Those coming to Japan from overseas should be careful.

Even if you paid a lot of money to buy something in your own country and bring a souvenir to your family or friends living in Japan, there are some items that you are not allowed to bring into the country. This is determined by Japanese law.

Crying or yelling at the airport quarantine officer that you want to bring something in will not change the law. If you are carrying prohibited items, they will be confiscated at the airport.

 To avoid time spent at the airport being questioned and stopped to submit to baggage inspection, please do your research in advance and enter the country in compliance with the law. Enjoy your stay in Japan and do not waste the limited time you have left.
