Isoya, on the Sea of Japan coast of the Shiribeshi subprefecture of Hokkaido south of Iwanai, is a small coastal community in the rugged Hokkaido shoreline where traditional abalone and sea urchin diving culture, the dramatic cape geology of the Hokkaido Sea of Japan coast, and the mountain backdrop of the Nishiyama range create a remote and atmospheric fishing village setting. Isoya Onsen Hokkaido draws on chloride-rich coastal thermal waters from the marine geological formations of the Isoya Bay coast, offering warming maritime baths in a remote fishing community whose traditional abalone and sea urchin fishing culture, the rugged coastal scenery, and the isolated atmosphere of a small Hokkaido Sea of Japan fishing village create a genuinely off-the-beaten-path and authentically maritime spa experience. The traditional Isoya abalone and sea urchin fishing culture, the dramatic Hokkaido Sea of Japan coastal geology of the Shimamaki cape area, and the remote rural character of this small fishing community on the Hokkaido outer coast create an authentically isolated and refreshingly unpretentious coastal spa destination in the Shiribeshi subprefecture.
