The fukuro obi is a type of traditional Japanese sash worn with a kimono. It is characterized by its wide, flat design and is often made from luxurious fabrics, featuring intricate patterns and colors. The fukuro obi is typically worn by women for formal occasions, such as weddings and tea ceremonies, and is tied at the back in a decorative knot. Unlike other obi styles, the fukuro obi is usually a single piece of fabric that is folded over, giving it a more elegant appearance. It is often paired with a haneri, a decorative collar, and can be complemented by various obi accessories to enhance the overall look of the kimono ensemble.
