'' reported that Japan's first diplomatic mission to the West received the news about what had happened in Edo. The assassination dealt a severe blow to the prestige of the Shogunate so that officials refused to admit Naosuke's death for a month, claiming that he was merely injured and was recuperating. The minister's death was only made official in April when the office of Tairo was declared vacant.


Fate and punishment of Ii Naosuke’s entourage

Out of the 60 samurai guards defending Ii Naosuke, 4 died in combat and 4 died within days from fatal wounds. Those who were killed in action were allowed to keep and pass-on their hereditary samurai names and status to their heirs. Survivors, however, all received various degree of punishment for failing to protect the Chief Minister. Two years after the incident in 1862, investigation was completed and verdicts were reached to punish the surviving guards. The seriously wounded, such as Shugoro Kusakari, were exiled to the Sano,
