O-furo cafe Hareniwa no Yu, a bathhouse in Saitama operated by Onsen Dojo Co., Ltd., will host a 'Blue Sea Bath' event from May 11, inspired by the sea of Ishigaki Island. As part of their 'Ishigaki Fair,' the bath will feature 'nigari' (bittern), a byproduct of salt from Ishigaki, allowing visitors in the landlocked prefecture to experience the blessings of the sea.
