Hakata Domain

Hakata Domain (伯太藩, Hakata-han) was a feudal domain under the Tokugawa shogunate of Edo period Japan, located in Izumi Province in what is now the southern portion of modern-day Osaka Prefecture.

It was centered around the Hakata jin'ya which was located in what is now the city of Izumi and was controlled by the fudai daimyō Watanabe clan throughout all of its history.

Starting as a 3250 koku hatamoto in 1611, he serving in numerous posts within the administration of the Tokugawa shogunate, and by 1661 had amassed fiefs with an additional kokudaka 10,000 koku, mostly in Kawachi and Izumi Provinces, which elevated him to the ranks of the daimyō.

In 1698, Watanabe Mototsuna relocated his seat from Musashi to Izumi Province to better administrate the bulk of his holdings, and established a new jin'ya in what is now Minami-ku, Sakai.

The final daimyō of Hakata, Watanabe Akitsuna received the kazoku peerage title of Viscount in 1884.
