Gunsen (Folding War Fan)

A light one is recommended. You can carry it at your waist or hang it to the ring on the chigakushi (upper part of the breastplate), or fasten it to the cords of the hikiawase (the opening point of the body armour), but when in actual fighting do not hang it on the chest as it is then very inconvenient in using the sword or bow and arrow.

Garbutt adds: These fans have the outer sticks usually of iron, the inner ones often of yellow metal.
