This item has been stored at home. Thank you for your interest. This is a 1.8-shaku, 7-hole, resin shakuhachi made by Mr. Minoru Muraoka, a famous figure in the world of modern shakuhachi. It is an old instrument, but it is in good condition with no cracks, chips, scratches, or stains. The inside of the utaguchi (mouthpiece) has been processed (though it's not visible), and the edge is thin and raised. Perhaps because of this, the high notes seem to resonate a bit more easily (this is just my impression; it probably depends on the player). The nakatsugi (joint) is firm and secure, with no worries about air leaks. It is recommended to use a lubricant like grease when inserting and removing the sections. When removing the sections, do not force them apart. Instead, hold the nakatsugi with one hand and gently tap the shakuhachi with your other hand from above to loosen the joint. Then, change the direction and repeat the process. While "Yu" is a well-known brand of resin shakuhachi, Muraoka tubes don't seem to appear very often on used instrument websites or flea market sites.
