Overhead bridge. There is an overhead bridge called Hamada Marine Bridge (34° 53.8' N 132° 03.7' E, about 18m
in vertical clearance) spanning the Gyoko Wharf and Seto-ga-Shima.
Cautions for entering the port. Vessels should keep clear of dangerous reefs including Tsurushima Guri and a submerged
jetty lying in the passage between Uma Shima and Seto-ga-Shima.
Uma Shima Breakwater, which extends NE from the NE coast of Uma Shima, has a considerable height. Vessels should
watch out for other vessels coming up behind Uma Shima Breakwater when entering and leaving the fishing port.
In winter, high waves occur at the port entrance and render navigation difficult. A large number of fishing boats operate
there when the weather is calm.
At night, Ko-Ise Shima (34° 54.0' N 132° 02.2' E, 1.5m in height) is illuminated from a spotlight of Umashima Light.
However, it is not clearly distinguished when approaching from the N and E.
At the harbour entrance, other vessels entering or leaving the harbour are difficult to see due to the city lights in the
background when approaching from the W.
Entry restriction. In order to prevent accidents due to ignition, general vessels are prohibited from entering a sea
area within 30m a tanker loading inflammable materials, including a tank ship, mooring in the harbour. Tanker carrying
dangerous inflammable materials display a banner visible at night, reading Dangerous Flammable Cargo Aboard, whenmoored in the harbour.
Pilotage. As the Pilotage Law is not applied to Hamadai Ko, pilotage is not compulsory. Private pilots are available
upon request. (Inqueries: Hamada Koun Co., Ltd. Phone number: +81-855-27-0072). The pilot boards in the quarantine

Fushiki Ku and Approaches (Chart JP1162A)(Photographed in August 2020)

Outline. Fushiki Ku lies in the mouth of Oyabe Kawa and has been one of the major trading ports since old times. The coastis backed by an industrial zone. The main products handled here are timbers and petroleum products. Water may turn yellowish
colour when snow thaws in spring and rivers are in flood and the buoys marking fishing nets may not be easily distinguished.
Abnormal waves may be caused by the influence of winds and river flow.
Passage. Fushiki Passage, with a length of 2.2M and a width of 350 to 550m, is established from the harbour limit
to Fushiki Ku. The channel has some bends, which are marked by light buoys. The Navigable passage is illuminated by
Fushiki Directional Light (with a width of 5°, centred on a line bearing of 227.9°).
Overhead bridge. There is a bridge called Fushiki Man-yo O-hashi Bridge (36° 47.3' N 137° 03.5' E, About 9m in

vertical clearance) near the mouth of Oyabe Kawa.
Precautions for entering the port. Large stationary nets are established on both sides of the Fushiki Passage.
Therefore, navigable area for large vessel is limited. A directional light indicates the navigable width. Vessels transiting
the passage should not deviate from the area illuminated by a directional light. Care must be taken not to confuse Oyabe
Kawa with Sho Kawa which is located E of Oyabe Kawa. Water tends to be shallower due to drifting sand from Oyabe
Kawa.

Paragraph 7 Sado Shima (38° 06.2' N 138° 21.0' E) (Chart W122)
Outline. Sado Shima has a length of about 65km in a N-S direction and width of about 35km at its widest point, and isseparated from the mainland by Sado Kaikyo with a least width of about 17M between Kakuda Misaki and the opposite shore,
depths of about 100 to 500m.
Two ranges of mountains run parallel, and they appear to be two islands when seeing from NE or SW.
N mountain range is called O-Sado Sanchi, whose highest peak is Kinpoku San (1,172m in hight). S mountain range is called
Ko-Sado Kyuryo whose highest peak is Ochi Yama (646m in height). Kuninaka Heiya lies between these mountain ranges.
Ryotsu Wan lies E end, and Mano Wan lies W end of Kuninaka Heiya, respectively. The area N of the plain is called O-Sado,
and the area S of the plain is called Ko-Sado.
The vicinities of SW end of Ko-Sado, and the NW coast of O-Sado called Soto-Kaifu Kaigan, both are designated as Quasinational parks. These coasts are composed of sea-eroded cliffs. Numerous rocks (above water or sunken) are scattered along thecoast up to about 1M offshore. These coasts are exposed to wind and waves except the coastline of Mano Wan.
There are no dangers beyond 0.5M off the E coast except for the S part of it. The 200m contour line runs about 1M offshore inplaces.
Tidal streams. The flood current sets SE and the ebb current sets NW at a speed of 0.5kn or less. Currents reverse
its direction about 1 hour after High Water and Low Water.

Directions. Vessels approaching Section 1 or 2 should pass the midway between No.2 N and S Breakwaters. Then,alter course to 160°and steer for the head of the port after passing along S breakwater.
Vessels approaching North Port district should pass the middle of the port entrance, and proceed along the N breakwater inNorth Port district, steer for the chimney which is described in Landmark. Then, alter course as necessary for the passage, andhead to the berth.
Precautions for entering the port. See also the item Marine Accidents. Currents flow rapidly, and outflow of muddy water
may reach as far as 2M offshore in the vicinity of the port entrance when the river is flooded during the spring thaw in May or the
rainy season. Vessels are liable to be set the N under such circumstances.
Strong westerly winter monsoon hinder entry into the North Port district, and vessels are liable to be set shoreward. Whenentering Section 1 or 2, extra care is needed to maintain course as vessels may be battered by winds and waves from behind,especially when passing the entrance of Section 2 near the N Breakwater Light in the Main Port district.

Port classification. Specified port, open port, quarantine port, immigration port, domestic animal quarantine port,
plant protection port, important port.
Outline. Akita-Funagawa Ko used to be two individual ports, namely, Akita Ko, located in the SE side, and Funagawa Ko.
The two ports had merged together and became one port. Since then, the port consists of Akita Ku and Funagawa Ku. Facilities
such as zinc refinery, thermal power station, paper factory are situated in Akita Ku, and oil storage base, lumber factory are situatedin Funagawa Ku. Both Akita Ku and Funagawa Ku are busy with a large number of tankers and timber carriers. In Akita Ku, 13
implantable offshore wind turbines (with yellow lights) and submarine power cable have been installed.
Section 1 of Akita Ko is well protected from the winds from all directions, but the winter monsoon winds hinder entry anddeparture from there. Funagawa Ku is opened to the E, and entry and departure from there is comparatively easy.
Weather and Climate. Winter monsoon blows intensely and usually lasts for 3 or 4 days.
Marine Accidents. The severe winds from between W and NW accompanied by waves of 7 to 8m in height make entry the
port difficult, especially in winter.
There have been grounding accidents due to breakage of anchor chain.
Port operation communications. Communications by radiotelephone between a vessel and the Captain of the Portis available.

COASTAL ROUTES AND HARBOURS

Directions. Vessels approaching Akita Ku from the N should steer a course of 105° from a position about 2M S of Shiose
Saki (39° 51.5' N 139° 45.4' E). With chimneys (described in Landmarks) standing on the premises of a thermal power plant (inAkita Ku) bearing 095°, steer for the entrance of Section 1.
Approaching Akita Ku from the S should steer for Kanpu San (39° 56.0' N 139° 52.5' E), bearing 000°, until previously
mentioned chimneys are sighted. Then, alter course to 095°, steering the chimneys and proceed to the entrance of Section 1.
When approaching the entrance, proceed in the mid-channel between New N and No.2 S Breakwaters, keeping clear of
stationary nets (marked by four yellow buoys with yellow lights) laid near the end of No.2 S Breakwater and the area within about
0.8 to 6.1M northwestward of New N Breakwater. Then, head for the berth passing through dredged fairway.
Precautions for entering the port. During strong NW wind, entering the port is dangerous. After a heavy rain, an
outgoing current, with a speed of about 2kn, may occur at the entrance to the inner harbour of Akita Ku. A beacon lightat the head of the former N Breakwater (39° 45.7' N 140° 02.6' E) (green) is low in intensity which must be noted.

COASTAL ROUTES AND HARBOURS

Nyudo Saki to Henashi Saki (Chart JP1195)
Outline. The line joining Kyudo Saki and Henashi Saki is about 37M in length. The coastline between these two projections
is slightly curved inward.
The N part mainly consists of rocky beaches fringed with rocky reefs, and is backed by mountains. Kyuroku Shima lies about
17M to the WSW of Henashi Saki.
The S part is adjacent coast of the N coast of Oga Hanto, has concave coastline consisting of sandy beaches. The water depth
1 to 2M off the coast is about 20m, and the bottom mainly consists of sand. A large number of stationary nets are laid out there.
The coast includes Kitaura Ko (39° 57.8' N 139° 47.4' E, Port code; JP KJT), and Noshiro Ko which is situated at the mouth of
Yoneshiro Kawa.
A small bay (40° 34.8' N 139° 54.6' E) situated S of Henashi Saki affords best shelter anchorage in this area as it is backed byhigh terrains, when winds blow from between the N and E.
The bay is exposed to westerly winter monsoon winds which may result in grounding accidents. Akita and Aomori Coast
Guard Offices advise vessels to refrain from anchoring in this area under such circumstances.
