It's not just music that Japanese fans of Girls Generation can't get enough of. It's book releases from the popular idol group as well. Or, at least a book featuring many pictures of them.

The group's first Japanese photograph collection book titled "Holiday" was number one on the book sales ranking chart in the photograph category. In the overall book sales rankings, "Holiday" placed 18th. Various photos in the book show off the girls enjoying their time off.

17,000 copies were sold in just the first week after hitting the shelves on November 30th.
