Bottom line: Yukai Resort (湯快リゾート) was merged into the Ooedo Onsen Monogatari (大江戸温泉物語) brand on November 1, 2024, and every property was renamed to one of four names: Ooedo Onsen Monogatari, Ooedo Onsen Monogatari Premium, Ooedo Onsen Monogatari Wanwan Resort, or TAOYA. The operating companies followed on September 1, 2025, when Ooedo Onsen Monogatari Hotels & Resorts and Yukai Resort were combined under GENSEN HOLDINGS Co., Ltd. The former Yukai Resort official site (yukai-r.jp) now redirects automatically to the Ooedo Onsen Monogatari Group official site (ooedoonsen.jp), and reservations run through that single channel. Most of the inns kept their own names, such as Saichoraku (彩朝楽), Seiunkaku (青雲閣) and Saiki Bekkan (斉木別館), so searching by the inn’s own name will find the place you used to visit.

How the Merger Unfolded — What Changed and When
The merger came in two stages. The two companies first formed a group on April 1, 2024, and a press release on September 2 of that year announced a brand merger on November 1, 2024. At the time of the announcement, Ooedo Onsen Monogatari had 35 onsen inns plus 2 bathing and theme-park facilities, and Yukai Resort had 29 onsen inns, making 66 facilities in total under the Ooedo Onsen Monogatari Group. Then, on September 1, 2025, the two operating companies were merged into GENSEN HOLDINGS Co., Ltd. (71 properties nationwide at the time of the merger; President and Representative Director Shunsuke Kawasaki).

Old Name to Current Name — How to Find Your Regular Inn
The group’s official releases spell out a former Yukai Resort name for the following four properties, each of which was renovated or rebranded alongside the brand merger. In all four cases the name of the building itself changed, so searching by the old name returns nothing.
| Old name (Yukai Resort era) | Current name | Location | Switch date |
|---|---|---|---|
| Yukai Resort Premium Hotel Senjo (湯快リゾートプレミアム ホテル千畳) | TAOYA Shirahama Senjo (TAOYA白浜千畳) | Shirahama Onsen, Wakayama | November 1, 2024 (rebrand opening) |

For the other former Yukai Resort inns, the usual pattern is that the Yukai Resort or Yukai Resort Premium prefix was replaced by Ooedo Onsen Monogatari or Ooedo Onsen Monogatari Premium, while the inn’s own name stayed exactly as it was. Picking the former Yukai Resort inns out of the official site’s property list (76 properties as of October 4, 2026) by onsen area gives the table below. Search the official site by the inn’s own name (Saichoraku, Seiunkaku, Saiki Bekkan and so on) or by onsen area and you will reach your regular inn.

The Four Brands and What They Actually Cost
After the merger the inns fall into four series. In the official definitions, Ooedo Onsen Monogatari is the standard line, Ooedo Onsen Monogatari Premium is the premium line, Ooedo Onsen Monogatari Wanwan Resort is for guests travelling with dogs, and TAOYA is an all-inclusive onsen resort hotel built around a concept of relaxed, graceful stays. For former Yukai Resort regulars, a workable rule of thumb is: Standard is close to the old Yukai Resort in price and style of stay, Premium corresponds to the old Yukai Resort Premium, and TAOYA is the upper series where drinks and lounge access are included in the rate. For more on the spread of rates that bundle free-flowing drinks and lounge access, see All-Inclusive Japan 2026: Free Drinks, Lounges & the +40.7% Meal Lift.
So what does a stay actually cost? For the former Yukai Resort inns, we took OTA listed prices (as of October 4, 2026; per room for 2 guests, tax included) and lined up the cheapest plan on each date for a November weekday (Wednesday the 11th) and a Saturday (the 14th). Meal terms differ from plan to plan among the cheapest plans, so bear in mind that the actual price with dinner and breakfast at the same inn will be higher than these figures.
| Brand | Inn | Weekday low (Nov 11) | Saturday low (Nov 14) |
|---|---|---|---|
| Standard | Yamashiro Saichoraku | ¥22,800 | ¥36,600 |
| Standard | Yamanaka Saichoraku | ¥22,200 | ¥40,000 |
| Standard | Awazu Grand Hotel | ¥25,600 | ¥51,600 |
| Standard | Gero Bekkan | ¥31,600 | ¥59,400 |
| Standard | Terunoyu | ¥28,800 | ¥43,600 |
| Standard | Unzen Toyokan | ¥29,000 | ¥44,200 |
| Premium | Kaga Maruya | ¥28,000 | ¥46,400 |
| Premium | Yamanaka Grand Hotel | ¥33,600 | ¥49,800 |
| Premium | Seiunkaku | ¥31,600 | ¥73,200 |
| Premium | Gero Honkan | ¥46,800 | ¥84,800 |
| Premium | Shirahama Gyoen | ¥27,200 | ¥51,000 |
| Premium | Saiki Bekkan | ¥53,600 | ¥77,400 |
| Wanwan Resort | Yataya Shotoen | ¥48,000 | ¥72,600 |
| TAOYA | TAOYA Wakura | ¥55,000 | ¥83,400 |
| TAOYA | TAOYA Shirahama Senjo | ¥40,400 | ¥65,200 |
| TAOYA | TAOYA Nachikatsuura | ¥61,000 | ¥73,200 |
Source: OTA listed prices (as of October 4, 2026; stays on November 11 and 14, 2026; per room for 2 guests, tax included; cheapest listed plan on each date), compiled by the HotelBank Editorial Team. Prices change daily.
Three things stand out. First, Standard weekdays are listed from the ¥22,000–31,000 range per room for 2 guests, or roughly ¥11,000–16,000 per person, so compared with Premium and TAOYA the old Yukai Resort price band of an easygoing onsen trip is still there. Second, Premium weekdays span a wide ¥27,000–53,000 range, and inns differ even within the same Kaga Onsen area, as with Kaga Maruya (¥28,000) and Yamanaka Grand Hotel (¥33,600). Third, TAOYA starts in the ¥40,000 range even on weekdays, a step higher in line with its all-inclusive drinks and lounge access. Saturdays run at roughly 1.5 to 2 times the weekday price (1.2 to 2.3 times across these 16 inns), so the shortcut to an inexpensive Yukai Resort-style stay is to combine a weekday with an early booking.
Reputation After the Merger — Strengths Seen in 270,000 Reviews
Guest reviews are the quickest way to check what happened to the substance once the name changed. Across 271,847 guest reviews of 61 Ooedo Onsen Monogatari Group properties compiled by the HotelBank Editorial Team (last 24 months, as of October 1, 2026), the overall rating averages 3.95 out of 5. By category, breakfast scores 4.09, meals 4.06, bathrooms 4.03 and staff 4.02, so ratings cluster around the three pillars the group promotes: buffet dining, hot springs and hospitality.
The pattern holds when narrowed to the former Yukai Resort inns. Among 429 reviews of Ooedo Onsen Monogatari Premium Kaga Maruya (October 2024 to September 2026), comments such as “the buffet is the best,” “the cleanliness and service are wonderful…” and “the all-you-can-drink lounge was good” stand out, while the 960 reviews of TAOYA Shirahama Senjo (same period) include “both breakfast and dinner have plenty of variety…” and “the staff were wonderful to deal with as well…”. At the Standard-brand Ooedo Onsen Monogatari Yamashiro Saichoraku (365 reviews, same period), “a spacious room and a great buffet” and “the staff are helpful” also rank near the top. The all-you-can-eat dining and unpretentious service that regulars valued in the Yukai Resort days appear to remain at the core of these inns after the merger.

How to Book — Your Old Bookmark Still Works
There are three ways in. The first is the Ooedo Onsen Monogatari Group official site (ooedoonsen.jp). The former Yukai Resort official site (yukai-r.jp) redirects there automatically, so an old bookmark still gets you to the right place. The second is Iifuro membership, the membership program on the official site: there is no joining fee or annual fee, bookings made through the official site get a 10% member discount, and after a first stay members move up to Gold status with a birthday coupon (¥1,000 off). The program was introduced as a common membership for all properties at the time of the brand merger, when the commemorative Iifuro! Saiko Campaign (check-ins from November 1, 2024 to February 28, 2025) offered 15% off standard plans. The third is booking through an OTA: as the price table above shows, every former Yukai Resort inn is also listed on OTAs.
As a guide to choosing: if you simply want to stay at your regular inn, search the official site by the inn’s own name and take the 10% Iifuro member discount. If you want to try a step up in the same onsen area, pick a place where a Premium property sits in the same area, such as Yamanaka Grand Hotel in Kaga, Gero Honkan in Gero or Shirahama Gyoen in Shirahama, so you can compare without changing your journey. If you want to splurge for an anniversary or similar occasion, the candidates are the three former Yukai Resort inns that converted to the upper series: TAOYA Wakura, TAOYA Shirahama Senjo and TAOYA Nachikatsuura. In areas like the Kaga Onsen area, where long-established ryokan and Ooedo Onsen Monogatari inns stand side by side in the same hot spring town, this article reading the inns through the structure of a town built around its public bathhouse (soyu) (in Japanese) is a useful reference for choosing between them.
