Information on the scenic railways of Japan

My interest in railways is generally more about seeing and appreciating a country's natural beauty than any appreciation of the history or cultural value of those railways. In the case of Japan, such people might be interested in these sites I found:
1. Scenic values
2. History of Japan railways
3. Photos of Japan railways

I was very impressed by the scenic beauty of Japan's railways. The Japan Rail Pass gives tourists a great opportunity to appreciate the country.
