Since ancient times, people in Japan have produced a form of ink known as sumi, which is used for calligraphy and traditional ink wash painting. Prepared in the form of ink sticks, sumi has to be diluted in water to create a black liquid. Until about 100 years ago, sumi was one of the most popular items sold at stationery stores. Today, ink sticks are rarely used in everyday life, but they are an essential aspect of traditional calligraphy. Shodo, the art of writing kanji characters with sumi ink, remains very popular. On this edition of Journeys in Japan, John Gathright travels to Suzuka, in Mie Prefecture, where sumi has been produced for centuries. He meets a traditional ink-stick master craftsman and discovers the vibrant art of calligraphy.
