413 — 八王子市 to 御殿場市
Japan · measured from OpenStreetMap geometry
413 runs 25 miles between 八王子市 and 御殿場市. We counted 1,044 corners along it, which works out at 41.8 a mile — corner after corner with no let-up. It runs past mountain peaks, a river, a mountain pass and woodland. That is calmer than two thirds of the roads we have measured in Japan, where the median is 53.1 a mile.
Ridden together with 521 and D10 it makes about 34 more miles of the same kind of road.

How we measured it
Corner counts come from the road's own geometry in OpenStreetMap, not from ratings or votes. Every bend above a threshold of curvature is counted once, so two roads can be compared directly. Nothing here is crowdsourced and nobody paid to appear.
