6.Do you know "Endo Kinsuke"?
Born in Yamaguchi prefecture. He went abroad to study together with four far-sighted noblemen from Choshu (currently Yamaguchi prefecture) such as Inoue Kaoru (later Finance Minister) and Ito Hirobumi (later the first Prime Minister). He began to work for the Mint in 1870 and became the master of the Mint. He worked for the Mint for over 11 years, the second longest term of office among Mint masters. In 1883 his suggestion "Let's admire the beauty of cherry blossoms together with Osaka citizens" triggered the opening of "the Cherry Blossom Viewing through its tunnel".
