Going to Japan is not to check whether what you are wearing is true or not, so no one will look at what brand of clothes you are wearing. As long as you leave the country legally and carry the goods in line with the regulations, no one will ask you. Of course, you don't have to cut off the trademark. It will be unsightly if you cut it off. I used to mention my fake crocodile crossing the border all the time. There is no problem. I also brought four cameras from the customs, and nothing happened, as long as you put the other three in the checked baggage.

but I started to reserve your fingerprints a while ago, the index finger's.
