Narahara Kizaemon
Narahara Kizaemon was a Satsuma han retainer who is generally considered to have been the one most responsible for the death of English merchant Charles Richardson in the 1862 Namamugi Incident.
Some sources confuse him for his younger brother, Narahara Shigeru aka Narahara Kôgorô, another prominent Satsuma retainer.
