adex Inn
8,6/10 Excellent - Based on 686 reviews
Adex Inn occupies a central spot in Noboribetsu Onsen, a short walk from the steam-swept trails of Jigokudani (Hell Valley) and within easy reach of local attractions such as the Bear Park and the Date Jidaimura historical village. Recently rebranded and refurbished, the property presents a straightforward, activity-oriented ethos with 47 Western-style guest rooms designed for comfort after outdoor excursions. Guests benefit from an onsen arrangement that includes direct access to a large public hot-spring facility across the road, making it an practical choice when searching for a ryokan with onsen in Noboribetsu for a restorative stop on a Hokkaido itinerary.
Onsen access is a defining feature: the property provides unlimited entry to the sister Grand Bath at the neighboring facility, where five distinct free-flowing springs feed multiple bathing pools. The thermal waters include sulphur and mineral-rich sources (alum, ferrous sulfate, salt and sodium), and the arrangement gives visitors both indoor and open-air bathing options without filtration, so the water can appear cloudy and carry naturally deposited yunohana. The onsen complex and the inn coordinate access so guests can use the larger communal baths and saunas; this structure suits travelers who want authentic hot-spring bathing without the need for a private onsen in-room.
Rooms are compact and practical, fitted with essentials such as flat-screen TV, fridge, shower booth and flexible storage for outdoor gear; public facilities include free Wi‑Fi, a media lounge, laundry and a dry room for equipment. The adex BAKERY & CAFE on site provides light meals and coffee, and complimentary parking is available for guests arriving by car. Check-in is handled in the afternoon to evening window with a morning check-out, and the inn’s location beside a major onsen complex makes it easy to combine a stay here with wider northern Honshu or Hokkaido plans—alternatives often compared by travelers seeking a ryokan with onsen Aomori connections on multi-stop routes.

Negative Reviews
Weak or unreliable WiFi in rooms
A number of guests reported poor WiFi reception in their rooms or unreliable connections, making internet use difficult at times.
Bathrooms small, dated or showing mold in some rooms
Several reviewers pointed out that some guest bathrooms are small, old or in need of refurbishment, with a few mentioning visible mold or dated decoration compared with the renovated lobby.
Self check‑in kiosk can be confusing
Some guests found the automated check‑in terminal tricky to use (names must match the reservation), requiring staff assistance to complete registration.
Limited late‑arrival support / no night desk
A few guests noted there is no overnight attendant, which can make very late arrival difficult if not travelling by car or without prior arrangements.
