When releasing a single in Japan, there’s normal edition and limited edition. There are several versions available. Depending on the version, prices range about 1000 yen to 2000 yen. Because of different version and prices, estimated price would be about 1,500 yen per copy. With that price in mind and thus calculation for their income: SNSD’s Genie and Gee sold for 217 million yen (about 3 billion won) and 105 million yen (about 1.5 billion won) respectively while Kara’s Mister and Best album sold for 150 million yen (about 2.1 billion won) and 225 million yen (about 3.1 billion won) respectively which in total so far is about 9.7 billion won of income.
SNSD and KARA will promote in both Korea and Japan at the same time. SNSD will promote ‘Hoot’ in Korea and ‘Gee’ in Japan. While Kara will promote new song in both Japan and Korea in November. Both groups are expected to have busy schedules.
