Best Japanese garden outside of Japan
The Buenos Aires Japanese Gardens is a unique place in Buenos Aires (actually I get the impression that everything in Buenos Aires is unique). It is a private garden (entry fee is 50 pesos) that will transport you all the way to Japan. It is without a doubt the most beautiful Japanese garden I've seen outside of Japan. In the center is a lake with an island which you can access by a traditional Japanese bridge and there are trees, paths, and a teahouse where they offer green tea and dorayaki served in the traditional way by a staff dressed in kimonos and yukatas. I think they also hold tea ceremonies here sometimes.
