|Died||February 7, 1885 (aged 50)|
|Known for||Founder of Mitsubishi|
Iwasaki was born in a provincial farming family in Aki, Tosa province (now Kōchi Prefecture), the great-grandson of a man who had sold his family's samurai status in obligation of debts. Iwasaki began his career as an employee of the Yamauchi clan. The clan had business interests in many parts of Japan.
Iwasaki left for Edo (now Tokyo) aged nineteen for his education. He interrupted his studies a year later when his father was seriously injured in a dispute with the village headman. When the local magistrate refused to hear his case, Iwasaki accused him of corruption. Iwasaki was sent to prison for seven months. After his release, Iwasaki was without a job for a time before finding work as a teacher.
Returning to Edo, he socialised with political activists and studied under the reformist Yoshida Toyo, who influenced him with ideas of opening and developing the then-closed nation through industry and foreign trade. Through Yoshida, he found work as a clerk for the Yamauchi government, and bought back his family's samurai status. He was promoted to the top position at the Yamauchi clan's trading office in Nagasaki, responsible for trading camphor oil and paper to buy ships, weapons, and ammunition.
Following the Meiji Restoration in 1868, which forced the disbandment of the shogunate's business interests, Iwasaki travelled to Osaka and leased the trading rights for the Yamauchi clan's Tsukumo Trading Company. The company changed its name to Mitsubishi in 1873.
Iwasaki became president of Mitsubishi in March 1870. The name Mitsubishi is a compound of mitsu ("three") and hishi (literally, "water chestnut", often used in Japanese to denote a diamond or rhombus). Its emblem was a combination of the Iwasaki family crest, showing three overlapping lozenges, and the crest with three oak leaves, arranged in a threefold rotational symmetry, of the Yamauchi family, which controlled the part of Shikoku where Yatarō was born.
In 1874–1875, Iwasaki was contracted by the Japanese government to transport Japanese soldiers and war materials. The Japanese government purchased a number of ships for the Japanese Expedition of 1874 to Taiwan against Paiwan Aborigines in southeast Taiwan, and these ships were later given to Mitsubishi after the expedition was finished in 1875. This created strong links between Mitsubishi and the Japanese government that ensured the new company's success. In return, Mitsubishi supported the new Japanese government and transported troops who defeated the Satsuma Rebellion in 1877. Thus the success of Mitsubishi became intertwined with the rise of the modern Japanese state.
Subsequently he invested in mining, ship repair, and finance. In 1884 he took a lease on the Nagasaki Shipyard, which allowed the company to undertake shipbuilding on a large scale, and renamed it Nagasaki Shipyard & Machinery Works.
Iwasaki Yatarō often gave dinners for dignitaries, spending a huge amount of money on these occasions, but he also made many friends who later helped him by doing favors.
Iwasaki died of stomach cancer aged 50, and was succeeded as the head of the family business first by his brother, and later his son, Hisaya. His fourth daughter, Masako was married to the first post-war prime minister, Baron Kijūrō Shidehara.
Iwasaki serves as the secondary protagonist of the 49th NHK Taiga drama, Ryōmaden, focusing on his activities during the Bakumatsu, and also serves as the framing narrator of the story. He is portrayed by Teruyuki Kagawa.
