Fuseda Suido (34° 15' N, 136° 49' E) lies in a E-W
direction among these groups of dangerous reefs.
On the both of N and S sides of this channel, sunken reefs, drying rocks and rocky reefs are scattered, in which careful
ship handling is necessary when navigating.

Aikuchi Hana ~ Miki Saki (Chart W75)
General information. Mountains advance to the sea along the coast between Aikuchi Hana (34° 07' N, 136° 19' E)
and Miki Saki. The beaches facing the open sea consist of mostly cliffs.
Owase Wan is entered on the central part and Kuki Ura is on the southward neighbor.
The water along the coast is deep to the shore and the depth at 500 m offshore is 30 m or more except in the vicinityof Aikuchi Hana.
Owase Wan. (34° 03' N, 136° 17' E) This bay, enclosed by thickly wooded mountains, is large and entered between
Sawa Saki and Kuki Saki. It consists of four branch inlets; Owase Ko and Hikimoto Ko are suitable for anchorages tolarge vessels; Sugari Ura and Moto Sugari Ura merely afford shelters to small vessels and crafts except in S wind waves.
Caution is necessary to many stationary nets and aquaculture facilities of fish in the bay; fishing vessels may be
encountered at night between Aikuchi Hana and Miki Saki.
Kuki Ura. (34° 01' N, 136° 16' E) This is a long bay entered to the W. It is narrow, but there are no dangerous reefs
and the water is well sheltered form winds from every direction giving good anchorages to small vessels and crafts.
However, stationary nets are placed on the S side of the entrance for a whole year and there are many aquaculture
facilities inside from Kutsu Saki (34° 00.6' N, 136° 15.5' E), where vessels cannot enter. Kuki fishing port is located at
the head of Kuki Ura.
Overhead cables. Power transmission cables, a vertical clearance of 22 m, span from a position NW about 200 m
of Kutsu Saki to the southwestward opposite shore.
Anchorage. The outer bay E of Hai-no-Hana (34° 00.5' N, 136° 15.3' E) is comparatively safe except in strong E
wind when waves enter directly. It should be noted that fishing nets are laid on the circumference of the anchorage S of
Kutsu Saki, which restrict allowing sufficient anchor chain.

Port classification. Port designated by the Port Regulations Law, Open port, Quarantine port, Immigration port.
General information. Owase Wan is roughly divided into two areas, the NE part of which is Hikimoto Ko and theSW part is Owase Ko.
The port, sheltered by high mountains on its three sides, but open to the E, affords good anchorage to large vessels
except in strong E ~ SE winds, frequent particularly in August and September, in which waves enter the port. The water
depth within the harbour's inner breakwater is generally 4 ~ 8m. The water is generally calm, however many small
vessels and fishing ships enter and leave the area, and it is quite narrow.
As Owase Ko is within a prominent heavy rainfall area, tidal currents are reportedly complicate when the rivers
flowing into the port become swollen.

Port classification. Port designated by Port Regulations Law, Quarantine port.
General information. The port is situated N side of Katsuura Wan and is commonly called Kii-Katsuura Ko. Thisport, well protected by the land on its three sides and by Naka Shima lying in the S part of the bay, is one of the best
ports in the E coast of Kii Hanto.
Weather. NW and NE winds prevail through the year, but the influence is little. Swells occasionally enter the port
in strong E wind or when a typhoon approaches.
Marine disasters. In September 1959, when Ise Wan Typhoon hit this area, more than 50 vessels were at anchor,
but many of them suffered accidental damages due to vessel-to-vessel contact which resulted in many sunken vessels.

A bay on the NW side of Shionomisaki Hanto. (33°28' N, 135° 45' E) (Chart W99) This bay contains Fukuro Ko
which affords good temporary shelter for large vessels protected from winds between N and E. However, when winds
veer S or W, it will not permit safe anchoring due to the ingress of swell. Arita Gyoko is located at the head of Arida
Wan in the NW part. The N half of the bay is encumbered with many dangerous reefs.
Anchorage. The water, in the central part of the bay, N of a line indicated by the alignment of Fukuro Ko Leading
lights (33° 28.1' N, 135° 46.5' E; front light), the neighborhood 20 m deep, is recommended. But many fishing vessels
frequently gather and lay fishing nets in this area; so strict caution should be exercised especially in night time.
A bay on the SE side of Seto Saki. (33° 38' N, 135° 22' E) This is an open bay entered between Ise Saki and Seto
Saki. It affords anchorage in N ~ E winds but in westerly winds, breakers enter, which is not suitable for anchoring.
Small stationary nets are scattered along the shore in the bay.
