Danny Choo has another great series up on his website and it's perfect for Soyokaze reference images! Danny Choo does a lot of traveling through Japan and takes many fantastic photos along the way. His PLACES TO VISIT IN JAPAN page has a photo essay on KAWAGOE, JAPAN and it has the exact look and feel that I want for Soyokaze.

It looks like I may need to invest in many more people, however. The place looks packed! :)
