Directions.
1. When entering in the western part of the port, vessels pass through the fairway which is about 300 m inwidth with about 14 m in depth and located at the W of E Breakwater. This fairway is indicated by two lightbuoys inside the port, but the depth can suddenly become shallow in places with the exception of the
fairway, therefore it is necessary to exercise sufficient caution for keeping the course when wind waves
from between S and SSW are high around the breakwaters.
2. When entering in the eastern part of the port, vessels can use one leading mark and two leading lights: apair of leading mark indicates the center of the dredged fairway (14 to 17.5 m in depth; bearing 059° of two
marks in line); two pairs of leading lights indicate the fairway leading to Hokkaido-Sekiyu Kyodobichiku
Pier (bearing 082.7° of two lights in line) and the fairway leading to Central Wharf (bearing 012.3° of twolights in line), respectively.

Entry restricted. In order to prevent fire hazard, no vessel is allowed to enter within a radius of 30 m fromtankers (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.
Precautions for entering the port. Many domestic liners etc. as well as passenger liners and cargo ferries
enter into or depart from Tomakomai Ko, so that a traffic control system is applicable to certain vessels of 500 t
or more in Nishi Ko. The port tends to be congested with many inward and outward bound vessels in the earlymorning and evening, and even vessels being not under a traffic control are instructed to report when anchoring,entering into or departing from the port in advance to the signal station.
In narrow visibility times from early spring to summer when dense fog oftentimes foam, the restrictions may
be imposed at entry and departure under the agreement for the safety of sea navigation with Marine Traffic
Safety Conference of Tomakomai.
Obstructions. There are some submerged obstructions (42° 36.8′ N, 141° 36.1′ E; concrete blocks) at the
SW about 1 M of Tomakomai Ko W Breakwater Light. There are also numerous obstructions around the
Sea-berth.
Ex-dumping ground. There is a disused dumping ground at the S about 3.6 M of Tomakomai Ko W
Breakwater Light.
Overhead cable. An overhead cable with a vertical clearance of 55 m spans Yufutsu fairway from the shoreon the E side of Central N Wharf No. 4 Quay to the opposite shore.

Quarantine anchorage. Anchorages afford a poor holding because the bottom is mainly sand and pumice
etc., and there is a risk of the dragging anchor during high wind waves from the S, so that these are not suitable
for anchoring.
A quarantine anchorage is established near the harbour limit within Section 3 (42° 36.4′ N, 141° 36.0′ E).
Vessels carrying dangerous cargo shall anchor in Section 4.
Anchoring restricted. Vessels are restricted from anchoring within Section 1 and Section 2. Furthermore,
all vessels are prohibited from anchoring to ensure the security of inward-bound and outward-bound vessels inthe vicinity of the entrance of Nishi Ko.
Cautions for anchoring and evacuation advisory. The anchorage cannot be considered safe because theanchorage affords poor holding ground and the bottom is mostly sand and pumice. Some vessels have had
dragging anchors which resulted in stranding especially when a southerly strong wind is blowing.
For the reasons above, the Captain of the Port of Tomakomai issue “Advice for preventing dragging anchor”
which order the vessels anchoring inside and the vicinity of Tomakomai Ko to weigh anchor and evacuate incases that southerly winds with a velocity of 15m/s and more blow continuously.

sufficient distance from Shirito Sho and other dangerous reefs, and then proceed to an appropriate quay or
anchorage in Higashi Ku or Nishi Ku.
Entry Restricted. In order to prevent fire hazard, no vessel is allowed to enter within a radius of 30 m fromtankers (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 bynight while berthing or anchoring in the port.
Precautions for entering the port.
1. Vessels entering into or departing from the port are required to display the relevant International Codeflags to indicate their route.
2. Miscellaneous vessels should enter into or depart from the port through the passage between the W and N
Breakwater in Higashi Ku.
3. The passage may be congested due to the numerous fishing boats which gather from various places
during the fishing season.
4. When passing off Shirito Sho and Shirito Se in dense fog, vessels should endeavor to ascertain theirposition using all available means including radar watch and sounding.
Anchorage. A quarantine anchorage is established at the SW of the entrance to the passage (42° 58.4′ N,
144° 20.4′ E). Vessels carrying dangerous cargo shall anchor in the Outer Harbour.
The bottom of Section 2 and Section 3 in Higashi Ku is mostly mud, so that the anchorage in these sections
affords a good holding. Section 2 is better than Section 3 as an anchorage. The best one can be obtained in anarea at a depth of about 9 m with a muddy bottom, with Kushiro Ko Higashi Ku N Breakwater S Light bearing
230° at a distance of about 600 m.
The Outer Harbour is suitable for vessels as an emergency anchorage in low visibility with dense fog.
However, vessels require exercising caution for a wave meter, which lies on the bottom in the WSW about 1.5 M
of Shirito Hana, and submarine cables (power transmission lines) when lying at anchor.
Staying prohibited. In the area between the E end of the passage and Nusamai Bridge in Section 1 ofHigashi Ku, vessels are prohibited from staying such as stopping or lying at anchor.
Nishi Ku is also prohibited from lying at anchor.
Cautions for anchoring. There have been grounding accidents caused by dragging anchor when strong
westerly or southerly winds were blowing as the topography of the port is exposed to them. For this reason, theCaptain of the Port of Kushiro issues “Advice for preventing dragging anchor” when westerly or southerly winds
with a velocity of 15 m/s and more blow continuously, to warn vessels to exercise caution.
