Launch of Curated 'Sabento Ramen' to Transform Onsen Facility Attraction｜First Collaboration: Ofuro no Ousama Machida × SUSURU TV. (Launch on June 26, Bath Day)

King's Exclusive Special Soy Sauce Ramen: Price TBA ¥980 (tax included)

MAFUMO, Inc. (Headquarters: Setagaya-ku, Tokyo; CEO: Masashi Kikuchi), operator of the head spa specialty store 'RESET LABORATORY (Riserabo)', announces the launch of planning, development, and production of 'collaboration ramen' and 'sabento ramen' curated by ramen YouTuber SUSURU for onsen facilities. As the first initiative, MAFUMO has developed the 'SUSURU-Curated Special Soy Sauce Ramen' (priced at ¥980 including tax) in collaboration with 'Ofuro no Ousama Machida' (Minami-ku, Sagamihara, Kanagawa Prefecture), a super sento facility, and SUSURU TV., a popular ramen YouTuber with over 1.7 million subscribers. Sales will begin at the facility's restaurant on Friday, June 26, 2026. Media inquiries and consultation requests from other onsen facilities are now being accepted.

Background: 'Sabento' as a New Key to Customer Attraction and Differentiation for Onsen Facilities

With the rising popularity of saunas and onsen bathing, interest in 'sabento' (sauna meals) enjoyed after bathing is rapidly increasing. However, differentiating in-house restaurant menus remains challenging. Onsen facilities are increasingly expressing the desire to 'attract customers and increase average spending with a trending ramen dish' and 'create a signature original dish for the facility'.

Having executed numerous collaborations with onsen facilities through 'RESET LABORATORY', MAFUMO, Inc. is launching a new service that combines the popularity of ramen YouTuber curation with product design tailored to facility operations: a curated ramen development and production service for onsen facilities. The first project realized is the collaboration between 'Ofuro no Ousama Machida' and 'SUSURU TV.'.

Service Overview: End-to-End Support from Product Development to PR

We provide comprehensive, end-to-end production for onsen facilities, sauna facilities, and restaurants, including:

- Recipe and Product Development: Flavor creation tailored to the facility's concept, including soy sauce, miso, salt, and inspired styles

- Productization and Supply Design: Optimization of serving formats to match store operations and ensure stable supply

- PR and SNS Amplification: Press release distribution and topic generation through the curator's SNS and YouTube channels

We welcome inquiries from onsen facilities and operators interested in introducing 'facility-original curated ramen' or using 'collaboration ramen' to boost customer attraction and average spending.
