I actually see women wearing hijab almost everyday in my neighborhood. I happen to live in a very cosmopolitan neighborhood north of Shinjuku, so please don't think this is the norm for all of Japan. There are countless Japanese-language schools and at least 3 or 4 Halal grocery stores near me. Many embassy-related Islam women come to this area to buy Halal food, too. (They can park anywhere and stilll won't get tickets!)

If you go to smaller cities, you may get curious stares. But that's what I get when I go outside of Japan as well. So that's just to be expected. You should be fine living in Japan.
