Completely self-taught, Sadahiro hasn’t read even a short manual. I asked if he takes inspiration from other designers, but he explained that for him, studying the work of others isn't really of great importance to him, “to hear the voice within more deeply, that is what influences me. Some of my customers make requests and they send me photos of other artist’s work and ask me to replicate into my own style. Truthfully, I don't always love these kinds of requests but since I work alone, the occasional request can be an unexpected stimulate to create something new.”
