Japan Couture Addicts is a blog dedicated to showing off projects made from Japanese craft books. The blog is in French so if you speak another language you will need to use Google Translate. I love the style of Japanese craft books and enjoy viewing the projects of the many different users.

There is also this excellent site: Crafting Japanese. It is no longer being updated (as of June 2010), but is an excellent resource of books and links to people who have made things from the books.
