"The Japanese Tradition" was a series of nine short, parody "How To" videos that gently mocked the formality of Japanese culture, from comedy duo Rahmens (ラーメンズ) and Japan Culture Lab. They're available on DVD, but nearly all of them can be seen on YouTube, including Sushi and Ocha (tea). [more inside]
Comedy duo, Ramenz (ラーメンズ), aka Kobayashi Kentaro and Katagiri Jin, also known as the Japanese versions of Mac and PC, have recently done a number of shorts collectively called "The Japanese Tradition." Apparently, these tongue-in-cheek pseudo-instructional vids about famous aspects of Japanese culture (Tea, Chopsticks, Sushi, Origami, Apology, Onigiri, and Relationships) have been fooling a lot of non-natives into thinking they are actual guides. (YouTube, each approx 4-6 min).
Japanese Spider-Man seen here before, but this time he seems to be protected by a bandito type sporting a machine-gun guitar (but sadly, not one of these).
