Every Sunday morning, the boulevard leading to Kochi Castle becomes a different kind of road. Both lanes are closed to traffic, and for roughly eight hours, some three to four hundred stalls line both sides of a kilometer-long stretch — vegetables, fruit, hand-rolled sushi, deep-fried sweet potato, knives forged in the local tradition, potted plants, ceramics, and the occasional piece of antique lacquerware. The market traces its origin to 1690, when the fourth lord of the Tosa domain formalized a system of street markets in his domain law. The location and day of the week have shifted over the centuries, but the market itself has never stopped. High知 also holds street markets on Tuesdays, Thursdays, and Fridays in different parts of the city. The Sunday market is the oldest and largest — the one that draws visitors from outside the prefecture, but whose real purpose is still what it has always been: a place where local people come to buy local things. Around 17,000 people pass through on a typical Sunday.
