A very rare design, silk, Nagoya obi with a bare breasted geisha.
A Taiko-gara obi. Taiko-gara obis have a pattern only on the taiko (rear ‘knot’) part and centre front of the sash part. It's also called santsuu obi, which means “30% partially -patterned". The rest of the obi is plain. 
Made and bought in Japan
Type:
A Nagoya obi. Nagoya obis often have the sash part already folded to half depth, with the knot section at full width, making them easier to put on. Some you fold yourself. This style was invented about 100 years ago and is less heavy than a more formal fukuro or maru obi. Nagoya are usually tied in a taiko musubi (square style knot, named after the Taiko bridge, at the opening of which a few geisha wore it as a new style, after which it became very popular and has remained so ever since), though they can be tied in other knots. Nagoya obis are less formal than a fukuro or maru obis but more formal than hanhaba obis
