Onsha, short for "Hot Spring Shower," is a product of research into ways to enjoy hot springs in the comfort of your own home.

The company developed a hot spring filter that freeze-dries natural sulfur hot spring water and inserts it into a shower filter.

When water and the hot spring filter meet, hot spring water flows out through the shower head.
