Kotohiki Kairō open-air bathhouse, Kan'onji
A Japanese-style spa right by Kotohiki Park in Kan'onji, western Kagawa — famous for the giant coin drawn in sand, the Zenigata Sunae — and directly in front of Ariake beach. Its baths are inventive: a 'seawater onsen' bath, an ancient-cypress bath and a kama-buro steam bath recreating a 1,200-year-old design (alternating men/women daily), and the open-air bath looks over the Seto Inland Sea toward the sunset. Adults ¥950 on weekdays, ¥1,100 on weekends and holidays; open 11:00–23:00 (last entry 22:00), every day of the year. A sea-view restaurant, indoor and outdoor rest areas and lodging are attached. About 5 minutes by car from JR Kan'onji Station or 15 from Sanuki-Toyonaka IC; 500 parking spaces. Combine with the Chichibugahama sunset and the sand coin.
