Miraichan (未来ちゃん) is a book that consists almost entirely of photos of this extremely, extremely cute girl. It’s starting to make a run up the bestseller lists like Ume Kayo did a number of years ago. Incidentally Ume and Kawashima, along with Patrick Tsai and others, are all part of Hajimeten, a new art group.
I’ve seen it written a couple of places that Kawashima is a woman, or even Mirai-chan’s mother, but he’s a guy.
If you have even the slightest interest in Japanese photography, STREET LEVEL JAPAN is a tumblr (and blog) to follow.
You will consistently find good things there as Dan Abbe has all kinds of insight, intelligence, and connections regarding Japanese photo scene.
