How To Enter Kushiro Port and Things To Be Aware of When Entering
1.How to enter Kushiro Port
（１）How to enter the East Area
When entering the port from Nemuro, navigate while maintaining a safe distance from the Shiritosho Light
Beacon (42°57'40.0"N, 144°22'06.8"E) to the south of the East Area, veer to the west of the quarantine
anchorage at an appropriate location, and when approaching the quarantine anchorage, gradually turn right
toward the outer edge of the anchorage before going into the port entrance.
When entering the port from Cape Erimo, the two chimneys of the Nippon Paper plant one kilometer
north from the mouth of the Shinkushiro River serve as a landmark. When approaching the port, gradually
turn right toward the outer edge of the quarantine anchorage, and go into the port entrance.
（２）How to enter the East Area
Navigate to the west of the detached breakwater (1,750 m in length, with lighthouses at the eastern edge and
the western edge) to the southwest of the south lighthouse in the West Area while maintaining a safe distance
from it, then turn right and go into the port entrance.
It is not recommended to enter the port between the western edge of the south breakwater in the West Area
and the eastern edge of the detached breakwater since it requires a large-angle turn.
（３）Course indication
1) Any vessel sailing in the harbor of Kushiro Port or near the port boundary must let other vessels know its
course by sending a signal regarding its destination through an automatic identification system as prescribed
by the Commandant of the Japan Coast Guard.
However, this does not apply to vessels without any automatic identification system or with a system that
is not in use pursuant to the provisos in Article 3-16 of the Ordinance for Enforcement of the Mariners Act.

Q（6）
Q（6）
2. Points to note when entering the port
(1) Shirito Reef (with the Shiritosho Light Beacon to the south), made up of rocks awash, rocks that become
covered and uncovered, etc. lies in the waters 0.5 miles offshore near the southeastern coast of Kushiro Port.
Please be alert when sailing nearby, as grounding accidents have often occurred there.
(2) From April to October every year, as many fishing boats gather from across the country and are based at
Kushiro Port, the marine traffic gets heavy in the harbor and its surrounding areas. Please be alert.
(3) Dense fog is often present over the waters around Kushiro Port. In summer, such conditions can continue for
several days. When visibility is poor due to dense fog, it is essential to strengthen surveillance using radar
and navigate at safe speeds.
(4) Timber is sometimes unloaded in water and carried on a raft in the waters around the central pier in the East
Area. Please be alert when sailing nearby.
(5) A variety of construction work is underway in the West Area and its surrounding waters. Be careful of
working boats traveling back and forth there.
(6) Fixed nets are set in waters around Shirito Reef and along the coast to the west of the West Area. Please
sail carefully.
3. Anchoring at Kushiro Port
(1) Ordinary vessels can anchor in the Outer Port as well as in Section 2 and Section 3 of the East Area.
(2) Vessels loaded with dangerous goods (including non-gas-free vessels) can anchor in the Outer Port (advance
designation of the anchoring position from the Captain of Kushiro Port is needed), but not in the East Area or
the West Area.
(3) In line with Announcement No. 8 by the Captain of the Port (November 16, 2001), no vessels are permitted to
anchor in the West Area of Kushiro Port for the time being in order to secure the waterway.

Captain of the Port on January 10, 1995 shall be lifted on November 16, 2001 in line with the completion

4. Points to note when anchoring at the port
Continuous strong southerly winds may cause anchors to drag in Kushiro Port and its surrounding waters. Vessels
at anchor or vessels intending to anchor are requested to note the following points:
(1) Get a clear grasp of the area and bottom sediment at the point of anchorage and the distance from the shore
to the point of anchorage to decide the numbers of anchors and shackles.
(2) Stay abreast of the weather conditions to take appropriate actions with any changes (shifting anchor, moving
to a safer port or sea area, etc.).
(3) Make an appropriate surveillance and keep listening to VHF.
(4) Any vessels equipped with AIS (automatic identification system) should leave the system on and set it to sound
a ring alert.
*The Captain of Kushiro Port issues an anchor dragging advisory if strong southerly winds of 15 m/s or more are
judged to continuously blow at Kushiro Port.
