Imai Sōkyū
Imai Sōkyū (今井 宗久, 1520 – 31 August 1593) was an important 16th century merchant in the Japanese port town of Sakai, and a master of the tea ceremony. His yagō was Naya.
A relative of the Amago and Sasaki samurai clans, Sōkyū originally came from Yamato Province. After settling in Sakai, he studied the tea ceremony under Takeno Jōō, eventually marrying Jōō's daughter and inheriting his teawares and lineage as a tea master. In his business, Sōkyū traded primarily in firearms and ammunition. Around 1554, after donating a large sum to the Daitoku-ji, he organized a shake-up in the local merchant circles by which he climbed into a position of considerable influence, and became a member of the city's leadership council.
He traveled to the capital in 1568, where he met with warlord Oda Nobunaga, and presented him with some tea accoutrements which had belonged to earlier masters. He thus earned Nobunaga's favor, and was granted a noble title. Shortly afterwards, when Nobunaga sought to lay claim to Sakai, many members of the council debated seeking defense from the Miyoshi clan, but Sōkyū was among those who suggested that the city submit. He acted as mediator to arrange the peaceful submission of the city, and was rewarded by Nobunaga with a lucrative commission to manufacture firearms for the Oda clan, and a post as a local magistrate. Sōkyū came to be responsible for tax collection in the outskirts of the city, and for pass-port applications and related matters. He was also assigned some jurisdiction over the nearby Tajima silver mine, and over the blacksmiths and metallurgists of the area, from whom he gathered materials to produce firearms and fireworks.
