So a while ago my girlfriend's friend bought me a T-shirt with 白樺派 emblazoned upon it. And every time I wear it (wherever I wear it) someone from Japan will come up to me to ask me about it. Which gets a bit embarrassing, because I don't know a huge amount about 白樺派.
Now I broadly know that 白樺派 was a literary movement, devoted to individualism. But I really don't know much more than that, and the internet really doesn't seem to want to help.
So does anybody know anything more about 白樺派, so I can amaze and impress anybody who asks me about my T-shirt (instead of embarrassing myself with my lack of knowledge)?
