This is an elegant Tsume-Tsuzure Fukuro obi
with Mt. Fuji and clouds pattern, which is woven on the dark background.
It also has tiny "HATSURIKOU" (small gap in the boundaries of colors), which is the distinctive feature of Tsume tsuzure
Textile is exquisite light silk. It is relatively soft Fukuro obi
Tsume-Tsuzure. It seems to be made in China.
It doesn't have a stiff lining inside.
There is a slight mold around the 'otaiko'(square bow) pattern.(*It was marked as a stain on the sheet. See the 1st photo of the flaw photos.)
There are some other flaws such as a slight folding line.
For the details, please refer to the photos and sheet.
If you don't mind those minor flaws, it is still in good condition to wear.
This must be an useful obi which you can coordinate with many kind of kimono to create different looks!
