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")^[16] – is the most-used obi type today. A Nagoya obi is distinguished by its structure: one end is folded and sewn in half, the other end is of full width.^[15] This is to make putting the obi on easier. A Nagoya obi can be partly or fully patterned. It is normally worn only in the taiko musubi style, and many Nagoya obi are designed so that they have patterns only in the part that will be most prominent in the knot. A Nagoya obi is shorter than other obi types, about 315 centimetres (10.33 ft) to 345 centimetres (11.32 ft) long, but of the same width, about 30 centimetres (12 in).^[18]
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.^[5]
The formality and fanciness of a Nagoya obi depends on its material, just as with other obi types. Since the Nagoya obi was originally used as everyday wear, it can never be part of a truly ceremonial outfit, but a Nagoya obi made from exquisite brocade can be accepted as semi-ceremonial wear.^[5]
The term Nagoya obi can also refer to another obi with the same name, used centuries ago. This Nagoya obi was cord-like.^[2]  - Wikipedia, 13/5/2020
