You also ask when you will receive the second shipment from this same order. I have contacted the carrier, iParcel, who have advised that the latest status is that the shipment containing this parcel had landed in Japan and this parcel is about to go to Customs and then to the last mile carrier, Sagawa, under local tracking number WM00000000JP.
In plain terms, your order should be with you very shortly. Please accept my apologies for this delay and inconvenience.
わかりやすく言うと、お客様の荷物は間もなく届くはずです。今回の遅れ及びそれに伴ってご不便をおかけしましたことについてお詫び申し上げます。
