Hiroshi Ōshima was a high-ranking general in the Imperial Japanese Army.

He also served as the Japanese ambassador to Germany during World War II. An ambassador is a diplomat who represents their nation to a foreign government. Ōshima played a complex role in history. He worked to strengthen the alliance between Japan and Nazi Germany. However, he also became an accidental source of vital information for the Allied powers. General George C. Marshall called him the main basis of information regarding Hitler's intentions in Europe.

Ōshima was born into a provincial, low-ranking samurai family in Gifu Prefecture. His father rose through the military ranks to become the Army Minister from 1916 to 1918. Because of his family background, many people expected great things from the young Ōshima. He graduated from the Imperial Japanese Army Academy in June 1905. He moved quickly through the military ranks. He became a second lieutenant in 1906 and a lieutenant in 1908. By 1916, he had reached the rank of captain. He also served in Siberia and worked in various European cities like Budapest and Vienna.

In 1934, Ōshima moved to Berlin to serve as a military attaché. This is a military officer who serves in an embassy. He spoke German almost perfectly. He became close friends with Joachim von Ribbentrop, who was a top foreign policy advisor to Adolf Hitler.

Under Ribbentrop's guidance, Ōshima met privately with Hitler in 1935. He was promoted to major general in March 1935. By October 1938, he was appointed the ambassador to Germany. He helped forge important agreements like the Anti-Comintern Pact in 1936 and the Tripartite Pact in 1940. These pacts were designed to create a stronger connection between Japan, Germany, and Italy.

During his time in Berlin, Ōshima had incredible access to German leaders. He was a personal confidant to Hitler. This gave him access to German war plans and national policy. His access was compared to that of Winston Churchill with American leaders. He visited places like the Eastern Front and the Atlantic Wall to observe German defenses.

He was so highly regarded by the Nazi leadership that Hitler awarded him the Grand Cross of the Order of the German Eagle in Gold.

This was a rare honor given to only 15 people.

Ōshima was a very meticulous officer. He wrote detailed reports about everything he learned in Germany. He sent these reports back to Tokyo using a special radio system. They used a diplomatic code called the Purple cipher.

Ōshima believed these messages were completely secure. He even thought he had used double-encryption to protect them. However, American codebreakers had actually broken the Purple code in 1940. They used the intercepted messages as "Magic" intelligence. This allowed Allied leaders to read Ōshima's reports almost at the same time as the Japanese government. Sometimes, the Allies even read them before the Japanese did.

The amount of information the Allies intercepted was massive. In the last 11 months of 1941, they intercepted about 72 dispatches. In 1942, they intercepted 103. This number grew to 400 in 1943 and 600 in 1944. In the final months of the war in 1945, they intercepted about 300 more. This intelligence was incredibly valuable for the Allied war effort. It helped them understand the movements and intentions of the Axis powers. Ōshima never knew that his most secret messages were being read by his enemies.

After World War II ended, Ōshima faced legal consequences for his actions. He was convicted of war crimes at the Nuremberg trials. The court focused on his role in creating the pacts used to wage aggressive war. He was also aware of and participated in discussions regarding harsh actions against prisoners. He was sentenced to life imprisonment. However, he was later released on parole in 1955. He died before the full truth about the Purple code decryption became common knowledge.
