Overview

Shikoku Karst — Tengu Kogen Skyline (Route 383).

Prefectural Route 383 runs the spine of the Shikoku Karst, a 25km limestone plateau at 1,400m straddling the Ehime–Kochi border — one of Japan's three great karsts and one of its 100 best roads. Nicknamed the road in the sky, it rides a grassland ridge studded with white limestone outcrops and grazing cattle, with the Seto Inland Sea to the north and the Pacific to the south on clear days. Tengu Kogen at the eastern end is a Dark-Sky stargazing haven. Best April to November; watch for cattle and fog.
