Why is the Tiger/German Suplex wrestling move so popular among anime culture? I see a lot of fan art that depict this move (even though nothing of the sort happens from the show/series where the characters came from) and even in Nichijou we have the school principal giving a deer a tiger suplex:

Episode 87 of Gintama is: "Perform a German Suplex On a Woman Who Asks If She or the Job Is More Important"

From Lagrange, the mechas do one:


And all the endless fanart:









Why is this so popular? Is this because wrestling is popular in Japan? But why this specific move?
Yes, it's very likely because of the popularity of puroresu (wrestling) in Japan. Antonio Inoki is credited with making wrestling popular in the country and he himself was impressed with and inspired by the amateur wrestling style of Karl Gotch (nicknamed Kami-sama) who had become famous in Japan. The German suplex was Gotch's signature finishing move.



There's a compilation of Gotch's moves on YouTube.
