I was about to delete "way/58240051" located here, as its unusual tag waterway=old_river, in many cases, found to be duplicated rivers/streams, likely leftover from around year 2010. However, in this case, judging its shape and the terrain in this area, it could still exist as a culvert (暗渠). Therefore I'm leaving it as is, and it would be great if someone with knowledge or can do a survery here to tag it properly.

The bus route (relation #19313676) is broken. I managed to fix other issues, but it still lacks its first bus stop (豊田市) and some of its way segments in the beginning.
