imoo I think that if you want to take classes, you should check to see how close this person is linked to japan. I know what your going through i my self have run in to a problem where i couldnt link a certain instructor to japan for that matter instructors that i had contacted never heard of this guys org. if you qustion your instructors abilities contact other instructors to find out if they know that inpaticular organization. You do have to be carefull because there are a lot of foney orgs, that are selling ranks for top dollar.
Thanks for listening.
