In Wada's garden there was acanthus. Although it is a southern plant, it is quite resistant to cold and remains green until the latest in the winter garden when everything is dead-colored. The brightness of its leaves is suggestive of the southern sun, which is why Wada uses the Kanji character for "taiyou-mon" (泰葉文). The Japanese word for sun is pronounced taiyou (太陽), and taiyou (泰葉) have the same sound.The word "葉" indicates a thin state, and especially when a thin object such as a pattern is attached to a form, its power expands and changes the world of the form. This work brings a richness of change and freedom.
