Ōmura Masujirō

Ōmura Masujirō (1824-1869) was a scholar of military science and military system reformer from the Chōshū domain during the late Edo and early Meiji periods, known as the "Father of the Meiji Army." Mastering Dutch learning and Western military science, he took command of military operations for the new government forces during the Boshin War, employing modern tactics to achieve overwhelming victory against the Tokugawa shogunate's army.

Ōmura was born the son of a village doctor in Suō Province (present-day Yamaguchi Prefecture). He studied Dutch learning at Ogata Kōan's Tekijuku in Osaka, and subsequently conducted serious research into Western military science through the Dutch language in Nagasaki. While initially supporting himself as a Dutch-style physician and continuing his research in military science, he eventually entered the service of the Chōshū domain amid the late-Edo upheaval and undertook the task of introducing Western-style military organization.

Ōmura's true capabilities were displayed during the Boshin War (1868-1869). Against the old shogunate forces centered on the Ōuetsu Reppan Dōmei alliance, Ōmura deployed modern operations centered on Western-style artillery and rifles. He led the new government forces to victory through outstanding generalship in the Battle of Aizu and the Battle of Hakodate as well. After the Meiji Restoration, as Vice Minister of the Military Department (equivalent to the subsequent Vice Minister of the Army), he led the construction of Japan's modern military system and laid the foundation for conscription.

However, in Meiji 2 (1869), he was slashed by members of the old samurai class who opposed his reforms at his lodgings in Kyoto, sustained serious wounds, and died approximately two months later. He was 46 years old. His death was an event that symbolized the historical turning point between the end of the age of the samurai sword and the beginning of the modern military.

In the realm of Japanese swords, Ōmura's life is ironically positioned as that of "the man who announced the end of the era of the sword." The modern military system he promoted valued collective tactics with rifles and cannons over individual valor with the sword, and the Japanese sword—the symbol of the warrior's soul—was disappearing from the battlefield. Yet despite this, Ōmura himself died by the sword. This paradox inscribes an unforgettable page in the history of the Japanese sword. At the Yasukuni Shrine approach in Ueno, a bronze statue of Ōmura stands with a sword at his side in military dress.
