[1] The Revenge of the Soga Brothers incident occurred on June 28, 1193 during the grand hunting event Fuji no Makigari held by shogun Minamoto no Yoritomo.

The Soga brothers took their revenge and killed Kudō Suketsune on the last night of Fuji no Makigari.

The brothers began a bloodbath at the event, defeating ten samurai and slashing many others, during which Sukenari was killed by Nitta Tadatsune.

[4] This incident is recorded in the historical chronicle Azuma Kagami and the chronicle-tale Soga Monogatari, and its legacy lives on in the Sogamono plays in kabuki, noh, jōruri and kōwakamai theaters.

In 1563, Soga Harusuke served as Associate Governor (suke kokushi) of Kōzuke Province and Soga Saemon-no-jō (third officer of the Left Division of Outer Palace Guards) served as an infantry officer (ashigarushū).
