41.1Per mile

342 runs 25 miles between 一関市 and 横手市. We counted 1,028 corners along it, which works out at 41.1 a mile — consistently twisty. It runs past mountain peaks, a river, open water and woodland. That is busier than two thirds of the roads we have measured in Japan, where the median is 32.8 a mile.

Ridden together with 342 and 栗駒焼石ほっとライン it makes about 18 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.
