Hirado Domain

Hirado Domain (平戸藩, Hirado-han^?) was a Japanese domain of the Edo period. It is associated with Hizen Province in modern-day Saga Prefecture.

In the han system, Hirado was a political and economic abstraction based on periodic cadastral surveys and projected agricultural yields. In other words, the domain was defined in terms of kokudaka, not land area. This was different from the feudalism of the West.

After Toyotomi Hideyoshi’s successful conquest of Kyushu, local warlord Matsura Shigenobu was granted Hirado County and the Iki Island to be his domain. During the Japanese invasions of Korea, Hirado was a forward base of operations for Japanese forces. In 1599, Matsura Shigenobu erected a castle called Hinotake-jō on the site of the present-day Hirado Castle. However, he burned the castle down himself in 1613, as a gesture of loyalty towards Shōgun Tokugawa Ieyasu, having served in the losing Toyotomi side during the Battle of Sekigahara. In return, he was allowed to retain his position as daimyō of Hirado Domain under the Tokugawa bakufu.
