I don`t have much time right now, have to be heading out in a few minutes, but I will just answer a few points.

I generally discourage anyone who wants to acquire good Japanese language abilities from studying in Tokyo. Tokyo is sort of it`s own little country, and there are SO MANY MORE English speakers there. They`re everywhere. While you may feel that you`re determined to learn Japanese, it always seems like in the end everyone takes the path of least resistance... And ends up hanging out with foreign friends, speaking English, and not immersing themselves in Japanese culture to any extent at all. There are people living in Tokyo for more than 10 year who cannot speak more than a few words of Japanese. It`s easy to make a bubble there and never leave it.

And that`s on top of just generally being expensive, crowded, and hectic.
A plus, I assume, is that there are more things in general in Tokyo - more events, more shops, etc. However, when I spent some time in Tokyo the sheer frustration of the city drove me crazy. Obviously my opinion is just that, an opinion, but Tokyo is "Tokyo", and not "Japan".

As for Nagoya - it`s a big city, but has wide roads, a large number of *green* parks. (Sure, Tokyo has parks, but not nearly as many with TREES)... Large sidewalk areas - Nagoya is actually one of the only cities in Japan where it is legal to ride your bicycle on the the sidewalk, and everyone does. There is more than enough space. Driving through Tokyo, I`d have to constantly brake to avoid killing people who were walking and riding their bikes in the street. It`s cheap to live here, and there is plenty going on. It`s also between Osaka and Tokyo, so it`s not hard to go there. Head north, and there is a ton of countryside... I personally love Nagoya, and wouldn`t choose to live anywhere else (Well, I don`t actually live in Nagoya right now, but close enough.). Tokyo had me feeling seriously sick after a week.

I guess it`s really up to the type of person you are. If you like to go out all the time and be constantly busy, and don`t mind everywhere being incredibly crowded and hectic... You`d probably like Tokyo.
If you want to live a relaxed life, enjoy the rest of Japan, and have all the amenities of a big city available to you without having to fight for them, then Nagoya would be a better place.

Of course, I`m totally biased. But the stuff about English speakers in Tokyo is completely true.
