Sumu Hotel Launches Official Site for a New Travel Experience

Exploring a New Era of Travel: Launch of Sumu Hotel's Official Site

On October 23, 2025, Kasoku Inc., located in Shinjuku, Tokyo, officially launched the brand site for Sumu, an apartment hotel brand powered by Airbnb Partners. This initiative represents a significant step towards redefining travel by creating new value in the realms of culture and business. Sumu’s mission is to encourage a transformative travel experience that goes beyond mere accommodation, fostering connections with local culture and communities.

The official Sumu website, accessible at https://sumu-hotel.com, serves as an information platform for guests, businesses, local governments, creators, and communities to learn about Sumu's goals and collaborative efforts. The website features various content, including the Sumu Lab, where guests can gain insights into case studies of co-creation and reports on unique accommodation experiences.

Background and Purpose of the Site Launch

In recent years, the way people travel and stay has evolved dramatically. Tourists are now looking for experiences that allow them to engage with local culture and forge meaningful connections. Simultaneously, local communities face challenges in utilizing tourism resources for sustainable revitalization, thus necessitating innovative forms of value creation.

Consequently, Sumu was born as “a hotel experimenting with new travel forms,” aiming to provide apartment-style accommodation that transcends traditional stays. The brand serves as an open innovation platform for co-creating new cultural and business values in partnership with various stakeholders.

Information Hub for Collaboration

The newly launched official site acts as a core platform for disseminating Sumu's initiatives and fostering connections with co-creation partners. It clearly communicates Sumu’s vision and business strategy, making it beneficial not only for prospective guests but also for community revitalization enthusiasts and those interested in collaborative ventures.

Key Features of the Site

1. Immersive Brand Story: The homepage reflects Sumu’s multifaceted values through visual storytelling, encapsulating the essence of living, creating, and enjoying.

2. Clear Presentation of Business Dynamics: With a dual identity as both an accommodation facility and a co-creation platform, Sumu’s business model is visually represented through diagrams and infographics, allowing visitors to grasp the complexities of its operational model.

3. Continuously Evolving Value through Sumu Lab: This section serves as a media outlet depicting Sumu’s vision for future travel and lifestyle, sharing insights through various content formats.

Unique Design Contributions

The website’s development involved a collaboration between ADDReC, which handled the brand strategy and business design, and creative studio Whatever Co., which focused on visual design and UX. This collaboration has resulted in a seamless blend of strategy and creativity, offering a polished user experience that draws visitors into Sumu's world.

Sumu: A Commitment to Community and Culture

At the heart of Sumu is the belief in creating a space that deeply engages with local cultures and communities, enabling travelers to craft their unique journeys. The brand seeks to collaborate with businesses, local governments, and creators to uncover new possibilities and elevate cultural and business intersections.

In February 2026, Sumu will launch its prototype model in Tobu Ueno, setting the stage for the future of travel accommodation in Japan.
