Shikoku Karst Skyline
383Onogahara, Seiyo, Ehime to Tengu Kogen, Tsuno, Kochi
Ridge 'road in the sky' across the limestone grasslands of the Shikoku Karst.
Prefectural Route 383 traverses the Shikoku Karst plateau at around 1400 m, running the ridge past Onogahara, Mezurudaira, Godan and Tengu highlands with grazing cattle and white limestone scattered through rolling green meadows. Nicknamed the road in the sky, it is one of Japan’s 100 most scenic roads and a famed stargazing spot. Some sections are narrow with limited passing, and it closes in winter. Mind the open-range cattle on the road, narrow blind crests, and quick-rolling cloud.
