Popular Azur Lane x Sento Collaboration Returns with First-Ever Kyushu Location
Yostar Corporation announced that the highly acclaimed "Azur Lane x Sento Collaboration," an event tied to the smartphone game Azur Lane, will launch its fourth installment starting mid-November 2025 at three bathhouses across Japan.
Expanding to Three Locations Including First-Time Kyushu Venue
The "Azur Lane x Sento Collaboration" is a "healing event" that first launched in 2022, allowing fans to enjoy original illustrations of Azur Lane characters in yukata and other attire through various displays, decorations, merchandise sales, and stamp rallies, all while relaxing in collaboration-themed bathhouses.
For this fourth annual collaboration, the event returns to Tokyo's "Oshiage Onsen Daikoku-yu" and Osaka's "Tatsumi Onsen," both of which participated in the previous collaboration. Additionally, the event debuts in Kyushu for the first time at Oita's "Beppu Kannawa Onsen Yamanami no Yu," making this the largest-scale collaboration to date with three locations nationwide starting November 15, 2025 (Saturday).
Each venue will feature special initiatives that take advantage of their unique characteristics. Osaka's "Tatsumi Onsen" will offer a collaboration-themed private sauna called "Okomori Sauna" and special collaboration baths. Oita's "Beppu Kannawa Onsen Yamanami no Yu" will feature specially decorated "Private Rooms with Sauna and Bath." Tokyo's "Oshiage Onsen Daikoku-yu" will showcase the traditional collaboration sento mural alongside a scheduled talk show with Dai Miwaki, Yostar's PR and planning representative for Azur Lane. Be sure to visit each of these collaboration venues!

New Merchandise Featuring Characters in Yukata Now Available
New merchandise will be available featuring full-body illustrations of six characters appearing in the original key visual for this "Azur Lane x Sento Collaboration": De Zeven Provinciën, Lyon, Shimanto, Alsace, Essex, and Jade. The lineup includes acrylic stands that beautifully showcase these full-body character illustrations.
Additionally, venue-specific diorama acrylic stands feature a total of 10 deformed characters gathering at the bathhouse, including Vampire, Kinu, Le Hardi, and Voroshilov in addition to the six key visual characters. Be sure to check them out.
Furthermore, bust-up illustrations of Bai Long, Taihou, Unzen, and Kearsarge, which decorated the bathhouse interiors during the second and third collaborations, will finally be available as merchandise. The lineup also includes bathhouse staples such as coil key holders, towels with bottles convenient for frequent bathhouse visits, and mesh totes.
The collaboration will also sell the now-standard "Sento (Romance) Set" - a bath ticket that comes with a hand towel featuring the original illustration designed in a monochrome style - at all venues. Other venue-exclusive collaborations are also planned, including stamp rallies, collaboration drinks, desserts, and craft beers. Be sure to participate in these as well!
