The JKA (Japan Kendama Association) celebrated their 40th anniversary in 2015. The makers of the Shinfuji decided to release a very limited number of special edition kendama to celebrate. These special Rokurosen painted kendama have a Beech ken and Cherry tama.
While they are JKA certified they cannot be used for “Dan” level tests; only the lower level tests.
These are great additions to any kendama collection and a piece of history as well.
