Who can tell me how Toshiichi Kubo, one of Japan's three great reformers, died?

Meiji 1 14 At 8 o'clock on May, after welcoming the Shan Zhi Festival in Fukushima Prefecture, he drove to Taisho Office and was assassinated by gentry of civil rights groups such as Teru Shimada Ichiro in Ishikawa Prefecture, and then fell to the ground and died.

In fact, the main reason should still be Okubo's suppression of civil rights groups in the Southwest War, and some former governors did not get the desired status.
