Why we send people here

A thousand years of paper and six hundred of blacksmithing — Tosa washi glows and Tosa knives outlive their owners. Both pack flat and clear customs.

Why it earns the hours
  • It is not only a photo stop: a thousand years of paper, six hundred of forging, in a province of forest and water.
Before you count on it
  • No single published ride covers this one. Budget for a taxi both ways, or fold it into a guided day.
The story

Why Tosa washi & forged knives is famous

A thousand years of paper, six hundred of forging, in a province of forest and water

Tosa washi is paper made here for over a thousand years, including tengujoshi, at one point the thinnest handmade paper in the world and still used by museums to repair documents. Tosa forged blades were shaped by the same domain's demand for farm tools, and the smiths still make knives to order.

Kochi is 84% forest — the highest of any Japanese prefecture — with fast clean rivers running through it. That single fact produced both the thinnest handmade paper in the world and the knives Japanese farmers have used for six centuries.

The Sunday Market is the ideal place to buy both — direct from makers. Otherwise the Obiyamachi arcade and the products hall near the castle.
