Based on that info it doesn't look like you are limited to only the one line but I could be mistaken. Maybe try contacting your travel agent or whoever you are planning to get your rail pass through to see if the limitation really exists.JR West-Sanyou Pass
Excursion Pass for the Osaka-Okayama-Hiroshima-Hakata Area.
This pass can be used in the ordinary-class cars for 500-Series "Nozomi" and other Sanyo Shinkansen trains (reserved or non-reserved seats) while traveling in the Sanyo area to such famous sightseeing locations as Osaka, Okayama, Hiroshima, and Hakata.

Those maps are amazing. That's exactly what I was hoping for. The ryoko site looks especially helpful, and having PDF files will really help me with planning, as I can print out a hard copy.http://www.ryoko.info/rosen/train/

I don't know of any one central place for _all_ the information you're asking.Hi All,
I realise that their are many JR and private railways, but I was wondering if there was a exclusive map anywhere that might be primarily for railway travel.
Well I want to do some good research into what I really want to see and do. Obviously I have to determine where I can go and how much time I will stay in an area. It may turn out to be impractical to travel to far if I am missing out on enjoying the sites.I don't know of any one central place for _all_ the information you're asking.
My suggestion is to get the longest JR pass you can get and refer to the overall JR map here. Even with that, your transportation is going to cost a bomb.
Anyways, what I would do with the map is to first identify the more major cities I will pass through. Then I will look up interesting places in/surrounding these cities. As convenient and well-networked as it may seem, it is not unusual to wait 2 hours or so for the next train in the more rural places (even though the trains were run by JR!). Trust me, you do not be out in the cold for hours on holiday waiting for some local train/bus just to visit/get out of one "must see" attraction. Much less in the cold of winter.
I don't know how much time you have but I've done a trip looping Tohoku in 1 month with my start/end point in Tokyo. It was extremely tiring to say the least. I don't know how long I would need if I were to loop the whole of Japan!
Good luck! And I wish I could do it too.
