Hikone Domain

The Hikone Domain (彦根藩, Hikone Han) was a feudal domain of Japan during the Edo period. It was established in 1600 with Ii Naomasa as the first daimyo. All fifteen daimyo were from the Ii clan.

A large fudai domain, Hikone was initially rated at 180,000 koku. The rating reached a peak of 300,000 (with the status of a 350,000 koku domain), and in 1871, when the domain was abolished, it was 200,000 koku.

The domain initially had its headquarters at Sawayama, the castle that had been occupied by Ishida Mitsunari prior to the Battle of Sekigahara. Construction of the new castle at Hikone began in 1603.
