High Treason Incident

Maruki Gallery for the Hiroshima Panels


Iri Maruki, Toshi Maruki
On January 18, 1911, Shusui Kotoku and 24 others were sentenced to death on the grounds that they had conspired to assassinate Emperor Meiji. This case, known as the “Taigyaku Incident” or “Kotoku Incident,” ended a week later on January 24 with the execution of 11 people, including Kotoku Shusui, Oishi Seinosuke, Uchiyama Gudo, and others, and the following day on January 25 with the execution of Suga Kanno.

In 1989, along with a series of works on the Ashio Mine Poisoning Incident, Iri Maruki and Toshi Maruki collaborated on “High Treason Incident,” which they had been thinking they had to depict somehow for a long time. Shusui Kotoku is known as a great writer, and when Shozo Tanaka appealed directly to the Emperor Meiji about the Ashio mine poisoning, he drafted the letter of appeal. The fact that the “Taigyaku Incident” was depicted in connection with the “Illustration of the Ashio Mining Poisoning” seems to be due to this association.

This year marks the 110th anniversary of the Taigyaku Incident and the 150th anniversary of the birth of Kotoku Shusui. As Iri Itsuri said, the incident in which people who spoke out against social inequality and irrationality were eliminated is the starting point of history when considering modern society. This is the first time in four years that “High Treason Incident” has been shown to the public.
