This is a Shioze Nagoya obi
with fish, 'susuki'(Japanese silver grass) and 'Ume'(Plum blossoms) in circles pattern, which is dyed.
The fine gold glazing and embroidery works are applied on the pattern.
Textile is shioze silk with its characteristic soft and smooth texture.
The stains on 'otaiko'(square bow) could be hidden when you tie it.
Although it's not mentioned on the sheet and photo, there is a stain on 'maegara' (front pattern on belly) which can be hidden when you tie it.
There are some other flaws such as folding lines.
For the details, please refer to the photos and figure.
It has slight musty smell.
Enjoy wearing it as everyday clothes.
