So here's Mariya Nishiuchi's 5th Single: Chu Chu/Hello and "Chu Chu" was used in a commercial for ABC-Mart's NUOVO FIT PUMPS FLEX shoes!

I find this cute and really refreshing.  This single is really different from her past releases which has a strong and a "rock on girl!" vibe, it feels so cozy yet lively.
