Definitely sounds like you have done your research. I'm sure, with your skill, the models will not be too hard. As for transportation, I think... well, I don't know, really. It would help if I knew what time period, because I have most definitely not done my research on Japan and all that. If I did, I might have an idea of when Edo was named Tokyo or when shoguns existed. (I know I should remember this stuff from LAST YEAR'S history class )
