Indo Japanese Relations:

In the recorded history India's earliest direct contact with Japan was with the Todai-ji Temple in Nara, where the consecration or eye-opening of the towering statue of Lord Buddha was performed by an Indian monk, Bodhisena, in 752 AD.

On 15 August 1947, Japan was among the first nations to recognize Indian sovereignty after its independence from the United Kingdom. A relatively well-known result of the two nations' was in 1949, when India sent the Tokyo Zoo two elephants to cheer the spirits of the defeated Japanese empire.

India refused to attend the San Francisco Peace Conference in 1951 due to its concerns over limitations imposed upon Japanese sovereignty and national independence.After the restoration of Japan's sovereignty, Japan and India signed a peace treaty, establishing official diplomatic relations on 28 April 1952, in which India waived all reparation claims against Japan. This treaty was one of the first treaties Japan signed after World War II.Diplomatic, trade, economic, and technical relations between India and Japan were well established. India's iron ore helped Japan's recovery from World War II devastation, and following Japanese Prime Minister Nobusuke Kishi's visit to India in 1957, Japan started providing yen loans to India in 1958, as the first yen loan aid extended by the Japanese government.

In India, there was great admiration for Japan's post-war economic reconstruction and subsequent rapid growth.Relations between the two nations were constrained, however, by Cold War politics. Japan, as a result of World War II reconstruction, was a U.S. ally, whereas India pursued a non-aligned foreign policy, often leaning towards the Soviet Union. Since the 1980s, however, efforts were made to strengthen bilateral ties.

India's 'Look East' policy posited Japan as a key partner.Since 1986, Japan has become India's largest aid donor, and remains so.

Relations between the two nations reached a brief low in 1998 as a result of Pokhran-II, an Indian nuclear weapons test that year. Japan imposed sanctions on India following the test, which included the suspension of all political exchanges and the cutting of economic assistance. These sanctions were lifted three years later. Relations improved exponentially following this period, as bilateral ties between the two nations improved once again,to the point where the Japanese prime minister, Shinzo Abe was to be the chief guest at India's 2014 Republic Day parade.
