Tokugawa Ieyasu is appointed Seiyo-tai shogun and establishes the shogunate in Edo.

IBAYA Kanzaemon moved to Edo (present-day Tokyo) when Ieyasu entered the Edo shogunate and engaged in pioneering work. He was given a gift of the land he had cultivated, so he settled in this area and began his business. The name of the store was taken from the village of Iba, with which it was associated.

At the time of its founding, the company dealt in Japanese paper and bamboo, and as an official merchant, it delivered materials and Japanese paper to the shogunate, which was also used for baskets and bamboo stools.
Washi was not made but purchased from paper-making regions such as Tosa and Awa, and bamboo was from Boshu.
