From December to March, all services in the gorge (Kurobuchi and Sarutobi ferryboat, Kurobuchi restaurant, shuttle bus service and public bathrooms) are CLOSED due to the heavy snow fall. Though there are no snow inside the gorge, these are still closed.
During this period, there are no staffs for checking and cleaning the trail path for their safety reason.
On the middle of April, prefectural officers will inspect the trail condition and give the safety declaration. Then all service will be started.
If you try to enter the gorge before that, PLEASE BE AWARE OF ROCK FALL and SLIPPERY PATHS.
