It was bound to happen. Publisher Shogakukan in Japan has just issued the second of two manga Twitter comic books, explaining the benefits of social media. Drawn by cartoonist Yoko Gendai, the first Twitter manga called “Mitaka no Chushin de Nau wo Tsubuyaku” – or “I Tweeted Now at Mitaka” – depicts in manga cartoons the artist’s experience in registering with Twitter and mastering Twitter protocol. The second manga Twitter book, released September 25, called “Koma de Tanoshimu Tonari no Twitter” – or “Twitter – Joy of Twitter in 4-Frame Cartoon” – is drawn by Ajiko Kojima and relates amusing incidents that Twitter users face regularly. These two manga Twitter books follow on the heels of a Twitter novel called “Twitter Shousetsu – 140 ji no Monogatan” – or “Twitter Novels – 140 Letters Stories,” published by Discover Twenty-One. It features very very short 140 letter stories by ten established Japanese authors. One reviewer pointed out, however, that Japanese characters can convey roughly double the information possible in equivalent 140 English letters, so maybe that isn’t as impressive as composing a Twitter novel in English. Then again, the Japanese invented the 17-syllable haiku and the 35-syllable tanka poetic forms, so literary brevity is an inherent part of the culture.
