NIJISANJI x Gokurakuyu “Totonou Nijisanji” Returns for a Fourth Run: Nov 12 to Dec 8 at 39 Bathhouses

The bathhouse chain Gokurakuyu and its RAKU SPA sister brand will hold the fourth edition of their NIJISANJI tie-up, “Totonou Nijisanji,” from Thursday, November 12 to Tuesday, December 8, 2026. The operator, Gokurakuyu Holdings, issued the announcement on October 22, 2026. As in earlier years the campaign mixes character goods, themed food and drinks, newly recorded in-store announcements and, the part that gives the series its identity, collab baths scented to match the featured talents.

At a glance

• Dates: November 12 to December 8, 2026 (Thursday to Tuesday).

What is on offer

The entry-level item is the “Totonou Nijisanji Plus Set.” According to the campaign page it is listed at 1,100 yen (tax included) on top of admission, and buyers receive a collab towel of roughly 200 x 800 mm in one of eight random designs, limited to one per visit. Since the price is described tersely on the page, confirm the exact wording at your branch.

Goods follow the pattern of previous years. The press release lists full-body acrylic stands at 1,650 yen each in eight designs, trading keychains at 880 yen each in two random groups (full-body or mini-character art), a two-piece hexagonal can badge set at 1,540 yen, a canned chocolate crunch at 2,090 yen and a jacquard bath towel at 4,400 yen. Online only are the “Mochikororin” plush mascots at 1,375 yen each and complete keychain sets at 3,520 yen. Spending in store also earns extras: a random postcard for every 2,000 yen, and a lottery ticket for decorations such as banners and tapestries for every 5,000 yen. According to the campaign page, lottery results are due on December 28, with prize pickup from December 28 to January 31. Plus Set and online purchases do not count toward these perks, and separate receipts cannot be combined.

On the menu side there are eight drinks at 880 yen each, one per featured talent, and six food and dessert items: parfaits, noodles, a Chinese-style set, a coffee jelly parfait, a pizza and a spicy chicken omurice for Oriens, priced from 1,650 to 2,200 yen. Every order comes with a random coaster, and the campaign page says there are 16 coaster designs.

The collab baths

Five themed baths run on staggered dates, each pairing a scent with a talent or duo:

• NIJISANJI bath (floral musk): November 12 to 15.
• Ishigami Nozomi and Kuramochi Meru (geranium): November 19 to 23.
• Inui Toko and Runrun (healing aroma): November 25 to 28.
• Akagi Wen and Saeki Itetsu (herbal): November 29 to December 2.
• Usami Riito and Hiyaku Mana (mugwort): December 5 to 8.

Each bath also has its own X-campaign day. Visitors who follow the official account, post about the collab with the hashtag #ととのうにじさんじ and show the post at reception can receive a limited postcard on a first-come basis, with the first-come dates matching the bath start dates (November 12, 19, 25, 29 and December 5), according to the press release.

Background: three earlier runs

The series began on November 1, 2023, with eight NIJISANJI talents at 33 locations. A second run followed from December 5, 2024 to January 8, 2025 at 36 stores, and the third ran from October 9 to November 11, 2025 at 38 stores. The 2025 edition featured eight talents including Tsukino Mito, Higuchi Kaede and Kuzuha, with five rotating baths of four to five days each. The 2026 edition is therefore the series’ largest by store count and keeps the same structure: a general NIJISANJI bath first, then four talent-themed baths. The “totonou” in the title is the Japanese sauna-and-bath word for the relaxed, refreshed state after a good soak, which is the pun the whole campaign is built on.

What overseas fans should know

The announcement is aimed at visitors to the physical bathhouses, and neither the press release nor the campaign page mentions shipping abroad or foreign-language support. The online shop is the only route for fans outside Japan, and whether it ships internationally is not stated in the sources we read. If you plan to travel, remember that these are public baths and day-spa facilities with their own admission rules, so check each branch’s page for opening hours and closing days. For general advice on buying official goods from outside Japan, see our guide to buying official VTuber merchandise from Japan, and for the group itself see our NIJISANJI agency page.

What we don’t know yet

• Whether the online store ships outside Japan, and at what cost.
• The exact Plus Set pricing details beyond the one-line listing, and whether stock will run out early at popular branches.
• The full list of the 39 locations; the press release points to the campaign site and individual store pages for that.
• Whether any goods will be restocked after the campaign closes.

The organizers note that content may change without notice and that the campaign could be altered or cancelled depending on circumstances.
