― Integrating Reservations, Payments, and HUUM Heater Remote Control into a Single Platform ―
SAUNATURE LLC (Headquarters: Karuizawa-machi, Kitasaku-gun, Nagano Prefecture; Representative: Aurimas Alko) today launches the official version of 'SAUNATURE,' a reservation and business management system exclusively for sauna facilities. It is the industry's only SaaS for sauna facilities that integrates reservations, payments, and even remote control of Estonian-made HUUM sauna heaters into a single platform.
Since the beta launch in October 2025, we have made improvements through operation with partner facilities, and the official version adds new features, including a plan page creation function.
## Hardware and Software Integration - SAUNATURE's Unique Position
While there are multiple reservation systems for sauna facilities, SAUNATURE is the only one that can operate a sauna stove from software.
Because the company is built on a hardware sales business of sauna stoves and cabins, it has achieved native integration with HUUM heaters.
While other companies do not specialize in saunas due to market size considerations, SAUNATURE has established a unique position by providing everything from hardware to software.
- Remotely control the heater's on/off and temperature.
- Manage multiple sauna rooms with a single smartphone (the standard HUUM app supports only one room per device).
- Cold plunges can also be operated remotely.
- Automated operation linked to the reservation schedule reduces standby power and streamlines preparation and closing tasks.
## Designed Specifically for Saunas, by Those Who Know the Field
- Automatic linking of private and public inventory: When a private booking is made, the public slots for that time are automatically closed. This prevents double bookings and frees you from manual adjustments.
- Payment processing fee from 4.4%: Industry's lowest level, including credit card fees. The more sales increase, the greater the cost benefit.
- A virtuous cycle of fan-building and monetization: Sales and management of annual subscription memberships, online advance payments, LINE integration.
