Most educated people in Tokyo speak “standard Japanese” which is acceptable in business situations and for TV broadcasters etc.
People from regions outside of Tokyo might speak in their regional accent among friends from the same region – but they try to adapt their accent to “standard” Japanese when they talk with people from other areas. Japan actually has schools that train Japanese TV announcers in the standard Japanese accent and the proper way to talk on TV.

There are a couple of major exceptions to this pattern — Before the 17th century, Kyoto Japanese was considered to be “standard” Japanese. Perhaps for this reason, people from Kyoto generally make no effort to disguise their Kyoto accents — The Kyoto accent is considered to be quite classy.

In areas close to Tokyo the accent is pretty close to Tokyo Japanese but there are some minor differences. For example, people from Ibaraki often pronounce “K” as “G” (so they pronounce Ibaraki as Ibaragi).

Personally I love the way Kyoto people speak. Their dialect is very different and sounds very spacial to me, but unfortunately that is not standard…

As others said, the standard is Tokyo. I have never heard news in other dialects other than the standard one. However, If you are interested, you can go to Kyoto to learn Kyoto dialect.

If you are planning to go to a language school to learn Japanese, I am sure that the school will teach you the standard one. So at school you learn the standard and outside the school Kyoto dialect. How about that? It may be more fun to learn 2 ways of speaking Japanese!
