This is a sioze pre-tied Nagoya obi
with fan motifs which are dyed.
Some parts of design are embroidered elegantly.
Textile is sioze silk, and it has soft and comfortable smooth touch which is the feature of sioze silk.
There are small stains (3rd photo) on tare end as the figure shows.
Upper otaiko part has prominent stains and color-staining (photo B).
Similar color-staining is seen on waist part, but not on wrong side. (It is actually on wrong side though written in black on the figure.)
There are smudges as well.
Please check photos and a figure for details.
It seems to be impossible to be tied.
