Another Tokyo transit pass
 

This one is good on JR, private rail lines, all subway lines, TOEI busses, and a few other places within roughly the 23 wards of Tokyo. It is Y2,500 for two consecutive days (not much of a deal IMO) and Y3,000 for three consecutive days (possibly a good deal if going to be touring Tokyo a lot).

Here's the detail:

It's available just from Dec 1, 2011, through January 31, 2012. Note that the map is a bit deceiving as it shows some lines in yellow where the pass is NOT valid. It is Suica-like in that you can use the fare gates when within the area of validity. Can only be bought at Narita and Haneda.

I like to take my time while traveling so I didn't do nearly as much as is listed on the visit japan model course. If you already have a JR Rail Pass, the transit pass isn't worth it.

I was in Japan for 9 days, but only had a 7 day JR pass. We explored all the JR accessible areas first, then saved most of the subway travel for the last 2 days. We walked quite a bit and took the subway 4 times a day at most (probably because we didn't have an unlimited pass).

You can buy subway day passes from the ticket machines if there are days you plan to move around a lot. Toei line only is 700 Yen per day. Toei + Tokyo metro is 1000 Yen per day.
