Okay, so I have found some more blog-worthy [Japanese] artists! Super!
First there is Atsu Mori. I like her stuff a lot ... it's kind of folky, but also very modern. And I think she works with quite a range of materials ... like, she does actual paintings, but she also does a lot of installations and sculpture-type stuff. I think. I need to get better at reading Japanese, I guess. Since I'll be there for a bloody year.
Next, we have Ai Kijima, another female artist. Now Ai, I believe, is actually trained as a textile artist. So a lot of her work has a very organic feel. Also, she utilizes collages a whole lot, which I think is really cool as well.
