You should hear back soon
Hi HIDETAKA UCHINO,
We just let the seller know that you want to cancel your order. We'll email you as soon as we hear back.
You'll likely hear back sooner, but the seller has 3 days to reply. If the seller already shipped it, they won't be able to cancel your order.
If the seller approves your request, they should send a refund for the purchase price and original shipping back to your original payment method.
We'll be in touch soon.
