Ina clan

 was a Japanese samurai family which descended from Minamoto no Tsunemoto (894-961) of the Seiwa-Genji.
History.
The original surname of the family was "Arakawa", but the clan began calling itself "Ina" when it moved to the Ina region in Shinano Province in modern-day Nagano Prefecture. This move was ordered by the Ashikaga shogunate in the 15th century.
In 1590, Ina Tadatsugu was established in Musashi Province at Komoro Domain with 13,000 "koku" revenues. After the Battle of Sekigahara in 1600, the "han" was increased to 20,000 "koku". However, the clan was dispossessed in 1613 because of Ina Tadamasa's part in a plot organized by Okubo Nagayasu.
The clan were "hatamoto" until the Meiji period.
