Weather and Climate In summer, the wind generally blows from the SE, while in winter the wind often blows
from the NW or the SW. The weather in the port is relatively mild throughout the year. However, as the port entrance isopen to the NW, strong northerly winds and large waves make cargo operations impossible (usually in winter,
reportedly 4-5 days a year) and also making it difficult for vessels to anchor in the port.
Oceanographic Phenomena In winter, when a NE to NW monsoon is blowing, cross sea occur in the area
between O Shima and Kashiwa Shima.
Entry restriction In order to prevent accidents due to ignition, general shipping are prohibited from entering a sea
area within 30m a tanker loading inflammable materials, including a tank ship, (within 50m of a tanker loaded withLPG) mooring in the harbour. Tankers carrying dangerous inflammable materials should display a banner visible atnight, reading “Dangerous Inflammable Cargo Aboard,” when moored in the harbour.
Anchorage West Harbour is 7-15m in depth, and the bottom is fine sand and hard mud containing coal dust, thus
ensuring good anchor holding. Oka Saki protects the port from somewhat northerly winds. East Harbour is 7-9m in
depth, and the bottom is fine sand, ensuring good anchor holding. This anchorage is more suitable than West Harbour
when a NW wind is blowing, but does not offer shelter during a typhoon.
The quarantine anchorage is located about 0.7M to the NW of the N end of O Shima.
The regular anchorage is West Harbour anchorage (Approx. Position 33° 28.8′ N 129° 56.8′ E): an area with a 100m
radius centred at a point 1,300m and 223° from the Karatsu Ko Nishi Ko East Breakwater West Light (33° 29.3′ N
129° 57.4′ E).

Outline The centre of the channel is about 7M wide and about 50m in depth. In the N side of the E entrance is Na
Shima and other a lot of rocks and reefs. There is an island called Eboshi Shima in the centre of the E entrance. And
also there is an island called Futagami Shima in the centre of the W entrance. As such, the narrowest point is 3.5M
wide.
Landmarks When visibility is good, Eboshi Shima (33° 41′ N 129° 59′ E, 42m in height) at the E entrance of thechannel and Futagami Shima (33° 36′ N 129° 33′ E, 91m in height) at the W entrance of the channel are good
landmarks. And also Mt. Take-no-Tsuji (33° 44.5′ N 129° 42.6′ E, 213m in height) on the Iki Shima and islands thosethat in the S of the channel are good landmarks.
Clearing line The line from which Futagamishima Light (33 36.3′ N 129 33.2′ E) is seen at 250 passes very
close to the S of Gabu Se (sunken rock, 33 43.1′ N 129 54.8′ E), Baku Se (33 42.5′ N 129 52.4′ E, 3.2m in depth)

Futa Shima

Imari Wan

Ao Shima(Photographed in Sep. 2019)

Outline A big bay extends over two prefectures, Saga and Nagasaki, and is indented by a number of small
and big islands extending from the entrance to the bay to the inner bay. The bay is divided between an outer andinner bay. Imari Ko is at the head of the inner bay.
To enter Imari Wan, there are three channels: Aoshima Suido, Tsusaki Suido and Hibi Suido. Hibi Suido has
dangerous reefs so large vessels cannot proceed through it. Aoshima Suido and Tsusaki Suido can be entered and left
even at night as main channels.
Aoshima Suido (33° 25′ N 129° 42′ E) is about 500m wide with a depth of 20m. There are shallow reefs extending
from the E end of Izu Shima to the channel and dangerous reefs such as rock mounds extending from the NE part of Ao
Shima, but the W side of Ogo-no-Shima is relatively deep and safe. There are aquaculture facilities on the S side of
Ogo-no-Shima (57m in height).
Tsusaki Suido (33° 24′ N 129° 40′ E) is a channel with about 400m wide with a depth of 20m. There are aquaculture
facilities in the N side of the narrowest part of Tsusaki Suido and the S side of Ao Shima, therefore extra attention
should be paid for these aquaculture facilities.
The water is 10-25m in depth in the Imabuku Ko, and bottom is mostly mud and good for anchoring. Therefore,
vessels of around 2,000t use there for shelter during typhoons.
There are plants of Kyushu L.P.G. Fukushima Terminal Co., Ltd. in the vicinity of the NW of Shiraiwa Hana,
located inside Imari Ko, on the S end of Fuku Shima. Large LPG tankers normally pass through Aoshima Suido,
enter and leave these plant through the area from W to S of a group of sunken rocks with a depth of 20m or less
(Tugboats stand by in the area) at a reef bank off the S extremity of Taka Shima (33 24.3′ N 129 44.0′ E).

Paragraph 2

TSUSHIMA (Chart W173)

Outline Tsushima is a part of Nagasaki prefecture. It is made up of 2 islands, Kami Shima and Shimo Shima and isapproximately 73km in length from N to S and 18km in width at its widest position. The island’s coast is extremely
tortuous with many indentations, which provide small harbours and inlets, in which small vessels can shelter fromrough weather. Izuhara Ko, on the central part of the E coast of Shimo Shima, and Hitakatsu Ko, on the northern part of
the E coast of Kami Shima, are representative harbour. Car ferry and high-speed craft are operated for service between
Izuhara Ko and Ashibe Ko, Gonoura Ko, both on Iki Shima, to Hakata Ko, and car ferry is operated for service between
Hitakatsu Ko to Hakata Ko, and as well as high-speed craft service to Busan {Korea}. Also, Tsushima airport locatedon the northern part of the Kami Shima E coast provides regular flights for Nagasaki and Fukuoka.
The sea area in the vicinity of both the S and N ends of the island is dotted with reefs to a distance of about 1.5M
from the shore. The entire coast has many aquaculture facilities, gill nets, stationary nets, etc. Also, bait fishing iscarried out along the coast from the N, through the W to the S, so vessels entering any of the ports or navigating along
the coast in this area must exercise caution.
Shelters There are many shelters on the coast of Tsushima. Generally, shelters on the E coast are exposed to winds
from E, and shelters on the W coast are exposed to winds from W. The shelters on the Tsushima coast are shown in the
below.

area within 30m a tanker loading inflammable materials mooring in the harbour.
Weather and Climate Mostly N winds all year around and the NW winds follow
Caution When a typhoon pass the E side of this harbour, vessels cannot anchor there due to high waves and strong
winds in the harbour, so they should find refuge in either Aso Wan located between Kami Shima and Shimo Shima orin Miura Wan. When SE wind velocity reaches 20m/s, entering and leaving the port is extremely dangerous. Take carein not to lose any opportunity.
Typhoon and tsunami safety measures In order to prevent accidents due to typhoons and tsunamis and otherabnormal weather, Abnormal Weather Countermeasure Committee of Izuhara Ko and others is established and they
manages typhoon and tsunami damage prevention countermeasures, such as the communication of typhoon andtsunami information, warnings, and the imposition and lifting of evacuation advisories for all vessels in the harbour.

8918.5-45m in depth, but a shoal with about 13m of depth exists in some areas.
Precautions on entering the passage
1. The passage leading to Nagasaki Ko is safe to navigate, but it may be difficult to find the entrance to the port froma distance for the first time.
2. Caution is required as it is narrow inside the harbour and many vessels are coming in and going out.
3. In the coastal area of Section 2 and Section 3, there is a number of oil tanks which require great caution about firewithin the port.
Pilotage Pilotage can be arranged through the Nagasaki Pilot Association. (See “Chapter 6 Pilotage” in Part 1)
Secondary undulation (Seiche) Large oscillations of water level in Nagasaki bay are called Abiki in local dialect.
At the head of the port, a rise of 1m is frequently experienced. The largest Abiki ever observed occurred on 31st March,
1979 and recorded an amplitude of 278 cm over a period of 35 minutes. Generally, Abiki occurs during winter andspring, rarely occurs in mid-summer. It is considered that seiches are caused by a metrological phenomenon which
resulted in disturbances in sea level though, it has not yet led to a successful prediction of seiches.

Shima from the S is about 5M long, about 300m wide, have been dredged to a depth of 12m and is marked by 5 lightbuoys. There is a shallow area with a depth of less than 10m on N of O-Tsuku Shima, therefore, vessels must not
navigate off the fairway.
The new port is divided into the inner port and the outer port. The fairway to the inner port branches off from thepreviously-mentioned fairway, with a depth of 5 to 8m, and is indicated by 3 light buoys.
The entrance of the fairway to the oil basin lies about 600m N of O Shima. The fairway lies between N Groin(submerged by high tides, there is a lighthouse on NW end of N Groin) and S Groin (submerged by high tides). The
fairway is about 40m wide and dredged to about 5m. The anchorage area is shallow with a depth 5 to 6m.
