^ In a sense, no, it doesn't matter. Perhaps we can ask whether a sushi master is trained in Japan or not.
It is hard to find a japanese sushi restaurant / bar where the masters extoll the traditions of sushi making. I can relate in getting frustrated with the so called japanese restaurants where the sushi/sashimi are just manufactured by a supposed chef without much craftmanship and care for the product.
Along with Cafe Miche, which I highly recommend, you may also want try Zen, 2803 Eglinton Avenue East. I haven't been to this restaurant but I hear you have to sit at the sushi bar and talk to the sushi masters in order to really get the good stuff.
And tell us how the food was if you decide to go!
