Visiting Tokyo

Hey Japanophiles! I'm heading off to the Land of the Rising Sun in a month and have been doing my fair share of research. I've found the cheapest way of getting to Akihabara, gotta love those maid cafes, from Narita airport. It's called the Wa-shoi! Bus and it's free, I kid you not!! My friend in Tokyo found out about it and let me know. Seems like you have to log onto http://wa-shoi/bus/, become a member, do general community site stuff, and they give you points which help you get a ride on the bus. This thing can save you about $25 one-way and that is a lot of ramen and mochi balls. I have my ride from Narita to the Maid Cafes all set!!
