Toyama Domain

Toyama Domain (富山藩^?, Toyama han) a feudal domain in Edo period Japan, located in Etchū Province (modern-day Toyama Prefecture), Japan. It was centered on Toyama Castle in what is now the city of Toyama. Throughout its history, it was ruled by a branch of the Maeda clan.

In 1639, the 3rd daimyō of Kaga Domain, Maeda Toshitsune, retired from office, and divided his domain among his three sons. Kaga Domain went to Maeda Mitsutaka; however, a 100,000 koku holding was created for his second son Maeda Toshitsugu (Toyama Domain), and a 70,000 koku holding for his third son Maeda Toshiharu (Daishōji Domain)

Initially, Toyama Domain consisted of several discontinuous areas: 60,000 koku in Nei District, 16,800 koku in Niikawa District (west bank of the Kurobe River, 3170 koku in seven villages around to town of Toyama and an exclave in Kaga Province of 20,000 koku in Nomi District. Although Maeda Toshitsugu moved into Toyama Castle in 1640, initially the castle itself remained part of Kaga Domain and he intended to construct a new castle in a different location within Nei District. However, he was unable to raise the funds for this endeavor and in 1659 reached an agreement with Kaga Domain to exchange the holdings in Niikawa District and the exclave in Kaga Province for Toyama Castle and the surrounding 27,000 koku of lands. In 1661, he received permission from the Tokugawa shogunate to rebuild the castle and to layout a new castle town.
