Isawa Meitōkan Itoyanagi Day Use: Is the Arashi no Yu Upgrade Worth It?
At Itoyanagi near Isawa-Onsen Station, day-use costs ¥2,200 for public baths or ¥3,300 with Arashi no Yu. Visits run in two-hour weekday windows; call first.
Checked: September 27, 2026
Itoyanagi is a three-minute walk from the south exit of Isawa-Onsen Station, so getting there without a car is unusually easy. The choice is less about access than about what you want to do once inside: spend the visit in the baths, or add time in Arashi no Yu, the hotel’s heated stone-bathing room.
What the extra ¥1,100 buys
The standard day-use ticket is ¥2,200 and includes the public baths. The ¥3,300 option adds Arashi no Yu, a change of clothes for the room and towels. Itoyanagi describes Arashi no Yu as a warm, humid space with heated medicinal stones; it is not another spring-fed pool, and the hotel’s own guidance treats it as a separate bathing activity.
If you mainly want the hotel’s alkaline simple spring, two outdoor baths, indoor bath and sauna, the lower-priced ticket already covers the main experience. The upgrade makes more sense if you actually enjoy a stone-bathing session and want to use the outdoor rest terrace afterward. The terrace was refurbished in March 2026 with reclining “totonoi” chairs and is open to day visitors when the hotel can accept them.
Plan around the two-hour windows
The Isawa Onsen Inn Association currently lists day use on weekdays from 1–3 pm or 6–8 pm. Older day-use posts on the hotel’s own site show broader hours and different rates, so call Itoyanagi before travelling and confirm the current slot and price. The hotel also warns that day visitors may be refused during the busy 3–6 pm check-in period, and sometimes for the whole day depending on occupancy. Once admitted, the stay is limited to two hours because overnight guests take priority.
That makes the afternoon and evening visits different in practice. The 1 pm slot leaves the rest of the day open, but arriving late does not guarantee extra time. At 6 pm, the bath works better as the last stop before returning to the station; there is no need to coordinate a bus afterward.
A few details worth checking first
Itoyanagi says its spring is drawn directly from the source on the property. The public bath page lists two outdoor baths—one hinoki and one stone—as well as a sauna. It does not provide a complete, pool-by-pool water-treatment breakdown, so avoid assuming that every bath has identical flow or heating conditions.
The hotel’s day-use notice excludes guests with tattoos, intoxication, or poor health. If any access or bathing rule could affect your visit, call the hotel rather than relying on older third-party listings. The public number is 055-262-3141.
You can walk from Isawa-Onsen Station in about three minutes, and the hotel also lists free parking. For a broader look at nearby options, start with the Isawa day-use onsen guide. The Hotel Sekitei day-use guide is another nearby hotel option, with different pricing and bath conditions.
