仙石高原大箱根一の湯
(せんごくこうげんだいはこねいちのゆ)
176. Sengokukogen Daihakoneichinoyu, Hakone Day-use bathing should be 1400 with a towel set + the receipt lets you visit other Ichinoyu locations in Hakone for free that same day (I got into this one for free using the receipt). Day-use hours are 13:00 to 20:00. Based on a sign — it's a dog-friendly place. Location isn't very convenient. One indoor bath. Clear water, hot+ temperature. Good air inside. Worth visiting if you're doing the Ichinoyu receipt run or happen to be right next to it. Otherwise can be skipped.
