A distinctive feature of Rental Space ripple is that it offers a variety of learning and recreational activities that make use of the space.
In addition to one-off events such as various classes, popular activities are held regularly as “clubs.”

Club activities include sutra copying, yoga, various classes, and bookkeeping, as well as activities across a range of genres, such as board game tournaments.
ripple Honzo Mugwort Steam Therapy, HAKKO STAND (Fermented Drinks), and Bath Additives

In addition to rental space, the facility offers ripple Honzo mugwort steam therapy and fermented drinks.

ripple Honzo mugwort steam therapy began in 2023, and since 2026 has used a custom herbal blend developed by Kato. Guests can receive care tailored to their health and needs.
HAKKO STAND makes and sells a fermented drink called kombucha. Kombucha is not tea made with kelp.
It is a drink made by slowly fermenting tea with acetic acid bacteria and yeast, and is attracting attention as part of a daily health routine.
In addition to kombucha, enzyme drinks and amazake are also available.

Herbal bath additives are also sold so that customers can continue caring for their bodies at home and enjoy them with their families.

ripple Farm
Activities extend beyond the facility as well.
A “ripple Farm” has been established in Soja City, where since 2025 the team has been working with friends to cultivate a field without pesticides or chemical fertilizers. They are preparing the farm so that herbs used in bath additives can also be harvested there in the future.

Underlying these wide-ranging initiatives is a consistent desire to “help visitors feel energized” and “give them time to heal themselves.”
