Sakamoto Ryoma

The low-ranking samurai who talked two enemies into ending an era

In one paragraph

He held no office, commanded no army, and was murdered at 31 — a month before the shogunate he helped topple actually fell. Japan has been in love with him ever since, and nowhere more than here.

Every Japanese person knows the face: the rumpled kimono, the boots worn with it, the hand inside the lapel. Sakamoto Ryoma was born in Kochi in 1836, into the gōshi — the lower rank of Tosa samurai, tolerated by the upper rank and never quite accepted by it. That resentment shaped everything he did.

He left the domain illegally in 1862, which was a capital offence, and spent the rest of his short life as a man with no official position moving between people who were supposed to be killing each other.

What he actually did

Two things, and they were enough.

First, in 1866, he brokered the Satchō Alliance — an agreement between Satsuma and Chōshū, domains that had been open enemies. Neither would talk to the other; both would talk to him. The document was signed in secret in Kyoto, and at Chōshū's request Ryoma endorsed it on the back in vermilion ink as guarantor. That alliance produced the army that ended the shogunate.

Second, he is credited with the Eight-Point Plan of 1867, said to have been drafted on a ship. No copy in his hand survives, and some historians think it was written up later. It is a sketch of a post-shogunate Japan with a bicameral assembly, a constitution, a navy, and treaties renegotiated on equal terms. Much of the Meiji state that followed looks remarkably like that document.

He also founded what is generally called Japan's first modern trading company, and used it to move weapons between the domains he was busy reconciling.

The murder

On 10 December 1867 — his thirty-first birthday by the old reckoning — assassins found him at the Ōmiya inn in Kyoto and cut him down along with his friend Nakaoka Shintarō. The killers have never been definitively identified. The shogunate's police unit is the usual suspect; other theories implicate the very domains he had allied.

The shogun had already handed power back to the court a month earlier. The decree that abolished the shogunate outright came three weeks after his death. He did not live to see the country he had sketched.

Why Kochi cannot let him go

Because he is the perfect Tosa story: a low-ranked man from a peripheral province who changed the country by refusing to accept his position in it, and who then died before he could be corrupted by success. Japan loves the noble failure; Kochi loves the outsider who was right.

His bronze statue stands on Katsurahama beach, 13 metres tall including the plinth, facing the Pacific he wanted Japan to sail out into. It was erected in 1928 by public subscription, largely raised by local students. For some weeks most years a platform is built beside it so visitors can stand at eye level with him. In 2026 it is up from 12 September to 23 November.

Seeing it

The statue at Katsurahama is the closest sight to the ship: 10–15 minutes by taxi from the cruise terminal, about ¥2,150 (¥1,840 before 30 November). From the city centre it is about 30–50 minutes by the MY-YU bus or the Tosaden Katsurahama line. In the city, the Kochi Castle grounds and the Sakamoto Ryoma Memorial Museum at Katsurahama cover the history properly. The birthplace is marked by a stone in a residential street, which is quietly the most affecting of the three.

Katsurahama is a short taxi from the ship, 10–15 minutes and about ¥2,150 (¥1,840 before 30 November). No tour is needed for it; book the return pickup before you get out. The castle and the city museums cover the rest of the history.

Quick answers

FAQ

Who was Sakamoto Ryoma?

A low-ranking Tosa samurai from Kochi who brokered the 1866 alliance between Satsuma and Chōshū — the arrangement that produced the army that ended the shogunate — and is credited with an eight-point sketch of a post-shogunate Japan. He held no office, was assassinated in Kyoto at 31 in December 1867, and his killers were never definitively identified.

Where is the Sakamoto Ryoma statue?

On Katsurahama beach, facing the Pacific. It is 10–15 minutes by taxi from the cruise terminal (about ¥2,150; ¥1,840 before 30 November), or about 30–50 minutes from central Kochi by the MY-YU bus or the Tosaden Katsurahama line. It stands 13 metres including the plinth and was funded by public subscription in 1928, largely raised by local students. No tour is needed: book the return taxi before you get out.

Why is Ryoma so famous in Japan?

Because he changed the country without rank, army or office, and died before success could compromise him — the archetype Japan finds most compelling. Kochi in particular claims him everywhere: his silhouette is on manhole covers and sake bottles, and the prefecture renamed its airport Kochi Ryoma Airport.
