Yamamoto Sayaka stars in Mos Burger's new CM for 'Manhattan Clam Chili Roast Katsu' that's scheduled air on September 17. 

This is Yamamoto's first time starring in a CM after beginning her solo activities. In the CM, you can hear her new song "Ai Nante Iranai" as she delivers the catchphrase "Eat well to work hard." She plays the role of a woman who writes songs at home, then eats a hamburger to satisfy her hunger. The interior decoration used in the CM is based on Yamamoto's actual workplace, and her own guitar makes an appearance as well.
