He is a member of unico (Koriyama, Fukushima Prefecture). Tsuchiya's representative works can be broadly divided into a group of works titled "Leaves," which are shaped like skewers with dumplings on them, and a group of works titled "Flowers," in which the entire screen is painted in multiple colors. He also draws concrete objects such as "sushi," people, and sometimes takes notes on bus operations. Both "Leaves" and "Flowers" share the vivid colors that are common to both, and this, combined with the gentle image of plants, has made them popular with many enthusiasts. In recent years, he has also drawn sliding doors for newly built houses, and the walls of beauty salons and children's facilities, which have been well received.
