Nagoya obi (名古屋帯) – or to differentiate from the fukuro Nagoya obi, also called kyūsun Nagoya obi (九寸名古屋帯, "nine-inch nagoya obi").  A Nagoya obi is distinguished by its structure: one end is folded and sewn in half, the other end is of full width.  This is to make putting the obi on easier.  It is to be worn in the taiko musubi style, and this Nagoya obi has patterns only in the part that will be most prominent in the knot.  A Nagoya obi is shorter than other obi types.  The Nagoya obi is relatively new. It was developed by a seamstress living in Nagoya at the end of the 1920s. The new, easy-to-use obi gained popularity among Tokyo's geisha, from whom it then was adopted by fashionable city women for their everyday wear.

 Obi is a sash for traditional Japanese Kimono.

The obi for men's kimono is rather narrow, 10 centimeters (3.9 in) wide at most, but a woman's おformal obi can be 30 centimeters (12 in) wide and more than 4 meters (13 ft.) long.  The Obi itself does not keep the kimono closed; this is done by different under sashes (Koshi himo) worn underneath the obi. The obi itself often requires the use of stiffeners and ribbons for definition of shape and decoration.

There are many types of obi, most for women: wide obi made of brocade and narrower, simpler obi for everyday wear. The fanciest and most colorful obi are for young unmarried women and/or for weddings.   The contemporary women's obi is a very conspicuous accessory, sometimes even more so than the kimono robe itself. A fine formal obi might cost more than the rest of the entire outfit.

Obi are categorized by their design, formality, material, and use. Informal obi are narrower and shorter.
