Ōkuma Shigenobu
Kuroda Kiyotaka became the 2nd Prime Minister of Japan, after Itō Hirobumi in 1888. During his term, he oversaw the promulgation of the Meiji Constitution. However, the vexing issue of Japan's inability to secure revision of the unequal treaties created considerable controversy. After drafts of proposed revisions drawn up his foreign minister Ōkuma Shigenobu became public in 1889, Kuroda was forced to resign.
