FLEXKEY Expands Subscription Sauna and Bath Services with 14 Facilities in Tokyo

FLEXKEY Expands Subscription Service for Saunas and Baths in Tokyo



FLEXKEY, operated by OPTIMIST, is a subscription service that allows users to enjoy various sauna and bath facilities throughout Tokyo. As of February, the number of partnered facilities has grown to a total of 14, following the recent addition of seven new locations in just two months. This noteworthy expansion signifies FLEXKEY's commitment to providing diverse bathing experiences, enabling users to utilize facilities like traditional hot springs and super sento, all under a convenient monthly subscription model.

Recent Developments



Since its inception, FLEXKEY has been focused primarily on sauna facilities but has now broadened its scope to include a myriad of bathing establishments. The addition of new partner facilities such as Matsumoto-yu Myouhou-yu, Egota-yu Sugamo-yu, Saunarrium Koenji Manten no Yu, and Private & Shared Sauna KUUMA creates a rich array of options tailored to different lifestyles and preferences.

As FLEXKEY continues to expand, it aims to enhance the overall user experience by incorporating more facilities that cater to a variety of needs.

Pricing Adjustments and Future Outlook



With the increase in partnered facilities, FLEXKEY is implementing a new pricing structure aimed at ensuring sustainability and expanding the value of its offerings. Starting from the upcoming year, the monthly fee will be revised to ¥5,900 (tax inclusive ¥6,490). This change will further facilitate regular users in accessing a broader range of facilities at an economical price point. Currently, FLEXKEY is in a phased rollout phase for Makuake backers, with public access anticipated to begin in the next few months. An official announcement regarding the resumption of member recruitment is forthcoming, including potential limits on enrollment to streamline service delivery.

Addressing Industry Challenges



FLEXKEY recognizes the challenges faced by sauna and bathing facilities, making it a valuable partner in the industry. Many establishments struggle with attracting customers during off-peak hours, leading to operational inefficiencies. FLEXKEY offers a tailored solution, allowing facilities to allocate their resources better and optimize income without incurring additional operational costs. The arrangement ensures that participating facilities receive a fixed monthly contract fee, stabilizing income while also increasing foot traffic during typically slow hours.

Joining the FLEXKEY Network



Facilities interested in joining the FLEXKEY network can request information through the official form. Offers of case studies from current partners, insights into potential revenue growth, and personalized simulations are available to prospective partners. This unique opportunity enables establishments to assess the potential benefits of collating with FLEXKEY while demonstrating a commitment to elevating the sauna and bathing experience for a broader audience.

Conclusion: A Vision for the Future



FLEXKEY strives to transform sauna usage from a luxury experience to a routine wellness activity. With ongoing efforts to expand their portfolio, improve app functionality, and enhance the customer experience, FLEXKEY is poised to redefine what it means to enjoy saunas and baths in Tokyo. The future of wellness is bright with FLEXKEY!
