On April 24, 2019 at 18:00, the Kamen Rider Picture Book website was unvieled. It’s a free database of Kamen Rider content available for fans worldwide, but content is Japanese language-only.
In the Kamen Rider Picture Book, you can see more than 150 Kamen Riders that appeared in Heisei Rider works. There is not only information about the monsters, transformation items, and characters but also a glossary with information about the Riders’ world.
Currently, only Kamen Rider Build is available, but more Riders will be released over time.
Similar to a Kamen Rider, the Picture Book will continue to evolve over time.
