Would having your belly button pierced be weird in Japan?

I'm 17 years old and I live in Canada. I'm thinking about moving to Japan in a couple years. I have my belly button pierced and i love it and I'm just wondering if people would think it's such a strange bizzare thing over there or not. Maybe people would think im weird or rebellious? I also have 3 piercings in each ear, 2 at the bottom and 1 at the top of each(1 at the top is a small silver hoop and the other at the top is a flower shaped diamond) . What would be thought of that? They all look really cute to me! Thanks in advance!
