On September 6, 1859, Hotta resigned his posts in favor of his son, and went into official retirement. He continued to lend his political support to the Hitotsubashi faction which was opposed to Ii Naosuke, and during the Ansei purge of Hitotsubashi partisans, he was placed under house arrest within Sakura Castle, where he died on March 31, 1864 at the age of 55.
