The following applies to the long weekend lasting from Saturday to the following Monday (2019/10/12-14).
Currently, Typhoon 19 is about to sweep across central Japan. Strong winds and heavy rain are expected from around midday Saturday (10/12) to late in the evening.
Beginning tomorrow around noon, the train service linking Matsumoto and Kamikochi will be suspended until further notice. They are expected to start operating the following morning, but at time of writing this can not be confirmed.
Regarding buses from Sawando to Kamikochi, no official announcement had been made at time of writing, but there is a high possibility that landslides or other effects of heavy rain could disrupt operations.
Hotels and lodges in central Kamikochi are expected to operate as normal this weekend.
Please exercise caution when traveling this weekend.
