I've taken a look at this Keishirou & can see a replacement for order 173912975 has already been sent out to you. This was replaced on the 30th November. This should have arrived with you on the 18th December, however in case of any postal delays the latest your joggers should have been with you was the 11th January.
The delivery address these were sent to is - Dynamic CorporatinoHB308, 777-2 Shimotaga, Atami, 4130 102, Japan. Can you please check with anyone else at this address for your parcel, your neighbours, any safe places your parcel could have been left & with your local post office as they should be able to give you some more info on this. If you still have no luck, let me know & I'll look into this for you.
この荷物についてこの住所の人や近所の人に確認してもらえませんか。荷物が安全な場所に置かれているのかもしれませんし、最寄の郵便局で聞けば、この件に関してもっと情報が得られるはずです。それでも見つからなければ、お知らせください。こちらで調べてみます。
