Singer-songwriter-actor Koike Teppei (22) made a surprise appearance at Odaiba on 18th August 2008 to promote his upcoming movie, Homeless Secondary School Student [ホームレス中学生] which opens on 25th October. The official website for this movie is here.In case you were wondering, those 4 girls around him are NOT fans (like I thought they were oops :p) but apparently comprise a 4-member Korean pop-girl group called Chun Sang Ji Hee - but are known in Japan as Tenjochiki. Their wiki article is here.
Yes, they are another SM Entertainment product sent to invade the Japanese market, and their reason for being here with Koike-san is that the theme song of his movie is sung by them. It is called [Here] and will be on sale starting from 22nd October.Koike commented n his four flanking compatriots, saying that "Their Japanese is really good. Also, they are bright and cheery and full of energy." before breaking into a shy laughter. In response, the 4 ding-dongs went, "Kakkoii!!!!" [Cool!] which made him even more embarrassed.
