A submission to the September 2011 J-Festa with the theme “Events in Japan“.

The Namamugi Incident was a samurai assault on foreign nationals in Japan on September 14, 1862, which resulted in the bombardment of Kagoshima in 1863, during the Late Tokugawa shogunate. It started out with a samurai attack on British nationals, ended up with the British engaging war on a province of Japan and has an interesting side piece on how the Japanese national flag was adopted.

Charles Lennox Richardson, a British merchant and his three companions were travelling along the Tōkaidō road through the village of Namamugi. On the road they passed a 1,000 man procession of the daimyō (feudal lord) of the province of Satsuma, Shimazu Hisamitsu. The custom at the time was to stop and dismount when passing a daimyō as it was not permissible to overtake somebody with such a high status. Richardson and his crew apparently ignored the custom and refused orders. This was viewed as disrespect of the daimyō so the party were attacked by Shimazu’s guards. Richardson was killed and two of his companions seriously injured.

In response, the British government protested and demanded restitution for the attack on British nationals from both the Government and from the Daimyō of Satsuma including the arrest and trial of the perpetrators of the outrage. The Shogunate were quick to capitulate and indemnified Britain for the loss paying a large bounty. However, the daimyō remained defiant refusing Britain’s demands. He argued that under Japanese custom disrespect to a daimyō was sanctioned by the immediate death of those showing disrespect. Legally, this claim was invalid, as foreigners in Japan benefited from extraterritoriality (the state of being exempt from the jurisdiction of local law) meaning that Japanese customary law did not apply to foreigners.

This sparked what is often referred to as the Anglo-Satsuma war. After protracted and fruitless negotiations with Satsuma, a squadron from the British Royal Navy, trying to exact a payment from the daimyō of Satsuma following the Namamugi Incident, engaged the province of Satsuma a year later in a naval bombardment of the city of Kagoshima on August 15, 1863.

The bombardment claimed just five lives among the people of Satsuma, and 13 lives among the British. Material losses were more considerable with around 5% of Kagoshima’s urban area ravished by fire and a number of Satsuma’s steamships destroyed.

Each side recorded the result as a victory. Satsuma’s claim was that the British did not land troops or seize cannons. Nevertheless, the show of British military prowess appeared to impress Satsuma as following the conflict Britain and Satsuma developed closer relations and became major allies.

Bits and pieces

  • Namamugi, meaning “raw wheat”, is a neighbourhood of Yokohama. These days the township of Namamugi plays host to the Kirin Brewery Yokohama and raw wheat is, of course, an ingredient of beer.

  • The hinomaru, flag of Japan

    During the Bombardment of Kagoshima the Satsuma fleet fought under a flag with the hinomaru design. Hinomaru, meaning “sun disc”, has a white background with a large crimson red circle set in the middle. The British who saw the flag assumed it was the Japanese national flag. Word spread and the flag became internationally recognised as the flag of Japan.

  • The 1993 historical fiction novel by James Clavell, Gai-Jin, is loosely based on the Namamugi Incident.

  • “Nama-mugi, nama-gome, nama-tamago” (raw wheat, raw rice, raw egg) is a famous Japanese tongue twister.
