Need help to read map! (in Japanese)

Hi!

I read this map http://www.bigboss.jp/tokyo/map.html
which is a guitar shop I want to visit while in Tokyo; I need to know mainly what is the JR station in that map; but the more info from the other things on it the better.

Thanks in advance for the help!

Aerond, the JR station is called 'ochanomizu' (tea water) and is on the Chuo-line in Tokyo. The top side of the map is in the direction of Tokyo station, the bottom side is in the direction of Shinjuku.
The text above Sound Liner says 'Meiji university'. With this information, it should be easy to find but it is always a good idea to print the map so you can ask people. :-)

Thank you very much then; seems it�Ls in the guitar shops area.
