Best ryokan in Hakone: 10 inns compared on onsen, food and price

Gora Hanaougi is the most reliable choice: all 20 rooms have an open-air bath of the inn's own faintly reddish spring, about 49°C, and the room baths are free-flowing, so you can add cold water yourself. It scores 4.69 across 58 reviews, 4.79 across 335 and 4.6 across 879 on three major sites, guests praise the barefoot tatami corridors and warm staff, and its FAQ says guests with tattoos may use the large baths. The catch: rooms are compact (mostly 36㎡), some fittings are worn, and dinner is good but uneven.

Gora Kadan, a former imperial villa with three Michelin keys, is superb in its detached suites, whose open-air baths are source-fed from the inn's own springs with no added water. It scores 4.41 across 143 reviews on one leading site, with the baths highest at 4.60, and plans with two meals start from about ¥132,000 for two. But about a quarter of 32 reviews posted from April to September 2026 scored 3.5 or below, citing cleaning lapses in ageing standard rooms, and it is unclear whether standard rooms' baths use spring water — ask when booking.

Hakone Ginyu, famously hard to book (by phone, a year ahead), gives all 20 rooms a terrace and an open-air bath hanging over the Hayakawa gorge. The view is the point: the inn's own data shows the room baths are recirculated, heated and disinfected. It scores 4.36 across 72 reviews on one leading site (baths 4.67) and costs about ¥42,500–66,700 per person with two meals, but several 2026 guests reported 20–30-minute check-in waits, musty smells, worn furniture and a slimy room-bath floor.

Fukuzumiro, a three-storey Meiji-era timber inn of 17 rooms in Tonosawa, is a registered Tangible Cultural Property where Natsume Soseki and Yasunari Kawabata stayed. It shows 5.00 across 70 reviews on one major booking site; guests love the in-room kaiseki, the Omaru-buro (a round red-pine tub about two metres across) and free private baths, and the inn has no tattoo restrictions. Weekday stays run about ¥31,000–42,000 per person with two meals. Know the trade-offs: only one room has its own bath and toilet, the shared toilets aren't separated by gender, there's no lift, winter draughts make it cold and the river can be loud.

Gora Kansuiro is a Taishō-era Mitsubishi family villa where Emperor Shōwa stayed in 1955, set in a large garden with two wells of its own; nine of its 14 rooms have their own spring-water bath. It scores 4.47 across 427 reviews on one major site, though many 2026 reviews came through a plan offering ¥10,000 off for posting one, and rates run about ¥31,000–56,000 per person with two meals. It is genuinely old: the cheaper, bath-less rooms can be draughty, and there are steps everywhere.

Hakone Kowakien Mikawaya Ryokan opened in 1883, has a cultural-property main building and a 16,000㎡ garden of about 30,000 azaleas that bloom from late April to mid-May. It scores 4.2 across 63 reviews on one major site and 4.4 across 47 on another, and two-meal stays in 2026 ran about ¥24,000–30,000+ per person. Book one of its rooms with a private open-air bath: bath-less twins, lukewarm baths, crowded check-ins and a 40-minute breakfast wait in 2026 are the recurring complaints.

Tonosawa Ichinoyu Honkan, a wooden inn founded in 1630 and run on budget lines by the Ichinoyu group, is the cheapest stay here: Rakuten lists two-meal plans at about ¥13,200–39,700 per person for two sharing. You lay your own futon, but soft drinks and alcohol are free, and dinner — Yonezawa beef shabu-shabu and a whole simmered kinmedai — scores 4.6 within a 4.3 rating across 1,018 reviews on one major site. Some rooms have their own free-flowing bath; many others have no bath or toilet. There's no lift, the stairs are steep, the shared baths are small with no showers, and a June 2026 guest found cobwebs and dust.

Hakone Kowakudani Onsen Mizunoto (Kyoritsu Resort), an 87-room inn opened in 2006, costs about ¥18,000 to over ¥30,000 per person with two meals and adds two different springs, three free private garden baths and a stream of extras up to late-night ramen. It scores 4.4 across 6,577 reviews on one major site, with baths at 4.7. Service is the weak point (4.09 on another site): fixed dinner slots can be gone at check-in, plates were cleared mid-meal, and only room types named 'onsen' have spring water in the room bath. It's a steep 15-minute walk from Kowakudani Station, with a free shuttle from 14:00 to 17:00.

Hakone Yumoto Onsen Yoshiike Ryokan is a 7-minute walk from Hakone-Yumoto Station, about 85 minutes from Shinjuku by Odakyu Romancecar. Its 64 rooms wrap around a 33,000㎡ garden on a former Mitsubishi family villa, with fireflies in June, a free-drinks lounge and a free summer pool. The inn owns six springs and says every bath is free-flowing, except the terrace tubs of its Hollywood Twin rooms. It scores 4.5 across 1,179 reviews on one major site (baths 4.7), at about ¥22,000–30,000 per person with two meals. The catch: the Sansō wing is dated and partly under renovation until January 2027, a 'garden-side' room may look only at roofs, and the dining room is busy.

KAI Hakone, Hoshino Resorts' inn on the old Tōkaidō road about 7 minutes by car from the station (no pick-up), reopened in August 2025: all 34 rooms face the river and are fitted with yosegi marquetry, and there's a free teahouse and a 40-minute yosegi craft class. It scores 4.4 across 52 reviews on one major site, with rooms at 4.7 but the bath lowest at 4.2. The water is the weak point: each side has a single roofed open-air tub of heated, chlorinated water and no indoor bath, two 2026 reviewers complained of a strong chlorine smell, and standard rooms have only a shower.

If what's in the tub matters most, start with Fukuzumiro: its alkaline Yumoto No. 37 spring is cooled with natural spring water and flows continuously, and a blogger reports no reheating, recirculation or disinfection. Gora Kansuiro's outdoor baths take a spring straight from a well beside them, cooled naturally and 100% free-flowing, though the water is disinfected. Gora Hanaougi's room baths are free-flowing, and Yoshiike says all its baths are.

Be more careful elsewhere. Hakone Ginyu's room baths are recirculated, KAI Hakone's shared tubs are heated and chlorinated, one booking site lists Mizunoto's Kowakudani water as recirculated and filtered, and Mikawaya's 'free-flowing everywhere' claim conflicts with a booking site that lists its water as diluted and recirculated — confirm with the inn.

For your own free-flowing open-air bath, book Gora Hanaougi, or a source-fed suite at Gora Kadan if the budget allows. For a museum-piece inn with in-room kaiseki, Fukuzumiro; for a villa and garden, Gora Kansuiro or Yoshiike. On a budget, Ichinoyu Honkan for food and free drinks, Mizunoto for baths and extras. KAI Hakone suits a design-led stay where the bath matters less, and Hakone Ginyu is for the gorge view rather than the water. Whichever you pick, check the exact room type: in Hakone, the private bath, the toilet and even the onsen water often come only with certain rooms.
