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.
It was pretty good. I think I even broke a sweat.
It was very warm
I've used a similar product from another manufacturer, but it didn't seem to have any particular effect.
It was slightly thick, and I could feel the bath salts soaking into my skin even after I got out of the bath.
I really felt the heat retention effect! I felt like I was warmed to the core, and it was great to be able to go to bed in that state. When I use this bath additive on legs that are completely exhausted after a day of standing at work, I feel so much better when I get out of the bath!! I feel so light!! My legs reach their limit every day, so I want to use this every day to relieve them. The water becomes a little cloudy and soft. There is no scent. It dissolves a little slowly.
