Сато Тадасу: Жапон дипломаты және саяхатшысы

Japanese diplomat (1850–1913)

was a Japanese career diplomat and cabinet minister of Meiji era Japan.

He was born Satō Shingoro in Sakura city, Shimōsa Province (present day Chiba prefecture), as the son of Satō Taizen, a physician practising "Dutch medicine" for the Sakura Domain. He sometimes referred to himself as "Satō Tosaburō". He was adopted as a child by Hayashi Dokai, a physician in the service of the Tokugawa shogunate, from whom he received the name Hayashi Tadasu. He learned English at the Hepburn Academy (the forerunner of Meiji Gakuin University) in Yokohama
From 1866 to 1868, Hayashi studied in Great Britain at University College School and King's College London as one of fourteen young Japanese students (including Kikuchi Dairoku) sent by the Tokugawa government on the advice of the then British foreign minister Edward Stanley, 15th Earl of Derby. Hayashi returned home in the midst of the Boshin War of the Meiji Restoration, and joined with Tokugawa loyalists led by Enomoto Takeaki, whom he accompanied to Hokkaidō with the remnants of the Shogunate Army and its Navy. He was captured by the Imperial forces after the final defeat of the Republic of Ezo at the Battle of Hakodate and imprisoned in Yokohama. Released in 1871 by Kanagawa governor Mutsu Munemitsu, he was recruited to work for the Meiji government in 1871, and because of his language abilities and previous overseas experience was selected to accompany the Iwakura Mission to Europe and the United States in 1871–1873. He returned home with the staff led by Henry Dyer as the principal, and endeavoured to set up the Imperial College of Engineering, Tokyo as an officer of the Engineering Institution of the Ministry of Public Works. In 1875 he married Gamo Misao (1858 – 1942). They had a daughter and a son, Kiku and Masanosuke.
