A samurai was a member of the traditional warrior class. He was a younger paternal cousin to the famous Saigō Takamori. As a protégé of Ōkubo Toshimichi, he helped overthrow the Tokugawa Shogunate. This effort was a major part of the Meiji Restoration. During the Boshin War, he commanded the Detached First Brigade. He also managed field artillery positions on Mount Oda during the Battle of Aizu. During that siege, he was wounded by a local guerrilla force.

To prepare for his military career, Ōyama studied extensively in Europe. In 1870, he traveled to France to attend the École spéciale militaire de Saint-Cyr. While there, he served as an official Japanese military observer during the Franco-Prussian War. From 1871 to 1874, he lived in Geneva to study foreign languages. This period allowed him to become fluent in Russian. He also became the first recorded Japanese customer for Louis Vuitton. After his studies, he returned home to help build the new Imperial Japanese Army.

Ōyama's military command grew through several different wars. During the First Sino-Japanese War, he was the commander-in-chief of the Second Army. His troops landed on the Liaodong Peninsula and captured Port Arthur by storm. They also moved to Shandong to capture the fortress of Weihaiwei. Later, during the Russo-Japanese War from 1904 to 1905, he led the armies in Manchuria. As the Supreme Commander, he had total authority over land operations. He personally directed tactics in major battles like Liaoyang, Shaho, and Sandepu. Even after a brief illness, he returned to direct the Battle of Mukden.

His success led to many high titles and honors within the kazoku peerage system.

Beyond the battlefield, Ōyama had a significant impact on Japanese culture. In 1869, a British instructor suggested that Japan needed a national anthem. Ōyama, who was well-versed in literature, selected the words for the poem Kimigayo. This poem became the Japanese national anthem. His personal life also connected Japan to the West. His second wife, Sutematsu, was a graduate of Vassar College in the United States.

He even built a large house in Tokyo that was modeled after a German castle.

Ōyama's life ended in 1916 at the age of seventy-five. He was given a state funeral to honor his long career.

His death may have been related to diabetes, as he was a large man who enjoyed big meals. His legacy remains tied to the modernization of Japan's military. He helped transition the nation from a feudal society to a modern global power. His influence can still be seen in the history of the Imperial Japanese Army.
