FYI, "sugoi" means "great!" and is used sort of like "awesome!" As in this sentence: Bibliofind has posted another awesome source for 19th and 20th century Japanese toy designs: the Ningyo-do Bunko Database. Ningyo is doll, so there will be lots of look-don't-touch designs and artifacts, but there are plenty of playable toys as well.
These watercolor sketches of various folk toy designs [kyoudo gangu, if you remember from last time] come from a 60-volume set. The simplicity of a paper lantern-like hanging octopus, and the wobbly walking motion of a dragon pull-toy barely scratch the surface.
