KubokanWhat is "wind instrument repair" at

Our store is located in Shin-Okubo, which is known as the town of musical instruments, and is supported by professional players who do not allow compromise.
There are various types of repair work. It is nonsense to say that just getting the sound out is enough. In fact, it is true that there are repair companies whose goal is to make sound.
HoweverKubokanWe at "The Wind Instrument Repair Company of Japan" think first and foremost, "Is that the answer that the player wants?
Because an instrument is a tool, it is important to "tune" it so that the player can produce the sound he/she wants to produce and the music he/she wants to play.KubokanThe mission of the repair team is to "adjust" the instrument so that the player can produce the sound and play the music he or she wants to play.

Of course, this does not apply to used instruments.
KubokanAfter purchasing an instrument from a customer, we disassemble the instrument and check its condition. Since rust and dirt accumulate on wind instruments due to moisture from blown-in breath, we clean the entire instrument with chemicals to remove all dirt and make the instrument flat.
The extraction pipe may be a little difficult to move, but it can be corrected by applying oil to it,KubokanBut of course, we do not allow that. We will determine whether the cause is rust and dirt, distortion of the tube, or poor design and assembly, and make adjustments.
What is required for the repair of a used instrument is "how to set the instrument in a neutral state.
We are conscious of this so that the player can feel the tone and character of the instrument from a flat perspective and choose the right instrument for him or her.
Our goal is to pass on a used instrument in perfect condition to the next player who needs it.Kubokanand it is our responsibility to make sure that the instrument is in perfect condition for the next player who needs it.

We have a very personal, yet friendly staff.

We will work with you to find the best solution.
