Higashiyama Onsen Miyagi is a peaceful mountain hot spring in Kurihara city, situated in the northern part of Miyagi Prefecture in forested hill country between the Kitakami and Oshika mountain ranges — a region whose valleys and river gorges are known for mushroom gathering, mountain vegetable cuisine (sansai ryori), and the slow agricultural rhythms of inland Tohoku life. The siliceous thermal waters provide skin-softening warmth, associated with well-being within a long onsen tradition, offering a genuinely unhurried rural experience in a city whose cultural landscape centers on rice cultivation, traditional festivals, and the distinctive food culture of northern Miyagi. The surrounding woodland hills, especially beautiful during spring cherry blossoms and autumn foliage, give the onsen an accessible yet authentically rural character.
Insider tip — Higashiyama Onsen in Miyagi Prefecture taps a clear bicarbonate spring rising at 40°C from the rolling hills east of the Kitakami Mountains. The waters are known for their smooth texture on skin, a hallmark of alkaline springs in the Tohoku region. Small family-run facilities dominate here, offering an intimate alternative to the larger onsen resorts of nearby Naruko. The dense mixed woodland surrounding the baths turns vivid orange and crimson each October.
