Owari was initially ruled by
Fukushima Masanori with 240,000 koku until the
Battle of Sekigahara in September 1600. After his military achievements, he was reassigned to the
Hiroshima Domain. Matsudaira Tadayoshi, the fourth son of
Tokugawa Ieyasu, took control of the
Kiyosue Domain with 520,000 koku after Fukushima's departure. Tadayoshi died in 1607 without an heir, leading the territory to become Tenryo.
Tokugawa Yoshinao, Ieyasu's ninth son, arrived from the Kai-Kofu Domain with 472,344 koku and established a clan in Owari, expanding the domain over time. By 1619, the domain had grown to 563,206 koku, with an additional 50,000 koku added in 1671 to assert its position as one of the top three families. The total koku reached 619,500, encompassing territories in
Mino,
Mikawa,
Shinano,
Omi, and
Settsu. Despite officially having just under 620,000 koku, efforts to cultivate new fields led to an estimated actual koku of nearly 1 million, showcasing the domain's prosperity under Tokugawa Yoshinao's leadership. The first lord of the domain, Yoshinao Tokugawa, was still a child when he took office, so the early administration of the domain was carried out by Ieyasu's old retainers, but after he grew up, Yoshinao himself took charge of water supply, new rice field development, and annual taxes in order to increase rice production. He worked to establish the system and established the domain government.
Tokugawa Yoshinao, the initial ruler of the territory, took on the responsibilities of managing the water supply, developing new rice fields, and handling taxes to boost rice production and establish the domain's administrative structure.
Tokugawa Mitsutomo, the second lord, focused on policies related to temples and shrines, but excessive reconstruction led to financial instability. Fiscal reforms were implemented, but natural disasters further weakened the domain's finances.
Tokugawa Tsunamasa, the third lord, had a strong connection to the
Shogun through his mother, contributing to the expansion and diversification of the
Tokugawa clan's influence and power. After the restoration of imperial rule, oshikatsu played a crucial role in urging
Tokugawa Yoshinobu to resign. He aligned himself with the new government during the
Battle of Toba-Fushimi and actively suppressed the Sabaku faction during the
Aomatsuba Incident. Yoshikatsu Tokugawa, former feudal lord, was appointed leader of the Tokaido clans by the Meiji government after the Battle of Toba-Fushimi. He oversaw the
Tokaido fudai clans and sent envoys to neutralize Kokugaku groups to facilitate the passage of new government forces. In 1870,
Yoshikatsu absorbed the financially troubled
Takasu Domain to strengthen its stability. On July 14, 1871, the domain was abolished and transformed into
Nagoya Prefecture, which later merged with
Inuyama Prefecture to become
Aichi Prefecture. It further merged with
Nukata Prefecture to form present-day Aichi Prefecture. == List of daimyo ==
