A Relic of the Boshin War 戊辰戦争の遺跡

The Boshin War pitted loyalists of the Tokugawa shogunate, which had ruled Japan during the Edo period (1603–1867), against factions allied with the Imperial Court. Each side had different visions for the future of the nation, particularly with regard to Japan’s foreign relations and the pace of modernization.

The samurai of Aizu, known for their martial prowess, were allied with the shogunate. Matsudaira Katamori (1836–1893), the daimyo of Aizu, sent his men to fight against imperialist forces in Kyoto when the first battle of the Boshin War broke out in January 1868.

Conflict descends on the Aizu-Numata Kaido

As support for the restoration of imperial rule grew, the daimyo of various domains relinquished their territories and pledged allegiance to the emperor. However, some still favored military rule, and shogunate loyalists in the Aizu region, including samurai, hunters, and farmers, formed a coalition. In July 1868, the coalition traveled on the Aizu-Numata Kaido to fight imperialist forces in Tokura, in the village of Katashina. Small reconnaissance teams from both armies patrolled the Sanpei-toge Pass and Lake Ozenuma, occasionally engaging in minor skirmishes.

The coalition of shogunate loyalists was victorious in Tokura. However, the decisive Battle of Aizu took place in the autumn of the same year. The imperial army besieged Tsuruga Castle, the stronghold of Aizu and the seat of Matsudaira’s power, with foreign guns and cannons. Around 5,000 people sheltered in the castle for a month before Matsudaira finally surrendered.

Aftermath

The Boshin War was an important phase of the Meiji Restoration, which ushered in an era of rapid modernization and industrialization. The samurai of Aizu are famous to this day for their bravery and determination in the final years of the Tokugawa shogunate.
