Morning Musume has revealed a new song "Pyoko Pyoko Ultra!" which will be released on January 25, 2012. The girls wear bright yellow uniforms which really make the setting happy. This song includes the new 10th generation members: Kudo Haruka(11 yrs), Iikubo Haruna(16 yrs), Satou Masaki(12 yrs), and Ishida Ayumi(14 yrs). We wish these girls tons of luck on their new, upcoming song.
