Hanaingen (in full, Omame no Koyado Hanaingen, “the little bean inn”) is an 11-room inn in Kusatsu Onsen, Gunma, that the inn says is 99 steps from Yubatake. It is produced by the Kusatsu wagashi maker Seigetsudo, known for Hanaingen amanatto (sugared beans), and opened on August 26, 2016, in a renovated old ryokan with a Taisho-romantic look. Before you book, three things matter: there are four free private baths and no large bath; children of elementary-school age or younger cannot stay; and cancellation fees start one week before your stay.

The private baths at Hanaingen
The main building has no large public bath. Instead, it has four private baths, all free and without booking: if one is empty, it is yours. The inn’s access page says they can be used 24 hours a day.
| Bath | Capacity |
|---|---|
| Mame-buro (bean bath) | 2 |
| Heart bath | 2 |
| Maru-buro (round bath) | 2 |
| Ishi-buro (stone bath) | 4, a little larger and suited to families |
Capacities from the official bath page, read October 16, 2026.
What kind of water is it?
The water comes from the Yubatake source, and the inn says it is free-flowing, with no heating and no water added. The spring type listed is acidic, sulfur-containing aluminum sulfate and chloride water.
Are there public baths nearby?
The inn lists three: Gozanoyu about 1 minute on foot, Otakinoyu about 10 minutes, and the Sainokawara open-air bath about 15 minutes. Each runs on its own rules and fees.
Can I bathe with a tattoo?
The official website does not mention tattoos. The private baths are used only by your own group, but ask the inn before you book if this matters; public bathhouses set their own rules. Our tattoo and onsen guide explains what to ask.
Rooms and the Sora annex
What are the main-building rooms like?
The ten rooms are named after beans, such as Kintoki-mame, Hana-mame and Panda-mame, and range from 6 to 12 tatami mats. All are for two guests except Hana-mame, the largest, which takes four. Several are Japanese rooms with beds, and the smaller 6-mat rooms are suggested for solo travelers. Each has a TV, Wi-Fi, a washlet toilet, a sink, a refrigerator, a kettle, towels, a toothbrush and samue loungewear. The room list does not include a bath, so bathing is in the private baths.
All guest rooms are on the 2nd floor, there is no elevator, and the inn notes that, as an older building, you may hear other guests.
What is Sora?
Sora is a detached annex rented as one unit for 2 to 5 guests: 32 mats with a kitchen-dining room, living room, Western room, Japanese room and its own 24-hour private onsen from the Yubatake source, for Sora guests only. In a July 2026 notice, the inn said the Seigetsudo shop on the ground floor is being renovated, so construction noise may be heard in Sora.
Prices, children, cancellation and payment at Hanaingen
How much does a stay cost?
Main-building prices are per person for two guests, tax included: from 11,300 yen on weekdays, 16,300 yen on nights before holidays, and 20,300 yen at New Year, Golden Week and Obon. One guest alone pays 1.3 times the rate. Sora starts at 14,300 yen per person on weekdays for two. On top, Kusatsu Town charges a bathing tax of 150 yen per person per night where the basic rate is over 6,000 yen; see our onsen bathing tax guide. From November to April, the inn adds a heating fee, given in a 2016 notice as 700 yen per room (1,000 yen for Sora).
Can children stay?
No. The inn does not accept children of elementary-school age or younger, and the Sora page says the same.
What is the cancellation policy?
The inn says it charges cancellation fees from one week before arrival and, as an 11-room inn, does not waive them. The website does not give the percentages, so check them on your booking. It also says a booking may be canceled if you do not reply to the inn’s messages. See our hotel cancellation guide.
How do I pay?
A notice on the website lists Visa, Mastercard, JCB and American Express. It does not mention other methods.
Meals and sweets at Hanaingen
What is breakfast?
Breakfast is included: a Japanese set built around beans, from hana-mame to chickpeas, served in the inn’s café, Mame no Hana. Tell the staff your preferred time at check-in.
Where do I eat dinner?
Standard stays have no dinner at the inn; the website encourages guests to eat around Yubatake, where many places stay open late. The top page also lists a plan with a bento dinner and a plan with a kaiseki dinner at a kappo restaurant; their details are on the booking page. The website does not mention allergies or special diets, so ask the inn.
What does the wagashi maker add?
On arrival, guests get welcome sweets and matcha they whisk themselves; guests checking in after 18:00 may not get the sweets. Drip coffee, tea and the okami’s herb and fruit water are free during the stay, and guests get a 5 percent coupon for Seigetsudo.
Getting to Hanaingen in Kusatsu Onsen
The inn is in the center of Kusatsu Onsen, 99 steps from Yubatake and a short walk from the bus terminal. There is no pick-up service. The website’s route directions are images only, so we do not repeat them; our Kusatsu Onsen from Tokyo guide covers the trip. For drivers, there is a free parking lot next to the inn, but the inn calls it narrow and recommends public transport; in the icy season it asks for studless tires and four-wheel drive.
