There are 2 cylindrical tanks with spherical tops (50m high, 80m
diameter).

Passages. The E Passage and the W Passage are located respectively in the E side and W side of Shirogane W
Breakwater. In addition, the section No.2 in the port have two channels (Niida Kawa and Kyu-Mabechi Kawa) beyond
the Hachinohe O hashi, and there are controlled the port traffic by signals (Refer to item “Signals”).
Directions. Approaching from N, steer for Same Kado, bearing 180° from a position NE about 6 M of Shiriya Saki,
then enter the port passing W of Hachinohe Ko Outer Harbour Middle Breakwater N Light (40° 33.7' N, 141° 32.1' E).
Approaching from S, alter course to 270° when Samekado Light (40° 32.4' N, 141° 34.6' E) abeam with a distance of 3
M. Proceed to enter the port between the Middle Breakwater and No. 2 Middle Breakwater. But large vessels arerecommended to enter the port from the W of Middle breakwater due to the extension construction for No. 2 Middle
Breakwater.
Entry restricted. In order to prevent fire hazard, no vessel is allowed to enter within a radius of 30 m from tankers(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.
Precaution for entering the port. Ko Ne (40° 32.6' N, 141° 33.2' E; a rocky reef, minimum 3.2m deep) of the port
near a route and hardly no breakers. Near by shallows, and needs attention in anchor. Kabu Shima and No.2 Middle
Breakwater between are small, and cultured institution is installation, should avoid navigation other than a boat.
Hachinohe Ko approach is a place with many marine disasters of the fishing boat. In particular, the dense fog periodof the summer is fishing season of the cuttlefish and operates by night in an offing, many fishing boats returning to port
early in the morning. At this time, the large-size vessel arrival in port avoids morning and evening with many arrival anddeparture of the fishing boat, also, nearly navigation vessel in night avoids the operation area of fishing boat and should
navigation the outside.
Care is necessary against foul substances scattered in the port.
While large LNG tankers are entering or departing the port, entry is prohibited within the area connected following
points by a line: Middle Breakwater, Hattaro North Breakwater and the berth of ENEOS LNG Service Hachinohe LNG
Terminal.
Bridge buildings. There is Hachinohe Seagull Bridge (40° 32.0' N, 141° 31.5' E, height 4.5 ~ 5.5 m) between the S
extremity of Kawaragi No.1 Pier and the petroleum base SW of it, and Hachinohe O Hashi (Refer to item “Landmarks”)
at the entrance of Industrial Section 1 at the estuary of the Niida Kawa.
Anchorage. The S side of Shirogane N and W Breakwaters gives a good holding ground, but caution is requiredthat the roadstead is narrow and swells sometimes enter over the breakwaters in strong northerly winds. Section 3 isrecommended as an anchorage except in rough weather.
Quarantine anchorage (40° 33.9' N, 141° 33.1' E) is situated NE of Middle Breakwater. Anchorage for vessels carrying
dangerous substance is provided in Section 3.
