Isumi Onsen Chiba

Isumi, on the Pacific coast of the southern Boso Peninsula in Chiba Prefecture, is celebrated for its wild primrose and flower meadows that bloom spectacularly each spring, and for the scenic Isumi Railway whose bright yellow trains wind through rice paddies and coastal bamboo hills between the Pacific port of Ohara and the inland mountains. Isumi Onsen Chiba draws on chloride-rich coastal thermal waters from the marine geological formations of the Boso Peninsula's outer Pacific coast, providing warm maritime baths in a pleasantly rural setting of coastal farmland and subtropical vegetation characteristic of the southern Chiba countryside. The wild lotus primrose blooms, the Isumi River cycling routes, the fresh tuna sashimi of Ohara port, and the scenic coastal railway that has become a beloved photography subject make Isumi a charmingly seasonal spa destination on the Pacific coast of Chiba.
