History
On July 16, 2009, eight members of an adventure tour group on a 4-day hiking trek died of hypothermia in bad weather on Mount Tomuraushi. Five others from the group were helicoptered to safety. The victims were believed to have exhausted themselves in strong winds and rain in an area with few mountain lodges. Police investigated the possibility of professional negligence of the climbing tour operators and guides leading to the deaths. On the same day, another climber died on nearby Mount Biei. The next day a lone hiker was found dead on Mount Tomuraushi.
