I was there in November so only a month later than you. Weather was PERFECT (for us anyway). Highs of low 20's, most days high teens depending where you were. Not too humid at all. So nice to be on vacation and not be trying to stay cool all the time. Avg temps for Tokyo in October are highs in low 20's high teens, and lows in low-mid teens.This quote is hidden because you are ignoring this member. Show Quote
The JR pass works on most thing that are JR, which can be busses, local trains, and all but the two Shinkansen (bullet trains) listed above. Sometimes the JR line is the fastest or most convenient, sometimes it isn't. This is where the PASMO or SUICA card comes in handy, you just scan in/out at any station and use whatever you want. We didn't use any buses at all except to the airport and the snow monkeys.
