A taiko musuba (square knot), 2 part Nagoya type obi. Known as a tsukuri obi, tsuke obi or easy obi, with kanji design.
It says"Koto Shousen-ryu" in this obi. Koto is a very long, Japanese harp. The text on this obi is, I believe, the equivalent of an orchestra name or group name of a troupe of koto players.
Made and bought in Japan
Most obi, including two-part, pre-shaped taiko knot obi, require an obijime and obiage to hold the rear knot in place, both of which are always bought separately. With a taiko knot style obi, an obi makura (obi bustle pad) is worn inside the knot too, to pad it out at the top, though a few two-part taiko obis have a makura already inside the knot, however, most don't. One can buy actual obiage, obijime and makura or one can improvise with these items
Please be aware that different monitors display colour slightly differently. Therefore the colour in the photos and description is a guide only
