In Japan, a traditional bathing ritual is deeply ingrained in the culture. This communal bathing practice, known as an onsen, is a serene and rejuvenating experience where individuals connect with nature and each other. Visitors typically begin by bathing naked, washing thoroughly, and then soaking in the warm waters, often surrounded by stunning natural scenery. This tranquil tradition emphasizes relaxation, respect for others, and a harmonious coexistence with the environment.
Insider tip — Asahi-machi in the Mogami River valley of Yamagata produces Japan's finest mountain apples — Fuji, Tsugaru, and Jonagold varieties grown in cool highland conditions that concentrate both sugar and acidity. 'Ringo Onsen' (Apple Hot Spring) celebrates this agricultural identity with direct and charming simplicity. The Mogami River flows through the valley below the orchards — Matsuo Bashō descended these waters in his epic journey through Tohoku in 1689, composing haiku as he rode the rapids through dense rain. Apple country and bashō poetry flow together in this Yamagata valley.
