No injuries were reported in the landslide, which cut off access to Nakabusa Onsen in Azumino, a historic hot spring resort in Nagano Prefecture, with more than 200 years of history, Kyodo News Agency reported.

Located about 1,462 meters above sea level, the resort is known for its natural hot spring waters and serves as a popular starting point for hiking routes in the Northern Alps.

Those stranded include hotel guests and hikers staying at a nearby mountain hut, police said on Aug. 9.
