This yellow woven, synthetic satin fabric obi is an example of a han-haba obi or half-width obi, a more informal sash that is worn casually with summer yukata. This obi is sewn over a stiff lining. The han-haba obi is very popular in Japan these days, since tying is relatively easy and it can be folded and twisted in many different ways.
An obi is a sash for traditional Japanese dress and comprises a major part of kimono outfits. There are many types of obi, some of which are wide and made of brocade and others that are narrower and simpler for everyday wear. In formal Japanese dress, obi are tied in elaborate and decorative ways.
