Ōkuma Shigenobu
In 1889, the "Gen'yōsha" strongly criticized the unequal treaty revision plan drafted by foreign minister Ōkuma Shigenobu. A Gen'yōsha member threw a bomb which wounded him severely. In the election of 1892, the "Gen'yōsha" mounted a campaign of intimidation and violence with the tacit support of the Matsukata administration to influence the outcome of the election.
