Many Japanese typefaces have areas in which the stroke width reduces to literally nothing in certain areas of certain characters. I don’t have an example handy right this instant, but I can probably come up with some if no one knows what I’m talking about.

Just out of curiosity, can someone explain why this is?

I'm looking for a font that will be able to translate some text my sensei sent me. I'm trying to design a card for him but for the life of me can not find a decent Japanese font for it (with Kanji, found a few kana ones). I think I might need unicode ?

looks awesome. but doesn't seem to work on my computer. I've installed for 20 and none seem to translate well, which makes me think I need unicode version?

I need to use this text:
山下武道こくさいきょかい

and help/direction would be amazing.
