Rescue is free

Mountain rescue by the police and fire services is a free public service, and 110/119 calls are free. The financial risk is the helicopter: a private or commercial rescue flight can run to millions of yen, and Saitama Prefecture already bills about ¥8,000 per five minutes for its own rescue helicopter (police search helicopters cannot legally charge, so a billable disaster-prevention helicopter is sent instead).

Buy Japanese mountain insurance (yama-hoken) that covers helicopter rescue and search costs — a JRO (Japan Rescue Organization) membership or a Montbell short-term mountain plan is the standard, and both are cheap. Then confirm your travel insurance covers off-trail hiking and helicopter evacuation; many general policies exclude it above a set altitude.
