Dogo Onsen (Ehime Pref.)
At one point during your lives, onsen-lovers and anime fans alike should make a pilgrimage to Dogo Onsen (道後温泉), located in Matsuyama, Ehime Prefecture. It’s got a history of over 3,000 years plus it’s said to be the oldest hot spring in Japan.
Its clock rings rings three times a day: 6:00 a.m., noon and 6.00 p.m… Be sure to leave before it gets dark (jk…)
