Thank you for viewing. This is a honkan (main pipe) of a ryuteki, used in gagaku (Japanese imperial court music). I am not familiar with musical instruments, so I cannot provide a detailed explanation, but I was told by others that it is easy for women to handle and produces a beautiful sound. I received this as a gift, so I don't know its history before that, but it has been used for at least 40 years. Although there is some wear and tear, it has been carefully stored, so there are no major cracks or splits, and it is in relatively good condition for its age. However, it has hardly been used in recent years, and as shown in the last photo, there are faint, thin vertical cracks in two places between the finger holes. However, these do not affect the sound at all, and many people may not even notice them, so I will sell it as is. Please consider this only if you understand that it is a used instrument. Total length: Approximately 40.5cm Mouthpiece: Length approximately 2.0cm, Width approximately 1.5cm Thickness of the end of the pipe: 5mm End of the pipe: Inner diameter approximately 1.3cm, Outer diameter approximately 2.1cm Weight: Approximately 148g
