The track is near Nagoya AFAIK, a few hundreds kilometers to the south of Tokyo. I seriously do not think region was touched at all by the tsunami. And the damage sustained by the quake itself must be minimal, you can clearly see that the damages in Tokyo aren't THAT much important, though being a lot closer to the epicenter.
Brendan, I've done some researchs, and I think it's a fair bet to assume that Sugo was touched massively, as it is located in Sendai's region. Hard to say for sure for most of the others well known tracks, most of them are a lot further from the epicenter.
