Kadokawa Culture Museum claims to have the world's largest collection of light novels.

On Thursday, the Kadokawa Culture Museum held a post-refurbishment opening ceremony. The "Manga/Light Novel Museum" is located on the first floor of the building. It currently houses around 35,000 books and bills itself as "the world's largest light novel library."

On August 1, the museum opened to the public for the first time. At the time of its opening, it housed 25,000 books, including nearly every Kadokawa light novel in existence, as well as a selection of comics and juvenile literature. Kadokawa has since expanded the collection with a further 10,000 books as part of its Light Novel Archive Project, with the help of 18 other publishing companies.

On the same floor, the establishment has also opened the "Da Vinci Store (Manga/Light Novel Library) Satellite Branch," which will sell light novel-related goods.

The museum is part of the Tokorozawa Sakura Town facility, which is part of the "Cool Japan Forest Vision" collaboration project between Kadokawa and Tokorozawa City. The goal is to attract foreign visitors to the often overlooked Saitama area. The facility also includes the interactive EJ Anime Hotel, which debuted in October.

The project is part of the Japanese Ministry of Foreign Affairs' "Cool Japan" initiative, and the name "Cool Japan Forest Vision" refers to the lush greenery of the area. The project, which was first announced in 2015 in anticipation of the Tokyo 2020 Olympics, is expected to cost 30 billion yen (US$238.8 million).

From July 17 to September 26, the Kadokawa Culture Museum will host a "Isekai Museum" exhibition featuring storyboards, key animation, and artwork from the anime series Re:Zero, Overlord, KONOSUBA, and The Saga of Tanya the Evil. The exhibition is also accessible online.
