He was born in Morioka and graduated from the Imperial Japanese Army Academy, going on to serve in various capacities, including as a military attaché in Berlin and Vienna.

● Early Life and Education

Hiroshi Oshima was born in Morioka in 1886 to a family of Samurai descent. He attended the Imperial Japanese Army Academy in Tokyo, graduating in 1905 alongside other notable figures, including Hideki Tojo and Iwane Matsui. Oshima's education was influenced by his time at the Army War College in Tokyo, where he studied alongside Kazuo Yamamoto and Shigenori Tōgō. He was also exposed to the ideas of Carl von Clausewitz and Alfred von Schlieffen, which would later shape his military and diplomatic strategies.

● Military Career

Oshima's military career began in 1905 when he was commissioned as a Second Lieutenant in the Imperial Japanese Army. He served in various roles, including as a military attaché in Berlin from 1919 to 1922, where he worked closely with Hans von Seeckt and other Reichswehr officials. During this time, Oshima developed a deep understanding of German military doctrine and formed relationships with key figures, including Ernst Röhm and Heinrich Himmler. He also served as a staff officer in the Kwantung Army in Manchuria, where he played a role in the Invasion of Manchuria in 1931 alongside Shigeru Honjō and Jirō Minami.

● Diplomatic Career

In 1934, Oshima was appointed as the Ambassador of Japan to Germany, a position he held until 1939. During his tenure, he worked closely with Adolf Hitler, Joachim von Ribbentrop, and other high-ranking Nazi Party officials to strengthen Japan–Germany relations. Oshima was a key figure in the negotiation of the Anti-Comintern Pact in 1936, which aimed to counter the spread of Communism and Soviet influence in Asia and Europe. He also played a role in the development of the Tripartite Pact in 1940, which formed the Axis powers alliance between Japan, Germany, and Italy, including Benito Mussolini and Galeazzo Ciano.

● World War II and Aftermath

During World War II, Oshima continued to serve as a key figure in Japan–Germany relations, providing intelligence and strategic advice to both governments. He worked closely with Hitler and Ribbentrop to coordinate military strategy and diplomatic efforts, including the Invasion of Poland in 1939 and the Battle of Stalingrad in 1942. Oshima also maintained relationships with other key figures, including Vidkun Quisling and Ferenc Szálasi. After the Japanese surrender in 1945, Oshima was arrested and tried for war crimes by the Allied powers, including the United States, United Kingdom, and Soviet Union.

● Later Life and Legacy

After his release from prison in 1950, Oshima returned to Japan and lived a relatively quiet life in Tokyo. He wrote several books on his experiences, including his time as Ambassador of Japan to Germany and his relationships with Hitler and other Nazi Party officials. Oshima's legacy is complex and multifaceted, reflecting both his significant contributions to Japan–Germany relations and his involvement in the war crimes of World War II. He died in 1975 in Tokyo, leaving behind a legacy that continues to be studied by historians and scholars of International relations, including Henry Kissinger and Zbigniew Brzezinski.
