Insider tip — Mori no Kuni Poppo Onsen is set in the wooded mountains above Uwajima in Ehime Prefecture, a castle town on Shikoku's southern coast. The simple thermal waters emerge at 40 degrees Celsius from metamorphic basement rock and flow into rustic wooden baths shaded by broadleaf forest. The facility is a community recreational centre popular with local families and school groups, offering a relaxed alternative to the formal resort onsen culture found elsewhere. Pearl-farming boats are visible in Uchiumi Bay from the hillside terrace, providing a distinctly Ehime coastal backdrop.
