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.
I was buying some for travel and was attracted by the fact that it had been on the best-of list in the past. I wasn't particularly impressed, but I'm not dissatisfied either, so I'll buy it again if I have the opportunity.
I used the yellow one but this one is good too!
It leaves your skin feeling smooth. It has a nice, elegant scent that doesn't feel cheap. I don't feel like I have to have this, but I don't dislike it, so I might buy it again.
I bought it as a trial ^ ^ The scent is nice and it's well-balanced! I'd like to buy it again!
The shampoo lathered well and had a nice scent. I prefer the hair treatment to be a little more moisturizing, but it didn't leave my hair feeling rough after washing.
