Takarazuka Revue

I'm staying at a hotel in Takarazuka on business trip.
Takarazuka city is very famous of the hometown of "Takarazuka Revue".
Takarazuka opera company is an opera company in Japan whose members are all females.
It consists of five groups, "Flower", "Moon", "Snow", "Star", and "Sky".
All performers graduate from Takarazuka music school.
They are called "Takarasienne".
