I'd like to the an analysis using historical economic data of Japan and Germany. For that I'm trying to figure out, if data exists from before 1945 of economic production in different japanese and german cities. I'd like to find some measure to, for example, compare the industrial output of Kyoto and Hiroshima from 1935 to 1945.
Does anyone know, if such data exists and where I would start searching for it?
I found this Wikipedia article about Industrial Production in Shōwa Japan but it lacks any citations.
Most promising would be the book Historical Statistics of Japan. However, I can't seem to find it online or in my library. Buying it from Japan for a high price isn't worth it to me, since I'm not even sure if the relevant data is inside.
Any help would be greatly appreciated!
