See link to Lancashire Aikikai/Hombu grading system  https://www.lancashireaikikai.org/technical/grading.html

There are no coloured belts in traditional Aikido

Gradings start at 6th Kyu and progress to 1st Kyu, all with a white belt

Dan grades then start from 1st Dan (Shodan) and progress upwards from there

The black flowing over-trousers are known as Hakama and is a discretional award, which relates to teaching status rather than a specific grade. Wearing of Hakama tends to be awarded somewhere between 1st Kyu and 1st Dan

All Aikido Wexford grades up to 2nd Kyu will be awarded by Chris Wallace Sensei, your local instructor. 1st Kyu gradings will be administered by the LA Grading Review Group (GRG).

To progress to Dan Grade, it is a general requirement to attend courses with Mimuro Sensei when he visits the UK, so he can monitor progression

Dan Grades will generally be awarded by Mimuro Sensei
