Yes, we only ask that you be patient and we will work with you. Japan Post has a very good reputation for providing excellent service, and we support them 100%.
If you selected a "registered" method of shipping (with a tracking number), we can issue a refund after sufficient delivery time has passed.
If you chose "International Parcel - Surface", then please be patient. These days with transportation shortages, delivery delays, and the current world situation, "surface" parcels can take the full three months and maybe even a week or two more. If we determine that your parcel is indeed "lost", we will issue a full refund. If any items are "expired" when you receive your parcel, contact us and we will issue full refunds for the expired items. (This is usually not a problem as we ship only the most recent items available when we pack your order. However, since there are a few products which simply don't have a long shelf life even at the time they are manufactured, it may happen on very rare occcasions).
