If you want to invite friends to travel to Japan, give me a SLR, Nikon and Canon. I don't know what is the situation in Japan.

1. Very convenient. Too many. Because he can't read Japanese characters, it's hard to find. I suggest "ビックカメラ" and so on. There will be one in front of stations in major cities in Japan, as well as duty-free shops in airports, but the models are not complete.

2. Generally, it's not much cheaper, just a few hundred RMB, and so are duty-free shops. Just take 1, and it's no problem to take two home. There is no need to pay taxes. I haven't tried to pay much with 10. . Ha ha laugh

3. I really don't know if I wear too much. I can't teach you to foul. At least 1, two is basically no problem.
