Can we make a complete list?
I think the Japanese Kendama Assoc. website might work for a start.
Start making up a list first and do a little research before asking people to do that for you.
Hmm… Can’t think of more…
Looks like a good start.
I’d like to note that only the OG Mugens are JKA approved. The newer 2013 Mugen Musous are not.
Kazuma Iwata supposedly had issues with JKA (regarding what, i have no info) in the past.
