Kochi
The river that refused to be dammed, the sea where whales still swim, the rebel samurai who helped overthrow the shogunate — Kochi is Japan’s most independent-spirited prefecture.
清流・四万十川、土佐湾のくじら、坂本龍馬の故郷、高知よさこい祭り——高知は日本の自由な魂と豊かな自然が生きる四国最後の秘境です。
Kochi Prefecture covers the vast southern coast of Shikoku, facing the Pacific Ocean with Japan’s most powerful surf and the country’s last truly wild river — the Shimanto, famously undammed. Kochi was the birthplace of Sakamoto Ryoma, the visionary samurai whose alliance between rival domains made the Meiji Restoration possible. The Yosakoi Festival, held every August, originated in Kochi and has since spread to hundreds of events across Japan. Tosa Bay’s deep waters shelter sperm whales, fin whales and dolphins year-round.

Frequently Asked Questions
What is katsuodon and katsuo tataki?
Katsuo tataki (カツオのたたき) is thick-cut bonito seared on the outside over blazing rice straw, served with garlic, ginger and salt or with ponzu. It’s Kochi’s signature dish — the Hirome Market has excellent versions from ¥800.
カツオのたたきは稲わら炎で表面だけを炙った厚切りカツオ。ニンニク・塩またはポン酢で。ひろめ市場で800円〜食べられます。
Can I swim or canoe in the Shimanto River?
Yes — the river is clean and popular for canoeing (¥3,000–5,000 for half-day rentals near Nakamura). Swimming is also possible at designated spots. The famous ‘sinking bridges’ (chinkaibashi) are designed to submerge in floods.
カヌーは中村周辺でレンタル（半日3,000〜5,000円）。川泳ぎも可能。洪水時に沈む「沈下橋」も四万十の名物。
Who was Sakamoto Ryoma?
Sakamoto Ryoma (1835–1867) was a Tosa-born samurai visionary who negotiated the Satsuma-Choshu Alliance that ended the shogunate and launched the Meiji Restoration. He’s Japan’s most beloved historical figure. The Kochi Prefectural Museum and his birthplace in central Kochi tell his story.
坂本龍馬（1835〜1867）は薩長同盟を結び明治維新の礎を作った土佐出身の志士。高知市内に生誕地と龍馬記念館があります。
Travel Tip
Go to the Hirome Market (ひろめ市場) for lunch — order katsuo tataki seared to order at the Yamaichi stall, grab a cup of Tosa sake, and join the communal table. It’s the most authentic Kochi experience, and the bonito is usually still warm from the straw fire.
