Warrior Weekend is the annual Black Belt test for Chamberlain Studios.  Testing includes both Mudansha (colored belts) and Yudansha (graded ranks in Black Belt) levels in Gasan Ryu Kenpo.  The event is done largely outdoors at a facility that contains the elements of: reasonably priced housing, water access, open level ground, commercial kitchen space and indoor space for demonstrations and the promotion ceremony.

The dojo is closed for Warrior Weekend.
