The world population in this map is just under 2 million. I included a whole lot of towns and placed them all by hand as accurately as I possibly could. The map features several urban areas, both near the coastlines and hidden deep within the mountains. Some islands also have cities on them, so if you want, it is possible to create a ferry between them. Originally I only planned to make a map of Chubu, a region of Japan, but I accidentally happen to have included most of Kanto and Kansai, most notably Tokyo and Osaka, thanks to which it is completely possible to recreate the Tokaido Shinkansen. Aside from the Tokaido Shinkansen, the Hokuriku Shinkansen and the Joetsu Shinkansen (which apparently doesn't even touch Joetsu...) can be recreated thanks to the convenient size of the map.
Whilst I did my best to recreate the location of the towns and cities as accurately as possible, that might not be completely true for the cities, as I let the algorithm sort that out, I only made sure that Tokyo, Osaka, Kyoto and Nagoya would be just a bit bigger than the rest.
The map starts in 1880, 9 years after the formation of the first Japanese Railway Company.
Images: Heightmap: I got the SRTM files from this website: http://dwtkns.com/srtm/ as I couldn't get the Google Earth thing working. So, if you also can't get the GE thing working, try that, it's got a nice globe and stuff.
Scenario:
I've made two scenario downloads, one with the Japan Set trains (and TIAS) and one with 2cc (and MMT):
