John,
I've been to the concerts at the Tokyo Opera City several times, although the hall was completed several years after we moved to Texas. The entire art-district complex in the New Capitol district of Tokyo is one of the numerous culturally-positive leftovers of Japan's bubble economy in the '80s-early '90s. Indeed, Tokyo built a number of truly magnificent facilities in the last 10 years -- all planned during the late bubble era but only after numerous delays due to economy.
And yes, the Opera City is another hall that I know has outstanding acoustics -- arguably the best in Japan. Both the Meyerson and Opera City are so good that I need a
double-blind test in order to decide which is better. Personally, though, I always felt that the Opera City hall had kind of a peculiar visual atmosphere, which I wasn't sure I liked much...
Anyway, I didn't know the name of the principal architect. Hmm... Takahiko Yanagisawa was from the exact same district of Japan where my father was born and this last name is quite common. Perhaps I might be distantly related to him. HAHAHA...
For those who are curious about what we are talking about, here is a photo of the Tokyo Opera City concert hall...
