Notes

1. 5000 - Got me a bit worried at the beginning as I ran into a dead end going south and the place didn't really look friendly for guessing but going north quickly brought me into a decent looking town with signs mentioning some local places, station but most importantly it mentioned Tokushima, quick zoom in and I decided to follow along the railroad going south from Tokushima. Soon after I noticed Yuki station (Yuki was mentioned on signs) and Hiwasa station (station itself was on the signs). Still had some time left and tracking back wasn't too hard (short distance, recognizable shore, spot right over a river)

2. 5000 - Quickly got to the main road and noticed Sakai on the signs which I vaguely recognized. Decided to keep going and soon after noticed Osaka-Minami in name of one of the local institutions which made it super easy, quick zoom onto Osaka to look for crossing of national 170 and 310 that was next to the starting point, 170 was visible on a far zoom and 310 followed soon after (pretty lucky that 310 was right next to the only 170 marker on a far zoom). I found the crossing and initially started looking to the west of it because the turn looked like one from the street view but then I realized that it also does a right turn on the east side and that's where the point was located. Pinpointing was fairly easy. as it wasn't too far from the main road and right before the right turn.

3. 4923 - Fairly straight forward round but I misjudged where I got off of the starting road. Ended up rushing down the mountain and reached national 42 mentioning Kawabe IC near Wakayama. I trailed along Hanwa Expressway and found Kawabe and 42 running next to it, quickly found the exact intersection where I found the signs but I was running out of time and heavily misjudged where the starting road entered prefectural 176 which forced me to just drop my guess somewhere away from national 46.
