Notes

1. 5000 - pretty easy round. Got to national 12 with signs for Sapporo and Takikawa to the right, Kitami and Asahikawa to the left. Also on 12 we could see that we came from prefectural 916. Quick zoom onto Sapporo and it didn't take long to find Takikawa and Asahikawa and then T junction we found the signs on, We entered 916 right before a left turn with a bridge over Ishikari so finding the road we came from wasn't too hard. Had quite some time left so I ended up scouting out the starting area because pinpointing itself wasn't that easy, first right in front of us was pretty short and one behind was longer but without a visible turn and there were similar side roads on the map. I dropped my guess more or less in the middle between those two side roads since it felt like a similar distance from a starting point and I wasn't wrong

2. 4993 - Was a bit worried at the beginning but after a while of clicking found a sign mentioning national 4, quick zoom onto Miyagi pref and I started following national 4 north. Soon noticed Hanamaki that was on signs and later Tono and Towa IC. Found a crossing of prefectural 286 and 43 close to IC and followed 43 which we came from. Wasn't sure where we entered 43 so I went back to check if there's a post office on the junction. There wasn't and road layout matched junction that was closer to IC. At this point I was running out of time and guessed somewhere further into the road. Sadly a bit too far, for some reason I thought we did take hard turn left but that was not the case (couldn've just used compass to confirm it, welp)

3. 5000 - Another round that got me kinda worried at the beginning but turned out fairly easy. After a bit of clicking I got to prefectural 74 and turned left where I found mention of Chiba, Sosa and Asahi. Chiba made it easy so I zoomed onto it and noticed the other two to the right of it. Zooming onto those quickly revealed prefectural road 56 that we entered from 74 and that did a 90* right turn. Pretty easy to find so I just went along 56 till I could find 74. Then trailed along 74 but since we weren't on it for long first turn NW was where we came from. I also went back and confirmed that the road we came from was prefectural 114. We entered 114 from a side road and had to click quite a bit to get to where we were so I went back to starting point and headed the other way. As I thought we were really close and starting point was next to a snack bar.

4. 4988 - Started spamming downhill, noted that we are on prefectural 226 and soon reached national 169 with mention of Nara which was a big giveaway. I zoomed onto Nara and found 169 after a while of looking, then traced it untill I found 226, buildings along the road were marked so I got a rough idea of where we started but I dropped my guess too far from the first group of houses, for some reason I thought we took more turns
