First off, let me just say I'm Singaporean, and damn proud of our Zoo. And it is an award-winning zoo, so we have reasons to be proud of it.
But this is a comparison of two zoos, mainly because I have been to the Ueno Zoo recently (early Nov 2016), and returned to the Singapore Zoo recently (early Dec, 2016) and the impulse to compare and contrast was strong.
Anyway, these are just my impression, and, spoiler alert, I think the Singapore Zoo is much better generally, although there are some good points with Ueno Zoo.
