The speciality of the Takeda family compared with other clans was that they had an ample commercial network. The Takeda family had been outstanding at trade.
The headquarters of the Takeda-Family was located on a valley in a mountain district. They needed to make deals exchanging their own products of both land and sea through commerce. Salt was especially an indispensable product for the people of Kai living in the mountain range. Therefore, the trade route of salt in Kai had developed a lot. The Takeda-Family took advantage of such networks as much as possible.
Takeda Shingen, leader of the clan and daimyo of the Kai province, employed around 70 shinobi. He selected the top 30 candidates, took their wives and children under his custody, put them under oath, and entrusted them to each of three retainers. He then made up an organization of 200 shinobi by recruiting widely from monks, merchants, and samurai. They were called Mitsumono, and preformed espionage, deception, strategy, and counterespionage. Daimyos (大名) were terrified of the Takeda-clan because they had not only stolen information, but also committed arson, performed surprise raids, and even made hostile spies betray their lords.
