Hello,
During January from the 6th to the 27th I will be staying in Japan, and mostly either commuting in, or to Tokyo on a daily basis. I see that there is a 21 day pass that can be bought. A person that I may be staying with says that it will take me about 40 min to get to Tokyo from there house on the Tokaido line. From there I would be walking into the city. Within the city, going from Shibuya, to Shinjuku, to Harajuku, and other spots, does the JR line also run? Does the 21 day pass cover all of this traveling?
As well, does anyone have an estimate of how much it would cost to get my luggage from Narita to my host's home in Kanagawa, as well as getting myself there? Does the 21 day pass also cover this?
