Hanayu Spa Resort or Yuraku no Sato in Kumagaya?
Both use natural hot-spring water. Hanayu says all spring baths are free-flowing; Yuraku heats and recirculates its spring baths and is nearer Ishihara Station.
The basic weekday ticket is ¥950 at Hanayu Spa Resort and ¥880 at Kumagaya Yuraku no Sato, a ¥70 difference.
That small gap is not the useful distinction. Hanayu says all its hot-spring baths use its own water on a 100% free-flow basis; Yuraku’s named spring baths are heated and recirculated. Yuraku is also the simpler rail stop, about a 10-minute walk from Ishihara Station.
The spring comparison
| Hanayu Spa Resort | Kumagaya Yuraku no Sato | |
|---|---|---|
| Spring source | Own source, about 1,500 m underground | Source at 1,385 m underground |
| Published figures | 300 L/min used; do not read this as measured natural yield | 33.3°C source temperature; 250 L/min flow |
| Spring-bath system | Operator describes all hot-spring baths as 100% free-flowing | Rock bath, pot bath and reclining bath are heated and circulated |
| Weekday adult admission | ¥950 | ¥880 |
| Weekend/holiday adult admission | ¥1,100 | ¥980 |
| Bedrock-bath add-on | ¥800 weekdays; ¥900 weekends/holidays | ¥550, including dedicated clothing and towel |
| Rail access | Free shuttle from Kumagaya Station North Exit | About 10 minutes on foot from Ishihara Station |
Hanayu’s source is described as golden and sulfur-scented. Its headline 300 L/min figure is the amount of spring water used under the prefectural limit, not a measurement of the spring’s natural output. Yuraku publishes a conventional source analysis: simple spring, low-tonicity and weakly alkaline, with water emerging at 33.3°C. That source temperature should not be mistaken for a fixed bathing temperature.
How the add-ons change the bill
On a weekday, bathing plus Hanayu’s Onkatsu Cafe Nest course comes to ¥1,750. On weekends and public holidays it is ¥2,000. The Nest add-on includes a bedrock-bath mat and facility clothing, requires a separate bathing ticket, and is available from junior-high-school age.
Yuraku’s bedrock-bath area costs ¥550 on top of admission. That makes a weekday bath-and-bedrock visit ¥1,430, or ¥1,530 on weekends and holidays. Its dedicated clothing and towel are included in that add-on; bath towels are separate. These totals are ordinary listed prices, and both facilities may set special-date rates.
The extra spend at Hanayu makes more sense if you expect to use its bedrock rooms and stay for several hours. If your plan is simply to soak, use the sauna and head back, Yuraku has a lower entry price and less reason to turn the visit into a half-day outing.
The 2026 prices have a special-period wrinkle: Hanayu listed September 19–23 as special dates, with a five-hour limit on the base admission and a ¥500 extension fee after that. Yuraku’s operator marked September 19–27 as a Silver Week pricing period. Those dates are now past, but they show why a weekend price is not always the right budget for a holiday visit; check the live notice for your travel date.
Pick by the kind of visit you actually want
Choose Hanayu when the spring itself is the point, or when you want a garden-style bathing area followed by a longer stay in the bedrock-bath lounge. It opens 10 a.m.–11 p.m.; last admission is 10:30 p.m. The north-exit shuttle from Kumagaya is convenient, but its last return leaves at 9:30 p.m. If you intend to stay later, plan another ride back before you enter.
Yuraku suits a shorter visit and a train-first itinerary. It is open 9 a.m.–midnight, with last reception at 11:30 p.m.; from JR Kumagaya, transfer to the Chichibu Railway for Ishihara, then walk about 10 minutes. The added rail leg is predictable, and there is no facility shuttle to catch.
For a three-way look that also includes the long-stay Hareniwa lounge, see the Kumagaya day-bath overview. The practical differences between each last-mile route are in the no-car access guide.
Both facilities prohibit tattoos. Yuraku’s current rules also include tattoo stickers; Hanayu’s visitor information additionally excludes intoxicated guests and guests wearing diapers from bathing. Children using Yuraku’s baths must follow its opposite-sex bathing limit: elementary-school children, and younger children at least 120 cm tall, may not enter the bath for the opposite sex. Both facilities restrict their bedrock-bath areas to junior-high-school age and older. Check the facilities’ own notices for special dates and current entry rules.
