As an attempt to protect and promote craft techniques, the Japan Traditional Kōgei Exhibition has been held every year since 1954. This year, from September 20th to October 2nd 2017, the 64th edition is held at Mitsukoshi department store in Nihonbashi.
This exhibition is a rare chance to see some of the most skilled craftspeople’s work, from ceramics to lacquerware, dolls or textiles.
The display of ceramics is incredible and presents such a variety of techniques, I was in awe. On top of that, I was able to find out about some techniques I had never heard of before: washizome (和紙染め) and nunozome (布染め). Or, literally, printing with washi paper or cloth.
This painstaking process uses the absorbing quality of the washi paper to transfer the colour onto the ceramic piece. First, the pattern is drawn on the piece with a pencil. Then pieces of washi paper and delicately cut to the right shape. These pieces of paper are then put on the ceramic and the colour is added. The rough texture of the washi paper creates a unique effect while still allowing a high precision. You can see the whole process in this video.
Nunozome is a similar technique but allows for a variety of textures depending of the weaving pattern.:
“With nunozome fabrics are cut into shapes and placed on surfaces and transferred using a brush to bring out colors”
