When you go to Japan and want to take public transportation you would usually go for the cheaper and more commonly used form of transportation. The one thing is that you will be missing out on the awesomeness which DoCoMo has given to some of the taxis. Some of these visitor taxis will be equipped with wi-fi as will as a PSP in 100 of these taxi’s. You would think that in Japan this wouldn’t make sense since they all have a PSP or at the very least a NDS. There is an upside to these taxis despite the steep rates starting at $8. These taxi’s are cleaner and more sophisticated than normal taxis. It is definitely worth riding at least once if you get the chance.
