Yoko Nishina: Japanese calligraphy

Yoko Nishina likes to use black Japanese Sumi ink in her calligraphy work because of the variety of colours , from blues through to browns. Craftsmen still use traditional methods to create the ink from vegetable oil lamps with wicks made of reeds. She creates both large and small works - and is collaborating with photographer Kenro Izue for an exhibition in Osaka - as well as preparing a special exhibition for her upcoming 60th birthday, an age which is considered a "re-birth" in Japanese culture.
