Nishiyama Onsen Keiunkan

PRESERVE Selected

Founded in 705 CE and run by 53 generations of one family — Guinness-certified world's oldest hotel. Deep in the Southern Alps, entirely fed by gushing own-source water with no heating or dilution.

A genuine hito pilgrimage for serious onsen connoisseurs; remote, family-held and historically loved by warlords and literati — impossible to mistake for a tourist hotel.
