YesEntry is accepted until 9pm; the baths themselves close at 9:45pm for cleaning, ahead of the 10pm building close.
Weekday admission (junior high and up) is 990 yen, or 800 yen after 7pm; weekends and holidays it's 1,090 yen (1,050 yen after 7pm).

Open-air outdoor bath
Cold water plunge bath, typically used after sauna
Bathing Arrangements
Private bath available for day-use visitors or hotel guests to reserve
Shared bathing area for all genders
Site offers a separate reservable private-room bath specifically for couples/families wanting privacy, implying the regular indoor/outdoor baths are the standard gender-separated layout; no mixed bathing is mentioned anywhere on the site.
Policies & Services
Allows entry with visible tattoos
Welcomes children and families
General admission is priced for children (elementary and under, and infants), but ganbanyoku is officially restricted to those above elementary-school age. One 2026 review also reports being told at reception that elementary-age children are barred from the sauna, though this is not stated on the site — kept the official ganbanyoku-only restriction.
Towels available to rent or borrow
Site also sells a branded towel (販売タオル) separately at the same price; distinct line item from the rental.
Relaxation space for after bathing
On-site or nearby parking available

About
Bon no Yu is a day-use bathhouse in Chichibu, right along the Arakawa river. It has an indoor bath, an open-air rotenburo, a hot and a cool sauna, and a cold plunge, plus ganbanyoku (岩盤浴), a heated stone-bed room to lie in. The spring water itself is soft, known locally for leaving skin smooth. For more privacy there are reservable rooms with their own indoor or open-air bath, and the tatami rest area and dining hall both look out toward the river and the hills around it.
