四万温泉には無料で入れる公共浴場が3か所あります。どこも趣がありますが、アクセスがいいのはこの河原の湯です。温度も少しあつめでちょうどいい。外部の入浴は9時〜15時までですが、地元の方に感謝です。
There are three public bathhouses, which open for the public. All of them are nostalgic, and this riverside spa has the best accessibility. Temperature is a bit high, but it's perfect hits for me. Non-residense use is from 9 am to 3 pm, and I would really appreciate the residence people.
