This is a high-end nagoya obi
made by Tatsumura Textile co., ltd, one of the most leading textile companies in Japan.
Woven partially with golden foil threads against the sleek red background, its pattern of milled seashells is unique but still full of elegance.
It seems to be designed from Rocaille style in 18th Rococo movement.
Textile is silk, and it's soft.
This seems unused with no folding line.
The stains on the backside are not disturbing.
There is an indication of stitches coming loose in the figure, but it's actually part of the design.
This piece doesn't have narrow belt part, but still short in length as Nagoya obi.
So, this piece can only make one-layered otaiko (square bow), but with its (wide) tare part double-layered, it can be tied in 'niju-daiko' (layered square bow), which is a more formal style.
Overall, it's still in very good condition.
For the details, please refer to the photos and the sheet.
