My official Japanese art name

After 20 years of artistic career I have received my Japanese art name:  Toh-kou (東 虹) 

東 "Toh-" comes from 東雲 Tohun, the first part of my master's name

虹 has the meaning of a rainbow. Master Kobayashi, when he things about me, has an image of a rainbow that connects Europe and Japan. This title is a proof of my official following.
