Mr. Torhihada and the Diamantes
There are so many Japanese performance artists that I know only a small minority of them. The Diamantes are a Japanese band. Mr. Torihada on the left, goes around with right wing slogans written on his suit, performing nonsensical dances in public places. I think that the idea is that his act is a parody or right wingers but in any event he is an individual of the Japanese type, full of passion and visual expression, with nothing to say.
You can see him performing here. He seems to be giving a run-down of his daily routine in the manner of a political speech. His use of Japanese on his suit is interesting. The Japanese are happy to put English on their clothes, but as soon as they put Japanese on their clothes it gives the impression of proclaiming the words very strongly. This relates to Nakashima's assertion that language is and should be public (announcements, signs) but not private in Japan, since private speech (such as in classrooms, or on trains) is considered to be very loud. Likewise Mr. Torihada's slogans look very loud, though if they were written in English then they'd hardly be noticed.
