Overview
Hirayama Onsen Hotaru no Nagaya is a ryokan in the Hirayama Onsen area of Yamaga, Kumamoto, where all 5 guest units are detached, standalone buildings. There is no communal bath. Instead, every one of the 5 units has its own bath of 100% free-flowing onsen water straight from the source, so your family can bathe privately. Dinner and breakfast are both served in your room, but if you stay in one of the detached houses with an onsen bath (Ashi no Ho, Hanabishi or Mizuaoi) with 3 or more guests, meals are served in the dining area. The largest unit, Ui no Okuyama, is 70 sq m and sleeps up to 7 guests. Children's rates are set, but there is no published information about kids' menus or baby items. Food allergies cannot be accommodated.
Rooms
All 5 guest units are detached, standalone buildings: 2 special rooms with an open-air bath, and 3 detached houses with an onsen bath (Ashi no Ho, Hanabishi and Mizuaoi). The largest, Ui no Okuyama, is 70 sq m and sleeps up to 7 guests. It has a Western-style living room with sunken-floor (horigotatsu) seating, plus Japanese-style tatami rooms of 8 and 6 tatami mats. Rashu is 40 sq m, laid out with a Western-style living room with sunken-floor seating and an 8-tatami-mat Japanese-style tatami room, and takes 2 to 3 guests. Hanabishi and Mizuaoi are 45 sq m Japanese-Western rooms for up to 4 guests, each with a twin bedroom plus a 4.5-tatami-mat Japanese-style tatami room. When 3 or more guests stay in Hanabishi or Mizuaoi, 2 sleep in the beds and the others on futons. Ashi no Ho is a 50 sq m maisonette, with a living room and a standing-depth onsen bath on the first floor and a twin bedroom on the second floor. When 3 guests stay in Ashi no Ho, one sleeps on a futon. Rakuten Travel gives Ashi no Ho's capacity as 3 guests, while the ryokan's own room information says both "for 2 guests only" and "2 to 3 guests", which do not match, so if you plan to stay there with 3 guests, please confirm when booking. All 5 units have an air purifier with a humidifying function, a refrigerator and an electric hot-water kettle, and free Wi-Fi is available.
Dining
Dinner and breakfast are both in-room dining, and you can also ask to eat in a separate room. If you book one of the detached houses with an onsen bath (Ashi no Ho, Hanabishi or Mizuaoi) for 3 or more guests, in-room dining is not possible and meals are served in the dining area. Dinner starts at 6 p.m. and breakfast at 8:30 a.m. The food is creative cuisine made with local Kumamoto ingredients: a course that changes every month, with the owner, a woman, handling everything herself from planning the menu to cooking and plating. Because the menu changes monthly, food allergies and taste preferences cannot be accommodated. Bringing in outside food and drink is prohibited; the only exception is meals for people with allergies. There is no published information about a kids' menu or children's chairs, so if you need them, please confirm when booking.
Baths and Onsen
There is no communal bath. Instead, every one of the 5 units has its own bath of Hirayama Onsen water, 100% free-flowing straight from the source. The in-room baths are private, so your family can bathe on your own whenever you like. Ui no Okuyama and Rashu each have two tubs: an in-room open-air bath and an indoor onsen bath. Rashu's open-air bath comes with a table; it is smaller than the one at Ui no Okuyama, but big enough for 3 to 4 people at a time. According to the property news on Rakuten Travel, the in-room open-air bath at Ui no Okuyama was renovated from a rock bath into a hinoki (Japanese cypress) bath in August 2026. Ashi no Ho, Hanabishi and Mizuaoi have no open-air bath, only an indoor onsen bath. For day visitors, the ryokan offers private-hire onsen use (60 minutes of bathing at 2,000 yen per person, with the bathing tax charged separately), and notes that it may turn visitors away depending on overnight bookings. Rakuten Travel's property description says that the private-hire bath on the grounds is for outside visitors only, and that overnight guests can also use it free of charge when it is not in use (no reservations). The ryokan's own website, however, says nothing about use by overnight guests, so please check with the ryokan on the day whether you can use it. The water is an alkaline simple sulfur spring, and accessories may discolor unless you take them off. There is no published information on whether children who are not yet out of diapers (not yet toilet-trained) can get into the tubs, so please confirm when booking.
Family-Friendly Features
Children's rates are set, but the age categories and amounts are not listed in our information, so please confirm when booking. If you are traveling with children, enter each child's age and gender and the number of children in the remarks field when you book. Ashi no Ho is a maisonette with steep stairs, and families with children stay there on the understanding that this is the case. Part of Ashi no Ho's tub is a standing bath 120 cm deep, so take care with the depth when bathing with young children. There is no published information on cribs, baby futons or co-sleeping, so please confirm when booking. The entire building and grounds are non-smoking.
