Kimono sash

OBI

This wide fabric belt is traditionally wrapped around a Japanese garment to secure it.

A kimono sash is the wide, decorative belt worn with a traditional Japanese kimono, and the Japanese word for it is "obi." The clue is straightforward with no wordplay—it directly names the item and expects the answer in its native term. Since "obi" is a common loanword in English, solvers familiar with Japanese culture or fashion will recognize it right away. If you’ve seen a kimono, the obi is the striking, often elaborately tied fabric wrapped around the waist.
