¥500 for adults, ¥300 for elementary-school age and under (cash only). Day-use bathing is restricted to holders of the local 'Myoko Shichigosan hot-spring guidebook' and is not offered on weekends, public holidays, Obon, or New Year; it is also frequently suspended for maintenance, call ahead to confirm. A 2025 Google reviewer was admitted from 15:30 by phone arrangement, earlier than the listed 16:00 opening, so actual hours may flex by arrangement.

About
Toma Ryokan (遠間旅館) is a family-run inn in Akakura Onsen. The separate indoor baths for men and women run natural spring water straight from the source without recirculation, mild and clear without a heavy sulfur edge. Guests mention the inn's ties to the Meiji-era art figure Okakura Tenshin (岡倉天心), and it is run today by a family known for attentive, personal hospitality. The owner holds an onsen sommelier qualification.
