You know what I'm talking about. Monsters based off Japanese folklore, martial arts like Judo or Karate, ninjas and samurai fighting to the death, Katanas = "Glorious Nippon Steel Folded Over 1000 Times", the annie mayz (anime) and the otaku that obsess over them, J-pop being worshipped, etc!
This isn't a list for ANYTHING AND EVERYTHING JAPANESE, but media with an emphasis on Japanese culture. Japanese people enjoying Japanese things like anime and ramen don't qualify unless there's an emphasis on educating viewers on anime/ramen facts. Sometimes I'll throw in applicable "weeaboo" (Japan fanatic of non-Japanese descent) characters in here just because I can, baka-tachi! WIP desu yo.
