Brother to the infamous Ito(h) Gekko(u), Tonyo's parents (Ito Shiko; mother, and Ito Tankyou; father) were also both professional potters, so pottery is in his blood. 
Although Tonyo initially made many of the pots that his brother painted, and is a fantastic potter in his own right, he never quite made the same accolade as his brother, who is one of the world's most revered painters of bonsai ceramics.

Tonyo's works tend to be small, but very precise and well built, with clean lines and superb detail and glazes. I have used a few for my mame and smaller shohin.
