About this map and how to read the numbers

In the autumn leaves season more people head into the mountains, and falls, hikers getting lost and accidents during mushroom picking become more common. This map shows mountain accidents since September 2026, one at a time, from prefectural police announcements and news reports. In 2025, 3,623 people were involved in mountain accidents in Japan, the most since records began in 1961, and in summer 2026 (July and August) 839 people were involved (preliminary figure, may be revised).
