About this onsen
Inubosaki is the easternmost cape of the Kantō region, famous for having Japan's earliest New Year's sunrise. Its landmark, Inubosaki Lighthouse, is a Western-style lighthouse first lit in 1874. In spring 1997, the Shio-no-Yu hot spring began flowing on this cape, making Inubosaki Kanko Hotel an inn with its own source. The sodium-calcium chloride water generously fills eight baths, and the Pacific horizon spreads from the waterside open-air baths.
Good to know
Day bathing is 12:00-19:00 (leave by 20:00): 1,300 yen for adults on weekdays and 1,500 yen on weekends and holidays (children 800/900 yen; Obon, year-end/New Year, Golden Week, and 3-day weekends are priced separately). The private bath Miotsukushi requires reservation, from 4,500 yen for 2 people and 50 minutes. There are 1-2 irregular closing days per week, so confirming by phone is wise. The foot bath by the entrance is free for everyone.
