Public Transport in Japan

One think that i love in Japan is the public transport. Here, the transport are really fast and practical compared to Europe. The only thing is that here the transport is really expensive. For example: in Paris, you pay the price for one ticket, that is almost approximately 250 yen (2€) but then you can take all type of transport for one hour and a half. Anyway I still prefer the Japanese public transports because they are way better!
