This Kuniyoshi woodblock print depicts Morozumi Masakiyo or Morozumi Torasada committing suicide. Masakiyo Morozumi was a famous General under Takeda Shingen. His death is chronicled in this woodblock titled as San Uchijini No Uchi or or One of the Three Heroic Deaths in Battle. Supposedly at the time Morozumi was in his eighties and had served three generations of the Takeda family in many different battles. This famous General was killed in the fourth battle between Takeda Shingen and Uesugi Kenshin. From what little I have found on this print, Morozumi committed suicide by thrusting his sword into his mouth just as a cannonball lands and kills him and all his followers.
