Aikikai USAF East Coast style (under Yamada Sensei's side):
Off the street = White Belt
5th and 4th Kyu = Blue Belt
3rd - 1st Kyu = Brown Belt
1st Kyu = Hakama (the downside of gaining the rank
)
Shodan-Judan = Black Belt and Hakama (Or in casual practice white belt and no Hakama because you forgot your Black belt at home and are having a bad day and don't want to fool around with Hakama, and no one out ranking you is around to point it out
)
