Kochi Prefecture 2027: Shimanto, Katsurahama + Yosakoi Guide

Kochi is Shikoku's biggest and emptiest prefecture — mountain spine down the middle, Pacific crashing against the south coast, straw-seared bonito served with four kinds of garlic. It is the one Japanese prefecture that still feels like a small country.

Quick facts: Kochi 2027

History + what makes Kochi special

Kochi occupies Shikoku's entire southern coast. Kochi Castle (built 1611, mostly original) sits in the capital — one of only twelve original wooden donjon in Japan. Katsurahama Beach, 20 min from the city, holds a 5.3-m bronze of Sakamoto Ryoma, Kochi's local-born samurai who negotiated the 1868 Meiji Restoration. Further west, Shimanto River runs 196 km through hills untouched by major dams — Japan's 'last clear river' and best for canoeing. Kochi's cuisine centres on katsuo no tataki — bonito seared tableside with burning rice straw, 20 seconds a side.

• ●Kochi Castle (high-category original) — Both the keep AND the main gate are originals from 1611, unique in Japan.
