Rainbow's second single album in Japan ranked top 10 on the day of release.

On December 7th, Rainbow released the second single album 'Mach' in Japan, ranked 8th on Orikon daily chart.

It was remarkable achievement considering the competition with Japanese top stars, such as AKB48, Amuro Namie, and Korea's Super Junior.

Rainbow ranked on top 10 two times in a row since the first single 'A' ranked 3rd on the day of release in September.

The team is scheduled to be on the first solo concert in Japan, including Osaka, Tokyo, and Nagoya.
