Botaori is a cotton textile from Kagawa prefecture that has been passed down since the Edo period. The name Botaori comes from the meaning “lasting many years” because of its durability. In plain weave, the warp and weft threads are crossed one by one; however, Botaori is done with three rows in plain weave, followed by the fourth row with floating thread. The gap created by floating the thread contains air, feeling smooth and cool in the summer and warm on the skin in the winter.
