- Admission
- The price has two tiers, split at 15:00. Entry taken from opening until 15:00 is ¥743 for adults and ¥440 for ages 3 to elementary; entry from 15:00 onward is ¥1,073 and ¥660 (both are day passes including bathing tax). Towels printed with the hotel's name are sold for ¥275; bath towels rent for ¥220, yukata for ¥220 and blankets for ¥330. A private rest room is ¥2,200 for two hours.
- Spring water
- Ikaho's emblematic 'golden water' is a calcium-sodium sulphate-chloride spring that carries iron and turns tea-brown on contact with air. Within Ikaho it stands opposite the 'silver water', feeling soft on the skin with good heat retention. Metal jewellery can discolour, so taking it off before entering is wise.
- Baths
- There is an open-air bath looking over forest green and a bright great bath with wide windows and skylights. The rest areas are generous, with a manga corner, games, table tennis and private karaoke rooms (paid), so it is easy to pass time after bathing. Toiletries and dryers are in the great bath and included in the fee.
- Time-based pricing
- Entry after 15:00 costs ¥330 more for adults, so arriving before midday pays. Conversely, if only the evening is free, ¥1,073 lets you stay until 10 p.m. With closing at 22:00 and last entry at 21:00, it is one of the few Ikaho facilities you can enter late.
- Access & parking
- 25 minutes by Kan'etsu Kōtsū bus for Ikaho Onsen from Shibukawa Station on the JR Jōetsu Line, getting off right at 'Ikaho Grand Hotel-mae'; about 20 minutes from Shibukawa-Ikaho IC, with free parking for 250. It does sit some way from Ikaho's famous stone stairway street, so if the stairs are the focus, parking at the municipal lots and using the bus works better.

- ¥743 for adults before the 3 p.m. cutoff
The golden brown water, with the forest in view
Ikaho has two kinds of water: the tea-brown 'golden water' and the clear 'silver water'. Kogane-no-Yukan is a day-bathing facility using the golden water, attached to Ikaho Grand Hotel. The iron-bearing water deepens in colour on contact with air, leaving its trace along the edges of the bath. The baths comprise an open-air tub looking over forest green and a bright great bath with skylights, giving an openness different from the communal baths on the stone stairway street. Arriving in the morning means ¥743 for adults, making it the easiest place in Ikaho to try the golden water.
How the price changes at 15:00
The fee here splits at 15:00. Entry taken between opening at 10:00 and 15:00 is ¥743 for adults and ¥440 for children; from 15:00 it is ¥1,073 and ¥660. Both are day passes including bathing tax, so once in you can stay until closing. That means ¥330 can be saved by moving in the daytime, or, if only the evening is free, you can use the baths until 22:00. Towels are sold for ¥275 and bath towels rented for ¥220, so travelling light is easy.
Using it as a base apart from the stone-step street
Ikaho brings to mind its 365 stone steps and the onsen buns sold along them. Kogane-no-Yukan sits a little away from that stairway street, among the hotels, which splits how people use it. If the trip centres on walking the stairs and visiting the lane-side communal baths, the municipal car parks are handier; if you arrive by car or bus and want one large place to relax, this facility suits. With free parking for 250, generous rest areas, a manga corner and table tennis, it is especially easy for families with children. It is closed the second Wednesday (the next day if a holiday).

Sainokawara Open-Air Bath
A 10-minute walk west of Kusatsu's Yubatake, at the far end of Sainokawara Park, lies one of Japan's largest open-air baths. Around 500 m² of pool brims with strongly acidic water, open to the surrounding forest. Snow in winter, fresh green in summer, illuminations at night. There are no washing stations — this is purely for soaking.
Otakinoyu
A large day facility where you can try Kusatsu's traditional 'awase-yu' — a row of wooden tubs at rising temperatures, entered in order. Indoor baths, rotenburo, sauna, plus rest and dining areas make it good for half a day. About 10 minutes' walk from the Yubatake, or a short bus ride. Admission ¥1,200 (2026); three-bath pass with Gozanoyu and Sainokawara ¥2,100.
Gozanoyu
Right in front of the Yubatake, a wooden recreation of the Edo–Meiji communal baths. Wood and stone bath halls alternate between men and women daily, with two sources (Yubatake and Bandaiko). The upstairs hall looks down on the Yubatake.
