Due to Japanese public holidays, our office will be closed and all operations will be paused during 12/28/2018 - 1/6/2018. All orders placed within those dates will be shipped as early as possible starting from 1/7/2019.
Secondly, during the holiday season, the amount of mail going through Japan Post is unusually high, which may cause some shipping delays. You can find information about this on Japan Post’s website here: https://www.post.japanpost.jp/int/information/2018/1031_01_en.html
Don't worry if your box hasn't arrived within the expected arrival date (3-4 weeks after the shipment date), we suggest you wait 2 more weeks before contacting our customer support.
