Sai, in the remote southern Shimokita Peninsula of Aomori Prefecture facing the Tsugaru Strait, is an isolated coastal community accessible only by road along the dramatic cliffed Pacific coast or by sea, whose traditional tuna fishing heritage, the nearby Wakinosawa fishing community, and the extraordinary Shimokita wilderness of primeval beech forest and dramatic coastal scenery create a genuine sense of Japanese frontier remoteness. Sai Onsen Aomori draws on chloride-rich coastal thermal waters from the marine geological formations of the Shimokita Peninsula southern coast, providing warming maritime baths in one of Honshu's most isolated coastal communities where the wild Tsugaru Strait views, the traditional fishing culture, and the profound natural quietness of this remote Aomori community create a genuinely restorative and isolated spa experience. The dramatic Tsugaru Strait coastal road scenery connecting Sai to Wakinosawa and the rest of the Shimokita Peninsula, the traditional Sai fishing harbour and coastal lifestyle, and the extraordinary Shimokita Peninsula wilderness of the Osorezan volcanic landscape and primeval beech forest above the coast create an outstandingly remote and atmospherically distinctive thermal spa destination.
