"Kanjani8's Nishikido Ryo (25) will appear in a Tv CM for Seven Up, which is a carbonated drink with no calories intended for working adults.
With the catchphrase "motivation for work!", the working adults will be able to enjoy it. The stimulus from the refreshing carbonic acid will be expressed through an air guitar. Nishikido looked embarrassed because it was his first time doing an 'air guitar' but because he can actually play the guitar, as the takes progressed he showed off his skills and a well done air guitar can be seen in the finished CM. It will start airing on the 3rd of August."
The translation sucks but I think you can get the general idea?
