Thank you very much for always using our website.
Points can now be used on both the official website and retail stores!
■ 5% points back on all products
If you register as a member on this site, you will receive 5 points for every 100 yen of the tax-excluded product price you purchase (5% return rate).
1 point can be used as 1 yen.
■After registering as a member, make sure you are logged in when shopping in order to earn points.
Please note that if you make a purchase while not logged in, you will not receive points.
*Shopping points will be awarded when the product is shipped, not when the purchase is completed.
