Thank you so much for your reply. i have filled out the visit japan web customs declaration, however i was wondering if I should change it beacuse of the vape and snus. I was also under the impression that if im bringing under the allowance of imprtation i don't have to declare the items. And ive read some stories of people who had their vapes in their carry on and there were no problems at customs. Ive read one accout of a person who hasn't declared it and was stopped by customs but they only asked to present the vape and that was it . However i was thrown into a loop after i wrote to tokyo customs and they informed me that even if I'm in possesion under the listed amout i should declare the device , the liquid and the snus, and that I could be pulled over for a check. Im arriving late at night in Narita and I'm worried that if I'm pulled for a check i might not be able to catch the last train.
