About this app

Visualize your "totonoi" experience with data by linking with Sawatch (SHOWDOWN 1).
This app is for sauna lovers, bringing the science of sauna to the forefront.

Introducing the features of "Sa no Kuni," the app that brings the science of sauna to the forefront.

■ Record your experience and discover your own "totonoi" experience
By linking with Sawatch, your app will automatically record not only the elapsed time spent in the sauna, cold bath, and rest periods, but even your heart rate. This allows you to visualize how safely your sauna experience contributed to your day's sauna experience! Furthermore, by reviewing your heart rate and autonomic nervous system performance during each session, you can understand how your body is responding and use this information to explore your own "totonoi" experience! With a premium plan, you can also view detailed data for each session, comparing changes between sessions to more deeply explore your ideal sauna experience!

■ Check your post-sauna sleep quality with numerical values
You can link with Sawatch (SHOWDOWN 1) to automatically sync your sleep data. You can also record any factors that may be affecting your sleep, making it easier to reflect on what's affecting your sleep. If you have sauna experience records, they're linked to your sleep data and saved, allowing you to analyze the sauna's effect on your sleep!

■ The more you visit, the more "Sauna Seals" you'll earn.
The more sauna experiences you record, the more "Sauna Seals" you'll earn based on various criteria. For example, the number of times you visit various saunas, the number of times you've returned to the same sauna, the number of times you've created records, and even if you record a sauna on an event day like March 7th (Sauna Day). Some of the conditions are a little challenging, so please give them a try. If you manage to get one, you'll be able to brag to your sauna friends!

■ Search for over 5,000 sauna facilities nationwide. When you're on a business trip or somewhere unfamiliar with the area, it can be hard to know which sauna to go to, right? "Sauna Country" uses GPS information to find nearby sauna facilities. You can find everything from popular facilities to hidden gems known only to those in the know!

■ All basic functions are free!
We want as many people as possible to enjoy saunas. We also want sauna facilities, which can be considered a vital part of health infrastructure, to continue for a long time to come. With that in mind, this app is free to use. The premium plan offers even more content to enhance your sauna experience, including access to more detailed data and exclusive sauna seals.
