Mackerel Road connects Wakasa, which overlooks the Sea of Japan, and Kyoto. Wakasa, located in Fukui Prefecture, has a sawtooth-shaped coastline, and is a treasure trove of excellent seafood. The region, known as a land of food, has been offering up its cuisine to the emperor since the 7th century. In the 17th century, the mackerel transported to the capital from Wakasa supported the capital's food culture through dishes like mackerel sushi, an essential part of summer festivals. It's said that by the time the mackerel arrived in Kyoto, it was at just the right level of saltiness. We visit Mackerel Road, which winds through beautiful mountain villages, connects people, and has passed along both culture and customs.
