The last time Takarazuka came to Singapore was in 1982 which was a very VERY long time ago, according to this Singapore Archives image
Singapore is much better at accepting 'controversial' art performances these days compared to the 80s plus I think we're getting on quite well with Japan. We celebrated 50 years of friendly relations with Japan last year and I think Japan is wanting to do more business or attract more tourists from Singapore to come over because, really, Singaporeans LOVE Japan. So I do hope that they'd consider having a performance or two here.
I know the Takrazuka veterans did a one-off performance at the Lincoln Center in US last year. You lucky people! I would have gone to see it
