F207. Kotsuka attributed to Joshin. 1.4 x 9.6 cm. Joshin was the 1st son of 2nd Goto master Sojo; he was born in 1512 and lived until 1562 (as well as being an artist and head of the most important family of kodogu makers, he was a bushi and died in battle at a relatively young age). As head of the goto family he worked for the 12th and 13th Ashikaga Shoguns, and other important people of his time. He, like the other early masters of pre-Momoyama time we refer to as Ko-Goto, took his name after entering the priesthood and did not sign his work. If you google Goto Joshin you will learn much more.
