Toraiwa Hot Springs (虎岩温泉, Toraiwa onsen?) is a hot springs inn that the Nakano Family and Uesugi Family visited during spring vacation.[1] The inn is owned by Nakano Quintuplets' grandfather.[2]


  • The hot springs inn is located in Himakajima, an island in Japan.[1] The island is famous for its fresh octopus. There are two octopus statues located on the east and west ports, one of which is depicted in the manga.[3] Despite this, the inn itself appears to be a fictional location.
