Japanese calligraphy was influenced by the Zen school of thought. For every sheet of paper, the calligrapher has but one chance to create with the brush.
The brush strokes cannot be corrected, and even a lack of confidence shows up in the work. It literally writes a statement about the calligrapher at a moment in time.
Taught by Nobuko Asada, a professor at the Japan Calligraphy Education Foundation.
