There was some 25 year old Japan government GIS data they imported for the woods outlines that looks like it has about a 20-30m accuracy, and has some wild offsets compared to the road data. 

The biggest problem is that i live on the edge of the wilderness, and the outline is a giant relation or something - and i end up breaking it sometimes. 

Some mappers in some prefectures deleted them all, deeming there were no "woods" - so the region looks really odd compared to the rest of Japan. 

Thanks for the feedback guys.
