Teradomari coastal hot spring delicious exploration of inn Sumiyoshiya

Sumiyoshiya is a seaside ryokan on the Teradomari coast with two separate baths: a second-floor indoor bath filled with the inn's onsen water, and a fifth-floor hinoki (cypress) rotenburo overlooking the fishing port and the Sea of Japan, though its water is heated rather than drawn from the spring. The sunset from that outdoor bath, when the sea turns red, is a highlight. A reservation-only private sauna with its own cold plunge runs separately, and the annex, Bettei Yunagi, has a paid family bath. The building shows its age but is kept clean, and the seafood dinner, crab and sashimi built around local fish, gets more praise than the facilities.
