The fantastically safe Tokyo metropolis is made up of several neighborhoods, concentrated around subway stations. These are connected mainly by the JR Yamanote ring line, the Ginza Metro line, the Marunouchi Metro line, and the Hibiya Metro line. The main neighborhoods are biz/shopping/nightlife Harajuku/Aoyama/Omotesando, young and trendy Shibuya, rowdy foreigner row Roppongi, upscale Ginza/Tokyo Station/Yurakucho, geeky Akihabara, and historical Ueno and Asakusa. Take a look at the Attractions Overview to get an idea of where to start.
