[1] The domain and castle subsequently passed through a number of clans: the Aoyama from 1648-1662, the Sakai from 1662-1679, the Nishio from 1679–1682 and the Ishikawa clanfrom 1682–1702.

In 1702, a junior branch of the Makino clan was awarded Komoro, and remained in control until the end of the Edo period.

Following the Meiji Restoration, Komoro Castle was abandoned, and in 1871 with the abolition of the han system, most of its remaining structures were demolished or donated to nearby Buddhist temples and a merchant house.

The Shinano Railway Line cuts through the grounds of the castle, isolating the Ōtemon from the other remaining structures.

Also located within the former castle grounds is an amusement park, a zoo which opened in 1926, and a museum dedicated to Shimazaki Tōson.
