Baron was an academic and politician of the Meiji period Japan.
Katà  was born on 5 August 1836, to a samurai family in Izushi domain, Tajima Province (present day Hyà Âgo Prefecture), and studied military science under Sakuma Shà Âzan and rangaku under Oki Nakamasu in Edo.
As an instructor at the Tokugawa bakufu's Bansho Shirabesho institute for researching Western science and technology from 1860 to 1868, he was one of the first Japanese to study German language and German philosophy.
After the Meiji Restoration, Katà  wrote numerous theses recommending Japanese adoption of Western forms of government, especially that of a constitutional monarchy with a national assembly based on representative democracy. He joined the Rikken Seiyà «kai political party, and was also a founding member of the Meirokusha intellectual society organized by Mori Arinori. A strong believer in social Darwinism, he drew parallels a democratic government and the natural order. As a member of the Genroin, he strongly supported Statism, a much more authoritarian version of government against the views propounded by the Freedom and People's Rights Movement.
Katà  gave lectures to the emperor each week on constitutional and international law, using translations from western texts to explain the concept of separation of powers between executive, legislative and judiciary branches of government, the history of constitutions in Europe, and various forms of local administration.
Katà  served as superintendent of the Departments of Law, Science, and Literature of Tokyo Imperial University 1877âÂÂ1886, and again as president 1890âÂÂ1893, and was head of the Imperial Academy 1905âÂÂ1909. He was also a special adviser to the Imperial Household Agency.
Katà  was appointed a member of the House of Peers in 1890, and was ennobled with the title of danshaku (baron) under the kazoku peerage system in 1900. In addition, he became a Privy Councilor.
He died on 9 February 1916.
