This is a bag for storing the koto (Japanese harp). I, the koto player, handmade this. It's a bag for a 13-string koto, made using unused or repurposed fabric. It can also be used in place of a "yutan" (a protective cloth). It's designed to fit a koto that is approximately 185cm long. When going to a koto performance, transporting the koto can be difficult. When carrying the koto, you usually wrap it in a "maru-bukuro" (round bag) and then put it in a soft case. However, doesn't wrapping the koto in a "maru-bukuro" feel a bit cumbersome because it takes up a lot of space? So, I created a 13-string "koto bag" to make it easier to wrap and transport the koto. You can put the koto directly into the "koto bag," then cover it with your usual "yutan" and put it in a soft case. This can save time, especially since there are often many people and instruments at performances. The "koto bag" can be folded in a few seconds. The "koto bag" is made of silk or other materials. Since it is basically made from repurposed fabric, please understand that the fabric may not be perfectly clean. There may be some slight odors or yellowing, but the smell should dissipate with use. Therefore, I would like to offer it at a lower price. [This is a handmade item, so there may be some imperfections such as distortions or misalignments. The color may look slightly different from the actual product.] This is for those who understand and appreciate handmade items. Thank you. It will be folded, placed in a plastic bag for waterproofing, and then shipped. (The shipping method may vary depending on the thickness of the koto bag) "How to put the koto in the bag" 1. Lean the koto against a wall, etc., and insert it from the ryubi (tail end). 2. Place the koto on the floor. The player kneels on one knee on the floor. Place the koto on that knee and insert it from the ryubi. The ryubi should be near the knee. I think this is safer. 3. Using a standing playing stand. etc. Please perform the procedure in a safe manner. *The koto is not included.
