Kuroda Kan'ichi

was a self-taught Japanese political philosopher and social theorist, associated with Trotskyism, who was deeply involved in far-left political movements. Nearly blind, In particular, Kuroda criticised the mechanical "materialism" that was prevalent in the orthodox Marxism, and instead developed a philosophical theory of "Materialist Subjectivity".

In 1959, Kuroda Kan'ichi was expelled from Kakukyōdō in the wake of a scandal in which he tried to sell compromising information about the JCP to the Tokyo Metropolitan Police Department (MPD). Thereafter, Kuroda, along with his right-hand man Nobuyoshi Honda, founded their own, splinter group of Kakukyōdō, with the appellation "National Committee" added to the name, and took many of their followers with them to create the "Japan Revolutionary Communist League National Committee".

Kuroda's branch of Kakukyōdō rapidly gained influence in the nationwide student federation Zengakuren, as many left-leaning students flocked to Kuroda's teachings.

However in 1963, Kuroda's branch of Kakukyōdō itself splintered as the result of disagreements between Kuroda and Honda over whether to pursue socialist revolution in alliance with others, or to focus on strengthening and expanding a single revolutionary organization, with the resultant split of the organization into a "Central Core Faction" (Chūkaku-ha), which was led by Honda and favored allying with others, and the "Revolutionary Marxist Faction" (abbreviated Kakumaru-ha), which staunchly adhered to Kuroda’s insistence on going it alone.

Under Kuroda's guidance, Kakumaru-ha participated in a number of protest movements in the later 1960s and 1970s, including the 1968-69 Japanese university protests, the 1970 Anpo protests, and the Sanrizuka Struggle against the construction of Narita Airport. It also engaged in violent conflict with Kuroda's erstwhile comrade and arch-rival Honda's Chūkaku-ha. By the mid-1970s, this conflict was resulting in several deaths per year16 in 1975 alone, including Kakumaru-ha's assassination of Honda himself.

Later life and death

Kuroda continued to lead Kakumaru-ha into the 1990s, when he retired due to ill-health. In 2006, he died of liver failure at the age of 78.
