Assumed European Dress.
The first thing he did was to have his topknot cut off, discard the Japanese dress and two swords, clothe himself in ordinary European costume and have his picture taken. He sent copies of the photographs home, and his family, friends, and official superiors were shocked at his apostasy. He knew that would be the effect, and to prepare himself for the storm that would greet him on returning he put in all his time studying European institutions, and in acquiring the rudiments of French and English.
When he arrived home in 1868 the revolution that ended forever the power of the Shogun, abolished the Samurai, and vastly curtailed the privileges of the nobility had begun. He remained true to the Shogun, but after the utter defeat of the latter before the walls of Kioto he entered the service of the Mikado, and his knowledge was of vast importance in the reorganization and rebuilding that came after the revolution had done its work.
In 1870 he was appointed assistant vice-minister of finance, and in that position he undertook to place the currency of the country on a firm basis. Japan was flooded with depreciated paper money, with a face value of so much rice. This was steadily called in and more stable money issued.
