I will post/update the maps as I find them or when I get some time to do so. You will have likely come across these already but this is just for the sake of having most or all of the mapped stuff in one space. Please keep the discussion relevant to resources, findings, etc.

Big thank you (ありがとうございます) to the people who have spent the time to document all of this, it's immensely helpful to everyone. Sources (that I know of) are listed at the bottom of the post.
