Re: Yoshinkan in or near Boston?
There are no Yoshinkan schools in Boston at this time. Sounds like a great opportunity for your students to start one up. There is a school in Philadelphia and in New York. You might want to check out Utada Sensei's website and see if he has any affiliated dojo's in the Boston area.
Or maybe Mr. "RON" can chime in .....
There are many schools in the Boston area. Mostly Aikikai, not that that is a bad thing.
Good luck ...
