This is a Nagoya obi
with 'natsume'(Jujube-shaped tea case) bag and transverse flute on 'Michinaga-dori'(wavy line) pattern, which is woven and embroidered.
It was produced by Juraku, one of the most famous Nishijin obi weavers.
Textile is relatively thick and smooth polyester and jinken (rayon) blend.
There is a large and noticeable stain on 'maegara' (front pattern on belly).
There are patinas(refer to the 1st flaws photo) and a
stain(refer to the 2ndt flaws photo).
For the details, please refer to the photos and figure.
Unfortunately, it maybe no longer in wearable condition due to the large stain.
It must be a good handcraft material.
