Mamma Mia! opened Dec. 1 at the Umi Theater, the first production to play the 1,200 complex, built by one of the world’s largest advertising conglomerates, Dentsu Inc..

Co-starring with Hosaka are Izumi Mori and Yayoi Aoyama as Donna's bosom buddies (and rockin' Dynamos) Tanya and Rosie (pictured below with Hosaka).

Mamma Mia! collects a couple dozen hit songs by the Swedish supergroup ABBA and shapes them around the story of a single mother (Hosaka) and her young daughter's marriage on a Greek isle. While the daughter plans her future with the love of her life, she and her mother are haunted by three different men who may or may not be her daughter's father.
