The Tokushima Domain (徳島藩 Tokushima-han) was a Japanese domain of the Edo period, located in Awa Province and Awaji Province in Shikoku. Ruled by the Hachisuka family, it was rated at an income of 256,000 koku. Uncharacteristically for most domains of the Edo period, the Hachisuka were in control of Tokushima before the start of the period and remained in possession of it through the period's end.
In the early Meiji era, there was a major source of conflict within the domain, as the retainers of Inada Kurobei, Lord Hachisuka's senior councilor and warden of Sumoto Castle, demanded independence for their lord and his establishment as a daimyo. With Inada's income already over 10,000 koku, this was technically possible; however, it was refused, and met with violent opposition from Tokushima. After the "revolt" was put down, the entire Inada clan and its retainers were exiled to the far northern tip of Hokkaido. Their experiences are fictionalized in the recent film Kita no Zeronen ("Year One in the North").
