Saitama prefecture rescue fees (2018)
Saitama became Japan's first prefecture to charge climbers for helicopter rescues in designated mountain zones after a 2017 rescue helicopter crash killed five crew members. The fee runs about 8,000 yen per five minutes of flight time.
Mountain accidents in Saitama fell from 52 to 34 over seven years, and 38 rescues were billed by March 2026.
The fee model became Japan's template for shifting mountain rescue costs from taxpayers to climbers.
Yamanashi's fee schedule, structure, and justification mirror Saitama's system almost exactly, making it the direct precedent for this policy.
