IOGKF International hosted a black belt gasshuku at the Budokan in Naha, Okinawa, Japan, on December 3rd to 6th.  Forty black belt members from 13 countries trained six hours everyday.  Morio Higaonna Sensei (10th dan) taught all of the classes.  Every participant learned so much in detail and they appreciated the personal instruction they received from the world’s top martial artist.
