JKA Skill Levels

The Japanese Kendama Association have official skill levels. To qualify for any given grade, you have ten attempts to achieve each trick listed the required number of times. Example: to qualify as a grade 5 beginner, you have 10 attempts to hit Rousoku 3 times, another 10 attempts to hit Tomeken twice, and another ten attempts to hit Hikouki once. For grade 1, you also have two attempts to achieve 50 catches of Moshi kame.

All tricks at all levels must be performed with a JKA-approved kendama.
