Boat and Weather

Here we provide monthly information about boat and weather for reference.
We sometimes cannot go to Koshima Island according to weather and conditions of the sea, as we go there by boat.
Note that we don't guarantee the below frequency of trips. Just for your information.
Please check weather forecasting by yourselves when you stay at the station, and change your reserch plan if necessary. Conditions of the sea become worse 2 or 3 days before arrivals of typhoons.
Local boat drivers take us to the island. The boat fee is 1000yen per person (over 3 persons).
