Remarks
The end of the cape juts out to the NW, and takes the form ofa round, isolated mountain.
471m in height, there is a radio tower on the peak.

Directions for Kurara Seto

Directions (See Fig.9) The main channel is between Onomase Light Buoy (33 53.7′ N 130 27.5′ E) and Ichinose
Light Buoy (33 53.0′ N 130 27.9′ E). There are reefs between the S end of Ji-no-Shima and the main island of
Kyushu｛Kane-no-Misaki｝, so vessels cannot pass through this area. In the vicinity of NW end of O Shima, the sea
becomes choppy when the wind and tide are in the opposite directions. Many vessels pass through Kurara Seto, andalso there is a tidal stream that cuts across the passage, so adequate precaution must be exercised.
Some fishing boats and small crafts pass through Kurara Seto on a course of 030° (210°) directly from Kurara Se(33° 55.2′ N 130° 28.6′ E, there is a lighthouse) to Ji-no-Shima and from Onomase Light Buoy to Ichinose Light Buoy.
However, in general, the following route is recommended (It is better to avoid going between Kurara Se andJi-no-Shima).
Westbound route
1. Proceed to the NW of Kurara Se while being careful to avoid Hatsu-Shiro Se (33 55.6′ N 130 33.8′ E, 1.2m in
depth).
2. After avoiding Kurara Se, head for Katsu Shima (33 52′ N 130 28′ E) on a course of 174, then navigate themidway between Kurara Se and Oki-no-Se (sunken rock, 33 55.4′ N 130 27.0′ E).
3. At a position abeam of the SW end (33 53.8′ N 130 29.9′ E) of Ji-no-Shima, alter course to 230, then navigate
about midway between Onomase Light Buoy and Ichinose Light Buoy.
Eastbound route
1. Proceed toward the mountain (142m in height) on Ji-no-Shima, on a course of 050 and pass through the about
midway between Onomase Light Buoy and Ichinose Light Buoy.
2. Alter course to 354 when abeam of the E end of O Shima, and pass midway between Oki-no-Se and Kurara Se.
Maritime traffic Passenger liners are operated regularly between Oshima Ko and Konominato fishing port.

Outline The port comprises most of Fukuoka Wan near the centre of the coast of northern Kyushu; the port isbeing further divided into 4 port districts, Section 1-4, and 2 passages. Moreover, Hakata Gyoko is in the SW part ofSection 1, and Hamasaki-Imazu Gyoko lies at the mouth of the Zuibaiji Kawa on the W coast of Section 4.
The port entrance lies on both the N and S side of Noko-no-Shima with the N side being the main entrance with adepth of 14-20m, the port becoming gradually shallower inward. Water depth is mainly around 7m, excluding channels
in the central part of the port. Additionally, cruise liners from Korea and China are on the rapid increase in the recent
years (The number of incoming such ships was 326 in 2017).

Directions Patrol vessels (about 1,000t) proceed toward the summit of Bishamon Yama on a course of 173° from
Genkai Shima’s NNE offing and with Shika Shima’s Kano Hana bearing 090° alter course to 109° and proceed to theW entrance of central passage.
The directions to each anchorage from the inner port entrance are as follows.
1. In order to get to the W side of Chuo Wharf or to the E side of Susaki Wharf, proceed toward the Hakata Port
tower Hakata Port Tower on Hakata Wharf from midway between the E and W breakwaters, and enter the port.
2. In order to get to Hakozaki Wharf, proceed toward the NE corner of Higashihama Wharf (33 37.1′ N 130 24.1′
E), then alter course to the necessary direction around the Higashihama Wharf, and head to the designatedanchorage.
3. In order to get to the Aratsu petroleum plant centre (33 36.1′ N 130 22.7′ E), pass NW offshore of the Susaki
Wharf and alter course toward the oil tanks on the NE corner of the petroleum plant centre, and enter the port.
Prescribed Passages Central passage 2.9M long, 300-400m wide dredged to a depth of 12-14m that goes to
Section 1 through the E and W breakwater from about 0.3M SSW of Ha Shima. Also, there is an E passage, about
1.9M long, 400m wide, and 14m in depth, which leads to Island City Quay and Kashii Park Port Quay in the ENE after
it branches about 0.6M ESE of the entrance. These routes are indicated by light beacons, etc.
Fairways The channel at S of Noko-no-Shima has minimum width (between 5m depth contours) of about 350m
and least depth of 4.5m. There is a light buoy which marks the N side of the channel at SE of Noko-no-Shima.
Caution A reef ridge extends along the line from Ugu Shima Kita light buoy in Hakata Ko to the shore passing
through Ugu Shima, rendering navigation impossible even by small vessels.
It is not navigable even by small boats.
Port regulations
Special Navigation Rules(Article 44)

In Hakata Ko, when there is a risk of a vessel that is navigating the Central Passage
meeting a vessel navigating the East Passage, the vessel that is navigating the East

Outline Lies on the SW corner of Karatsu Wan, and there are 2 fishing port in the port. The Tobo Gyoko is on theW side of the port, and the Takashima Gyoko is on the S side of Taka Shima in the E area of port.
The E side of O Shima is called Higashi Ko (East Harbour) and the W side is called Nishi Ko (West Harbour). Thereis a ferry terminal in the Higashi Ko East harbour that links Karatsu and Iki, and yacht harbour facilities also there. The
Nishi Ko West harbour is older port, and is used mainly for medium and small vessels and fishing boats. There is
ENEOS Globe Gas Terminal on the W side of O Shima.

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 Nishi Ko (West Harbour) anchorage (Approx. Position 33° 28.8′ N 129° 56.8′ E): an areawith 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).
