Introducing FLEXKEY: A Subscription Service for Off-Peak Sauna Usage in Japan

FLEXKEY: Revolutionizing Sauna Experience in Japan

The world of wellness is rapidly evolving, and one of the most exciting new developments is the launch of FLEXKEY, a subscription service aimed at making sauna experiences more accessible to a wider audience. Developed by OPTIMIST, a Tokyo-based company led by CEO Shunsuke Matsuyama, FLEXKEY enables subscribers to enjoy sauna and bathing facilities during specific off-peak times for a fixed monthly fee. Recently, it garnered incredible attention on the crowdfunding platform Makuake, achieving an astonishing ¥10,945,000 in support from 492 backers, far exceeding its initial goals with a completion rate of 2,189%.

What is FLEXKEY?

FLEXKEY focuses on addressing the underutilization of sauna facilities during quieter hours, such as weekdays during the day or late at night. By allowing customers to access these less crowded times, FLEXKEY offers an affordable way for sauna enthusiasts to enjoy high-quality bathing experiences. For the facilities, this translates into optimized usage of their business hours and ultimately leads to a win-win situation for both users and providers.

The concept behind FLEXKEY is to integrate sauna experiences into the daily health routines of its users, moving beyond the notion of sauna as a luxury, special occasion activity. FLEXKEY aims to encourage the Japanese population to embrace regular bathing habits, contributing to the sustainable growth of the sauna and bathing industry as a whole.

Unprecedented Response and Future Plans

The launch of FLEXKEY received a remarkable reaction from the public, with interest surpassing OPTIMIST's expectations. As a measure to ensure stability and a successful rollout, the company decided to temporarily halt new member registration. The focus is now on preparing for a gradual launch aimed at the Makuake supporters, ensuring that all aspects of the operation, from system stability to frontline operations at partner facilities, are thoroughly evaluated. A broader public launch is anticipated to be ready by the early months of 2026.

Expanding Partner Facilities

During and after the Makuake project, numerous sauna and bathing facilities expressed interest in collaborating with FLEXKEY. In response to this positive feedback, OPTIMIST plans to accelerate the expansion of its partner facilities across all 47 prefectures in Japan. FLEXKEY offers a no-cost, profit-guarantee model that enables establishments to capitalize on their underutilized hours without altering their entire pricing structure or imposing significant operational burdens.

For facilities interested in joining, FLEXKEY is open to discussions on flexible partnership terms during this initial phase. The partnership goes beyond just a business model; it’s about creating a network that enriches the overall sauna culture in Japan and encourages more individuals to benefit from its health advantages.
