As a rule of thumb, if a game was made in Japan, it's going to be at least a little weird. But some games go above and beyond when it comes to that legendary J-Factor, and as such I've compiled what I believe to be the 10 most insanely Japanese titles ever slapped on a videogame.

10. "Fly Mr. Science: Great Expedition of the Earth! Challenge the Mysterious and Strange Creatures"

Let's start this list off right. Fly Mr. Science is a game that takes the bridge of cultural understanding we share with Japan and carpet bombs it out of existence. The strangest thing about this game, however, isn't that the main character is an unlicensed scientist without skin, but the fact that it's based on an educational Japanese children's television show. This game is their SchoolHouse Rock, and that explains so much about so many things.
