i used the JR Pass when I was in Japan. 14 days, traveling between Tokyo, Kyoto, Osaka, and Nara. It was well worth it. Keep in mind though that local trains and subways are privately owned, and the pass only works on JR train lines --which means it's of great use city to city, but within cities, you'll just be paying cash.
The easiest way to do this is to just tally up the cost of trips from one city to the next, and see if it comes out to be more or less than the cost of a pass. for me, it was a good value.
Yeah, I agree...just depends on how many cities you're going to and if it adds up or not.
Also, there are different types of JR passes. I know there is a "regular" pass and a "Green" pass. Regular, I believe, is like unreserved seats and can be crowded. Green seats are much quieter and you reserve your seats (can be done just before you get on). Green is more expensive of course.
We had green passes and went to several cities in Japan. It was great I thought. We got the passes on advice from the Japanese fellows my husband was meeting with...
