Nijiiro no Sakana, or The Rainbow Fish, is a children's book by the author and illustrator Marcus Pfister which was released back in 1992. It became something of a cult-classic, and has been translated into 57 different languages and read by over 30 million people.
A special event at the Kobe Fashion Museum looks into around 180 works from Pfister, including original illustrations from the iconic book. There will also be a section where you can head into the picture book world courtesy of computer-generated images.
Adult admission to the event is priced at 1000 yen.
