KASOKU Co., Ltd. (Shinjuku-ku, Tokyo, CEO: Keisuke Arai, hereinafter "KASOKU") will participate as a hotel operator in the 3rd development fund for the new hotel brand "Sumu powered by Airbnb Partners (hereinafter 'Sumu')," which was born from Airbnb Partners (*1). This fund is executed through a real estate non-recourse loan (*2) provided by The Gunma Bank, Ltd. (President: Akihiko Fukai) and The Musashino Bank, Ltd. (President: Kazumasa Nagahori), with Sanko Asset Management Co., Ltd. (Chuo-ku, Tokyo, CEO: Shigeo Takei) entrusted with the asset management operations. This is the third fund formation, following ones up to November 2025 (*3).
[Background of this Project]
This project targets the hotel brand "Sumu powered by Airbnb Partners," created in collaboration with "Airbnb Partners," a unique Japanese business community launched by Airbnb Japan, the Japanese subsidiary of one of the world's largest accommodation booking platforms, aiming to grow the home-sharing market.
For Sumu, KASOKU, which also participates in Airbnb Partners, serves as the hotel operator. Culture Convenience Club Co., Ltd. (Yokohama, Kanagawa, Representative Director, President & CEO: Takanori Takahashi) handles content planning, and ADDReC Co., Ltd. (Shinjuku-ku, Tokyo, CEO: Taiga Fukushima) oversees design supervision.
[Value Provided by Sumu]
As inbound demand expands in Japan and lengths of stay increase, the need for "group stays" and the experience of "traveling like a local" in urban areas is growing. Born against this backdrop, Sumu adopts the brand concept: "There are stories you cannot encounter just through sightseeing."
"Hotel Sumu Akihabara North powered by Airbnb Partners (tentative)," currently under development, is scheduled to open in the Akihabara area, a town symbolizing Japanese pop culture including anime, games, and hobbies. Through spaces where guests can experience the extraordinary as an extension of everyday life, we will provide travelers with a community-rooted stay experience, rather than just a sightseeing base.
KASOKU will participate in facility operations as a hotel operator for this project, leveraging the hotel management expertise and implementation capabilities cultivated nationwide. By operating Sumu, we will address diversifying accommodation needs and the expanding inbound market, creating new travel options and community-rooted stay value. Furthermore, we will contribute to forming sustainable tourism infrastructure that coexists with local communities.
