Processing time and shipping estimates are different.
The entire amount of shipping fees are paid to the Japan Post. Once your item ships, it will usually arrive within the estimated shipping window (although delays are always possible and do not entitle a refund per JP Post). We do not include processing time in our shipping estimate. Our website states the processing time needed on our page. Order processing time is also stated in the order confirmation email. We apologize for any delays in order processing, however, it is not related to the shipping method you have chosen.
