We apologize for the inconvenience, but we will begin shipping from May 6 (Thu. ) after the Golden Week holiday.

During Golden Week and the period around Golden Week, delivery may be delayed due to the concentration of orders and traffic congestion.
Please note that we may not be able to meet your request even if you contact us or the delivery company to inquire about the delivery status and your preferred date and time.

The delivery will be made sequentially, but due to heavy shipping congestion, it may take longer than usual for delivery.

Please understand this in advance.
