Tozama daimyō (外様大名, "outside daimyō") was a class of powerful magnates or daimyō (大名) considered to be outsiders by the ruler of Japan during the Edo period (江戸時代). Tozama daimyō were classified in the Tokugawa shogunate (江戸幕府) as daimyō who became hereditary vassals of the Tokugawa after the Battle of Sekigahara (関ヶ原の戦い). Tozama daimyō were discriminated against by the Tokugawa and opposed to the fudai daimyō, who were allies or vassals of Tokugawa before Sekigahara.

👉 Tozama in the context of Aizu domain
Aizu Domain (会津藩, Aizu-han) was a domain of the Tokugawa Shogunate of Japan during the Edo period from 1601 to 1871.
The Aizu Domain was based at Tsuruga Castle in Mutsu Province, the core of the modern city of Aizuwakamatsu, located in the Tōhoku region of the island of Honshu. The Aizu Domain was ruled for most of its existence by the shinpan daimyō of the Aizu-Matsudaira clan, a local cadet branch of the ruling Tokugawa clan, but was briefly ruled by the tozama daimyō of the Gamō and Katō clans. The Aizu Domain was assessed under the Kokudaka system with a peak value of 919,000 koku, but this was reduced to 230,000 koku. The Aizu Domain was dissolved in the abolition of the han system in 1871 by the Meiji government and its territory was absorbed into Fukushima Prefecture, covering much of the traditional region of Aizu.

The Uesugi clan (上杉氏, Uesugi-shi, historically also Uyesugi) is a Japanese samurai clan which was at its peak one of the most powerful during the Muromachi and Sengoku periods (14th to 17th centuries). At its height, the clan had three main branches: the Ōgigayatsu, Inukake, and Yamanouchi. Its most well-known member is the warlord Uesugi Kenshin (1530–1578).
