What is ZenPlus?
ZenPlus is an online shopping platform connecting Japan with the rest of the world. We're part of the ZenGroup, Inc. umbrella in Osaka, Japan.

Are items authentic?
Our sellers' agreement fully compels all stores to list only authentic items. We help you buy exclusive and authentic items from Japan, online!

Do you ship to my country?
We ship to all countries where Japan Post air freight services and international couriers currently operate. We don't use surface mail.

How long does shipping take?
Domestic shipments generally reach our warehouse in a few days, but may in certain specific cases take a week or more. International shipments can take anywhere from several days to several weeks to reach you after leaving our warehouse, depending on if you choose Standard or Express shipping.
Please contact our support team from the Questions section on your account page if you have any questions about the timing of your parcel.

How much is shipping?
Shipping costs depend on the size, weight, and destination of your parcel. We provide shipping costs for your order at checkout.

Will I be charged a customs (import) fee?
It depends on your country and its customs regulations. Our service does not cover duties and import taxes — in general, if the customs office in your country applies charges to your package, you are required to pay them.
