Japanese Guest Consensus

A Gero inn founded in 1804 with seven riverside private baths, renovated rooms with their own onsen tubs and a menu of A5 Hida-beef kaiseki — but the big baths don't swap, breakfast is now half-buffet, the private baths cost extra and 2026 reviews are split on the food

Yamagataya traces its founding to 1804 (Bunka 1): its founder, 'Gero Yamagata-ya Iemon', appears in the Naniwa-kō register, an Edo-period list of inns that Osaka merchants judged safe to stay at. Today it's an 89-room house in three linked buildings on the Hida river — the old Roshōkan, the Tōsenkaku and the 11-storey Daikansō — a minute or two on foot from the heart of the onsen town. Recent investment shows: suites with semi-open-air onsen baths opened in March 2022, the Roshōkan's 15 rooms were redone in 2024 (six with an onsen bath), and five of the seven bookable riverside open-air baths were completed in December 2025. Independent write-ups are thin — one detailed blog post by a food-and-travel blogger, published in April 2026, is the main first-hand account — so most recent evidence comes from booking-site reviews. Japanese guests rate it 4.2 across 1,947 reviews on one major site (baths 4.3, breakfast 3.9) and 4.12 across 2,184 on another (baths 4.30). Guests in 2026 praise the silky alkaline water, the renovated rooms with onsen tubs, river and fireworks views, warm staff who stage birthday and anniversary surprises, and the free shuttle and walkable location. The complaints, also from 2025–2026: the large bath and open-air bath don't swap between sexes, so you get the same one all stay; a half-buffet breakfast some found ordinary or slow; dinners that some found tough, oily, lukewarm or smaller than before; a special room whose bath wasn't onsen and smelled musty; private baths now ¥4,400–5,500 per 45 minutes; and long waits to be shown to rooms. Two-meal stays in 2026 reviews ran about ¥14,000–30,000+ per person.

Room Selection Guide

Recommended

  • Roshōkan Japanese-Western rooms with an onsen bath (renovated 2024)

    The oldest building, closest to the sound of the river, with cherry trees outside: twin beds plus a tatami corner for up to four, and an indoor bath piped with Gero's hot-spring water. These are the rooms 2026 reviewers rave about most — an August 2026 guest bathed four times, a September 2026 guest called the in-room water 'torotoro' (silky-thick), and an October 2026 family booked one for grandparents who found the big baths hard to reach. One April 2026 guest found the tub's high rim hard to climb into. The cheaper twins in the same building have a rain-shower booth instead of a bath.

  • Tōsenkaku rooms with an onsen bath — the open-air-bath rooms (Kaze no Izanai, Kawa no Seseragi, Tsuki no Katarai) and the Momose/Chihako suites

    Three retro-modern rooms each have a terrace open-air bath — Shigaraki ceramic, an old iron cauldron or cast iron — with meals in a private dining room; an October 2026 couple in Kawa no Seseragi called the view, food and bath superb. Momose and Chihako (opened March 2022) are about 70㎡ suites with a semi-open-air onsen bath looking over the Hida river and dinner served in the room. The corner room Ariake also has a semi-open-air onsen bath; its connecting twin Akebono does not — its bath isn't onsen.

Request To Avoid

  • Daikansō Western singles and twins, and the top-floor special rooms

    The 10㎡ singles have a toilet but no bath and a high window with no view — fine for sleeping, said 2026 solo guests, but tight. The 18㎡ twins and doubles are business-hotel style with unit baths, and Western rooms don't face the river; an April 2026 guest in a road-side twin couldn't sleep for traffic noise. A May 2026 guest who upgraded to a top-floor special room found its bath wasn't onsen and smelled musty, and dinner wasn't served in the room. Daikansō's two lifts are being replaced one at a time from 24 November to 17 December 2026.

Dining Deep Dive

Breakfast Consensus

3.8/5

Now a half-buffet: hoba-miso and a few Japanese dishes come on a tray, with side dishes, eggs, bread and drinks from a buffet (a set Japanese meal at New Year and special periods). A blogger who stayed before the change loved the set breakfast; 2026 reviewers were split — some praised the hoba-miso and the volume, others found little variety, queues for rice with two seatings, crowded tables in a large hall, or were surprised by a buffet they hadn't expected

Ask for the free station shuttle at check-in: the bus meets set limited-express arrivals, and at other set times the Hida Taxi rank at Gero Station will bring you to the inn free (and take you back on departure, booked in advance). If you drive, staff valet-park your car — sometimes in an off-site lot — and fetching it can take 5–30 minutes when you leave.

Dinner Insights

3.9/5

Kaiseki built on local produce and fish sent daily from the market, from the standard Kōfuku kaiseki to a version where each person picks an A5 Hida-beef main (ceramic-plate grill, hoba-miso, shabu-shabu or sukiyaki with an onsen egg), the Hida Bishoku kaiseki and the six-dish A5 Hida Beef Zanmai; extra Hida beef costs ¥3,850 a dish. Where you eat — your room, a private room or a dining hall — is the inn's choice unless your room or plan guarantees it (couple, baby and anniversary plans, the open-air-bath rooms and suites). A blogger writing in 2026 was delighted by very fresh sashimi and Hida beef cooked at the table, and many reviewers call the portions generous. But other 2025–2026 reviewers found the standard plan's sukiyaki beef tough, the Hida beef oily, dishes lukewarm or slow, and quality and volume down on earlier visits. Last dinner start is 19:30.

Onsen & Wellness Realities

Water Type

Gero's alkaline simple spring (pH 9.1, 55.6°C), clear and smooth, supplied from the town's shared co-operative tank. The inn states its baths are free-flowing combined with partial recirculation, with water added when the tubs are refilled, partial reheating to hold the temperature, and chlorine disinfection; tubs are fully drained at least every seven days. A free hand-bath of untreated source water sits beside the entrance.

Privacy & Atmosphere

One large indoor bath and one open-air bath among bamboo and maples above the Hida river, open 15:00–1:00 and 5:00–9:30; the inn has no sauna, and the baths do not swap between sexes, which some 2026 guests found dull. Seven bookable open-air private baths line the river — the big Tamayura (¥5,500 per 45 minutes) and six smaller ones in ceramic, stone or wood (¥4,400); five opened in December 2025. Soap and shampoo can't be used in them. An April 2026 guest noted the price had roughly doubled, and a January 2026 guest found the water too cool. Free ice lollies wait after your bath.

Tattoo Policy

Guests with tattoos of any size or placement — stickers included — may not use the large bath or open-air bath, according to the official site. No policy is stated for the private baths — contact the inn.

Local Warnings & Nuances

  1. 01

    Check-in 15:00, check-out 10:00 (11:00 on some plans) — and the large baths close at 9:30 in the morning.

  2. 02

    The three buildings are linked by corridors and lifts; staff walk you through the layout, but an August 2026 guest still got a little lost, and some 2026 guests waited a long time after check-in to be shown to their room.

  3. 03

    Food allergies must be notified in advance; the kitchen can't remove stocks or trace ingredients, so the inn cannot cater to severe allergies.

  4. 04

    Air-conditioning is switched over by season: a May 2026 guest was told cooling only starts in June and had a hot night in a room without window screens.

  5. 05

    Fireworks over the Hida river in summer and winter are visible from many river-side rooms — ask about the schedule at check-in, as one January 2026 guest wished they'd been told.
