Bath Additive "Jitaku Mushi"

Experience "mugwort steaming level" at home.

Shinsei Co., Ltd. (Headquarters: Japan) is pleased to announce that its authentic bath additive "Jitaku Mushi," developed by its mugwort steaming specialty store 【Yomogurumi】, has exceeded 1,000 cumulative sales as of May 1, 2026.

■ Even on days you can't go to the salon, get salon-quality care at home. Background to its launch.

"I want to properly take care of myself even on days I can't go to the salon."

"I want to take my family to mugwort steaming, but it's hard to find a day that works."
It was from such customer feedback that the authentic bath additive "Jitaku Mushi" was born.

Based on our track record as a mugwort steaming specialty store, having addressed the physical constitution care of over a thousand people, we have incorporated our salon's "results-oriented" philosophy directly into this authentic bath additive for home use.

Users have provided feedback such as:

・"I stay warm even after getting out of the bath!"

・"I was surprised by how clear my skin was the next day."
・"I feel warmed from the core."
・"I slept soundly and well!!"

・"The quality of my awakening the next morning is different!"

We designed it to reproduce that experience at home.

■ A quasi-drug with an "authentic design" created with the direct knowledge of a pharmaceutical doctor specializing in Chinese medicine.

"Jitaku Mushi" is an authentic quasi-drug bath additive created with the direct knowledge of a pharmaceutical doctor specializing in Chinese medicine.

・Blended with 8 types of high-quality crude drugs.
