Kiiyan, Kaji Yuki and Shimono Hiro have done a series of commercials for Riken Vitamin’s wakame (seaweed) soup mix based on the idea of promoting the soup to parents and children together.

Each seiyuu has voiced three ads:  mom, dad and child. The videos, plus comments from each of the seiyuu and recipes for the dishes in their commercials can be found on the Riken site here.

And here are Kiiyan’s CMs:

Mom

Dad
