Baron Ijà «in Hikokichi (ä¼ÂéÂÂé¢ 彦åÂÂ, Ijà «in Hikokichi; 22 July 1864 â 26 April 1924) was a Japanese diplomat and politician who served as minister of foreign affairs and Japanese ambassador to the Qing dynasty.

On 4 September 1909, he signed the JapanâÂÂChina Agreement concerning Kando as the Japanese ambassador to the Qing dynasty in Beijing.

Prime Minister Hara Takashi wanted Ijà «in to search for European institutions of public information when the latter was ambassador and a Versailles delegate. Ijà «in reported that the best way to create an influential information bureau was to coordinate all information sources, including army, navy and finance ministry. Eventually, a public information office, Gaimu-shà  Jà Âhà Â-bu, in the ministry of foreign affairs was established on 13 August 1921, and Ijà «in was appointed its head. Then he served as governor-general of Kwantung Leased Territory in northeastern China for one year. He was appointed to the post on 8 September 1922, replacing Isaburà  Yamagata.

Ijà «in was replaced by Keishirà  Matsui on 7 January 1924 when a new cabinet was formed by Kiyoura Keigo.
Ijà «in was married to à Âkubo Toshimichi's daughter, Yoshiko. Thus, he was the brother-in-law of Makino Nobuaki.
Shortly after his removal from the office, Ijà «in died of neuralgia in Tokyo in April 1924.
