Uebanet put together a collection of 12 Japanese inventions that "never quite took off". It's tough to pick a favorite from the list, but I do enjoy the Hair Blocker. While apparently designed to prevent females/hippies/80s rockers from getting hair in their noodles, it doubles as a intimidating lion mane or cheery sunshine hat.
Our other favorite?
The 360-degree camera. Why it requires a harmonica to operate the world will never know, but we strongly encourage hitting the link for 10 more gadgets that are also each considered our personal favorite.
