Ideas for a Japan themed party?

Question:

I'm having a Japan themed party for my birthday (5th of december) because I love Harajuku, fairy kei, kawaii, anime...
I know a lot of people have Japan parties know, so I've searched on google, but mostly it comes up with oriental japanese decorations and fancy dress. I want my party to be more modern, with fun harajuku and fairy kei style ya knooww...

So if you have any anime,video game, harajuku, japanese style related ideas for decorations, costume activities.. help!

Thanks! x
