Wakasa Bay — Saba Kaido Mackerel Route Heritage

Wakasa Bay (若狭湾) is a deeply indented coastal region facing the Sea of Japan, historically famous as the terminus of the Saba Kaido (鯖街道, 'Mackerel Highway') — the ancient salt trade route connecting Obama to Kyoto. For centuries, mackerel caught in Wakasa's cold waters were salted and carried 72 kilometers overland through mountain passes to the imperial capital, arriving perfectly cured after 24 hours of walking. This mackerel sustained Kyoto's aristocracy and remains central to Kyo-ryori (Kyoto cuisine) today.

Obama City, Wakasa Bay's historic port, preserves machiya townhouses, temples, and seafood markets unchanged since the Edo period. The morning fish auction at Obama Fish Market (6:00am start) sells the same species — saba (mackerel), wakasa guji (tilefish), and wakasa fugu (pufferfish) — that defined the local economy 400 years ago. The bay's ria coastline creates sheltered coves and fishing villages accessible only by narrow coastal roads, making this one of Hokuriku's least-developed and most atmospheric seascapes.
