What it is
No synthetic surfactants are added, and the only cleansing ingredient is soap. It removes plaque, cleanses the mouth, and prevents cavities and bad breath. It also prevents tartar buildup and whitens teeth. It has a mild, bitter toothpaste taste, doesn't create too much foam, and isn't too harsh even when brushing slowly. It has a refreshing flavor that combines two types of mint: Japanese mint and spearmint.
Ingredients
Calcium carbonate, water, glycerin, potassium soap base, peppermint oil, spearmint oil, licorice root extract, tea leaf extract, xylitol, BG, tocopherol, sodium gluconate, xanthan gum
How to use
[Caution] If any rash or other abnormalities occur, discontinue use and consult a doctor. If the product gets into your eyes, rinse immediately with plenty of running water without rubbing. After use, be sure to close the lid and store. After opening, use as soon as possible.

Do you offer express shipping?
Yes. As of 22 July 2026, we offer International Express Mail through Japan Post. The cost is based on order weight and is calculated automatically at checkout.
Will I pay customs or import fees?
US orders: No. As of July 1, 2026, all US orders ship DDP (duties delivered prepaid), meaning we prepay all import duties on our end. Nothing is due at your door.
Orders outside the US: Possibly. Duties and import taxes are set by your local customs authority and are not collected at checkout, so any charges on delivery are your responsibility.
We're working on rolling out prepaid duties for more countries soon.
