First and foremost! Oshikatsu is essentially just super-dedicated fan culture. You can
read more about it on wikipedia. The idea is to show a lot of support for your oshi, literally meaning favorite or designated person of support. I've always been very obsessive about my interests, so the term is new to me but the need to show extreme dedication is certainly not!
Oshikatsu typically involves spending a lot of money, which I can't do. So I thought it'd be fun to share some of my DIYs! Navigation on the left sidebar.
