Monthly Report of Sauna Facility Rankings
We present the February rankings of sauna facilities based on the "T-Flow Score" using measurement data from the sauna device.
Factors Behind Monthly Ranking Fluctuations
Monthly rankings of sauna facilities fluctuate due to various factors. Seasonal and weather changes alter the number of sauna users and comfort levels, which are then reflected in the rankings.
In addition, improvements to the Facility itself and event hosting also affect the rankings. As a result, the rankings are updated monthly, allowing all Sanokuni users to always obtain the latest information.

Average T-Flow Score Growth Rate: Compared to the previous month, it shows the rate of change in the average T-Flow Score at each facility. For example, +25.2% means that the average T-Flow Score increased by 25.2% compared to the previous month.
This concludes the monthly report for February.
