Noda Onsen Kisarazu

Kisarazu, on the western shore of Boso Peninsula in Chiba Prefecture directly across Tokyo Bay from Kawasaki, is connected to the Kawasaki shore by the Tokyo Bay Aqua-Line — Japan's longest underwater road tunnel topped by a mid-bay artificial island rest stop — making it both a transportation gateway and a significant commercial hub for western Boso Peninsula residents accessing central Tokyo. Noda Onsen Kisarazu draws on chloride-rich coastal thermal waters from the marine geological formations of the Tokyo Bay coastline, offering warm maritime baths in a bay-side city whose Aqua-Line connection to Kawasaki, the traditional Kisarazu Ondo festival dance, and the fresh Tokyo Bay clam harvest create a distinctive coastal spa setting in western Chiba. The Tokyo Bay Aqua-Line Umi Hotaru island rest stop above the Aqua-Line tunnel entrance, the traditional Kisarazu Port fishing culture, and the annual Kisarazu Ondo Festival celebrating the city's traditional dance and local identity create an appealingly port-city spa destination on the western Boso Peninsula coast.
