White decorative parts are natural materials. ★Unauthorized reproduction of this instrument and unauthorized listing on eBay etc. have been confirmed. Currently, only this account is selling it. Please be aware. There are no breaks or damage, and it is fully functional and sounds good. However, as it is a used item, there may be minor scratches, so please check the images carefully. One of the wood grains on the soundboard has risen about 1mm due to aging, creating a step, but there are no problems with the sound or use. When listing, I strung it with new, high-quality biwa strings made by Kyoto Tobaya. On the video site Vimeo, I have uploaded a video of all position sound tests under the title Chikuzen502, so please take a look.
