Distribution/Classification of Daimyo

Tokugawa Family 4.1 million koku

Liege Vassals 2.6

(2500) (So, in effect, 6.7 million for Tokugawa)

Fudai (or Vassal) Daimyo

(150)

6.3

Fudai daimyo (who prior to the Battle of Sekigahara had already been vassals of the Tokugawa), were the most trusted on Ieyasu's vassals, often referred to as his "Treaures among Men." A few fudai daimyo, such as the Ii of Hikone, held large han, but many were small so they depended on the prestige of their close affiliation with the Tokugawa for their status. The shogunate placed many fudai at strategic locations to guard the trade routes and the approaches to Edo. Also, many fudai daimyo took bureaucratic, official positions in the Edo shogunate, some rising to the position of roju or Senior Counselor.  By the late Edo period, ONLY members of fudai families had access to high-level bureaucratic appoints in the Bakufu government, a source of considerable annoyance to capable leaders from other han (domains) who felt that high-level positions should go to the most capable samurai regardless of their class status or regional origins.

Shimpan*(or Related) Daimyo

(21)

3.4

The shimpan were collaterals of Ieyasu, such as the Matsudaira, or descendants of Ieyasu other than in the main line of succession. Several shimpan, including the Tokugawa of Owari (Nagoya), Kii (Wakayama) and Mito, as well as the Matsudaira of Fukui and Aizu, held large han. See below.

Sub-Total 16.4 million koku

Tozama daimyo (who as a result of being on the losing side at the Battle of Sekigahara had agreed to submit to the rule of Tokugawa Ieyasu), were the least trusted, so-called "Outside Lords."The tozama daimyo held larger fiefs, with the Kaga han of Ishikawa Prefecture, headed by the Maeda clan, assessed at 1,000, 000 koku. Other famous tozama clans included the Mori of Choshu, the Shimazu of Satsuma, the Date of Sendai, the Uesugi of Yonezawa, and the Hachisuka of Awa.

Initially, the Tokugawa regarded them as potentially rebellious, but for most of the Edo period, marriages between the Tokugawa and the tozama, as well as control policies such as sankin kotai, resulted in peaceful relations.

Out of a total 25.8 million koku

The Tokugawa and their close allies control 16.4 million koku

*Three Large Shimpan Houses:

Mito 350,00 koku (North)

Owari (Nagoya) 619,000 koku (Central)
