Colette caught wind of the Ningyo-do Bunko, a library collection of drawings that depict designs and diagrams of toys and dolls from the late 19th century and early 20th century. There are over 100 albums contained within the database, and all of them provide you with a bit of an insight into an older toy culture in Japan.
Traditional Japanese culture is alive and well in all these toys, and as Colette points out, they'd likely scare Western children if you handed them something with a giant red face on it. All the pictures there are really worth checking out if you've got any inkling into toys or dolls. But then you'd probably be reading Tomopop already anyways.
