Kaga Province
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.
