These are the strings or chains, attached to loops on the inside of the haori collar at lower chest level, to keep the haori closed and stop it flapping too much. I have only just started to add loops to my haoris, because I was mostly making them as casual jackets that were meant to be worn open. But I love the variety and humour that can be seen in the different types and styles of himo.
As you can see from this photograph, sometimes the haori himo are as simple as to woven flat strings with the threads gathered into tassels at the end. But sometimes you see the most wonderful metal chain haori-himos that incorporate semi-precious stone beads.
They remind me of the beautiful hat strings worn by the Korean aristocracy during the Joseon period.
