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

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.
