Iran–Japan relations

Iran–Japan relations (Persian: روابط ایران و ژاپن, Japanese: 日本とイランの関係) are diplomatic relations between Iran and Japan. They were officially established in 1926 during the Pahlavi era. With the exception of World War II, the two countries have maintained a relatively friendly, strong, and strategic relationship throughout history.

Japan's foreign policy and investment with Iran have been significantly influenced by its historically secure demand for energy supplies. Iran is Japan's third most important oil supplier after Saudi Arabia and the United Arab Emirates. Japan and Iran are also cooperating in regional diplomatic relations in the Middle East, such as the reconstruction of Afghanistan and the Israel-Palestinian conflict. The trade balance between Japan and Iran has a significant weight on Iran, and Japan exports automobiles, electrical products, important petroleum products and petrochemical products.

Japanese Prime Minister Shinzo Abe visited Iran in June 2019 to try to mediate between Iran and the United States.
