Junzo Terada is a wonderful Japanese designer/illustrator. Sorry, I am too ignorant of Japanese to know Junzo’s gender! Comes Mart online sells a wide range of Junzo products including fabric, which is the 11th link down on the goods index. The interlocking animal designs remind me of Eleanor Grosch, only with a kawaii spin. Unfortunately Comes Mart does not ship internationally, but you can seek out a Japanese shopping service, like Shiratama Zenzai (blog).
The three prints above are fish — did you see that right away? It took me a minute.
Coordinating checks — there are more colors available too. What do you think of the faux aged/screenprinted look?
Superbuzzy has some border prints designed by Junzo Terada from the Bubu Pupu brand, and also some Tabi patches and twill tape. This was via Three Buttons, whom I have to thank today for sending me on this Junzo search!
