ミサンガ

noun

misanga bracelet; friendship bracelet

A good luck charm made from knotted embroidery floss, thread, or gimp. Often tied around the wrist or ankle and worn until it falls off naturally, at which point a wish is said to come true. The word comes from Portuguese 'miçanga' (bead), but in Japanese it refers specifically to this knotted bracelet.
