Izumi, in the central southern Osaka Prefecture between Sakai and the Izumi highland range, is an agricultural city that takes its name from the ancient spring water sources of the Izumi Highland that have irrigated the Kawachi plain for millennia, and is known for the traditional Izumi cotton textile industry and the remarkable Tsurumi-ryokuchi Park whose Flower Expo 1990 legacy created one of Osaka's finest botanical garden landscapes. Izumi Onsen Osaka draws on sodium and bicarbonate thermal waters from the geological resources of the Izumi highland zone, providing restorative baths in an agricultural city whose Izumi Highland hiking trails, traditional textile heritage, and access to the greater Osaka Bay area create a practically located and naturally connected spa setting in the central southern Osaka Prefecture. The Izumi Highland nature park hiking trails above the Osaka plain, the traditional Izumi cotton market heritage, and the Tsurumi-ryokuchi Park botanical garden culture accessible from the greater Osaka corridor create a pleasantly varied natural and heritage backdrop for thermal wellness in central southern Osaka Prefecture.

Insider tip — Izumi Onsen draws bicarbonate spring water in the residential city of Izumi, nestled between the Izumi mountain range and the coastal lowlands of south Osaka. The water at 40 degrees Celsius is lightly alkaline with a characteristic smoothing effect on skin associated with Izumi's deep basement aquifer. The city is famous for its traditional textile dyeing workshops that have operated since the Edo period, and a textile museum visit pairs naturally with an afternoon soak. The facility includes a bamboo garden rotenburo that is particularly atmospheric after autumn rainfall.
