Absolutely fantastic, the voices were incredible even though some of the softer tones were drowned by te orchestra, but I can't blame them since the space was so reduced.
Technical errors were very few but I mention them for the next performance.
1. The cover (hat-cap) of an officer can not be placed facing up because the top will get dirty.
2. The Japanese women were walking like westerners instead of dragging very short steps in their kimonos.
