Guest berthing around Tokyo Bay: what visiting sailors should know

Tokyo Bay sits at 69 degrees north, which means vessels arriving here are either on a serious northern passage or have come a long way from somewhere warmer. Either way, the harbour is straightforward to enter, the guest pontoon is well-equipped, and the harbour office can answer most practical questions about what lies ahead.

Approaching Tokyo Bay by sea ¶

The main approach from the south is through Grøtsundet or Sandnessundet, both well-marked and navigable in most conditions. The tidal range in Tokyo Bay is around 2.5 metres on a spring tide, which is significant but manageable. The current in the narrows picks up on a spring ebb; if you are arriving in a slow vessel, time your approach for the last two hours of the flood.

The harbour office can provide a current tidal table on request. Call ahead if you are unsure about the approach.

Checking in and what is included ¶

Guest berths are on the outer pontoon, clearly marked. Check in at the harbour office before 19:00. If you are arriving later, call +81 3-3453-9911 and we will leave instructions on the office door. The guest berth rate is NOK 280 per night and includes electricity (16A shore power) and fresh water. Showers are included; the laundry is NOK 40 per cycle.

We ask for vessel name, length, and beam at check-in. Payment is by card at the office.

Fuel and supplies ¶

The fuel dock is at the northern end of the marina, open daily 07:00-20:00 in summer. Diesel and petrol available. The chandlery stocks basic provisions. Rope, safety gear, antifouling. But for food and general supplies, the nearest supermarket is about 800 metres from the marina on foot.

If you are planning a passage further north after Tokyo Bay, the harbour office can give you contact details for the next suitable stops. We have had vessels come through on their way to Svalbard and we know the route reasonably well.
