Located in Shin-Okubo—known as the “Town of Musical Instruments”—our shop is staffed by a repair team with proven technical expertise that has earned the trust of even the most uncompromising professional musicians.
While we all refer to it simply as “repair,” there are many different approaches. It’s nonsense to think that simply producing a sound is enough. It’s true that some repair shops do view the mere production of sound as their ultimate goal.
However, at Kubokan, our approach to wind instrument repair prioritizes one question above all else: “Is this the result the musician truly wants?”
Since an instrument is a tool, it is the mission of the Kubokan repair team to “adjust” it so that the musician can produce the sound they desire and play the music they envision.
Of course, this does not apply to used instruments.
At Kubokan, after we buy an instrument from a customer, we completely disassemble it to assess its condition. Since wind instruments accumulate rust and grime from moisture caused by the player’s breath, we use chemical cleaning agents to remove all dirt from the entire instrument, restoring it to a pristine state.
While a slightly stiff sliding mechanism can be temporarily fixed by applying oil, at Kubokan we certainly do not accept that as a solution. We carefully diagnose the issue—whether it stems from rust or dirt, a warped tube, or flaws in the design or assembly—and make the necessary adjustments.
The key to repairing used instruments is “how to restore the instrument to a neutral state.”
We strive to ensure that players can experience the instrument’s tone and character from a neutral perspective and make an informed choice.
While this may sound a bit formal, our staff members are very unique and, at the same time, very friendly.
Please feel free to consult with us about even the smallest details.
We’ll work with you to find the best solution.

What Is Kubokan’s “Wind Instrument Repair”?
Why Choose Okubo Gakki Musical Instrument Repairs?
The Peace of Mind That Comes from Seeing the Repair Work
The repair booth on the wind instrument floor is located in a corner of the sales area. Since all of our repair staff also serve as sales staff, we work right next to our customers—face-to-face—as they shop. There are no partitions or walls separating us. We don’t separate instrument adjustments and repairs from the instrument-selection process, allowing us to offer a wide range of suggestions in response to your inquiries.
Listening to Your Needs
Our repair staff will speak with you directly and propose repair methods tailored to your needs. If you have specific requests—such as “I’d like this part fixed this way”—please let us know.
If you’re thinking, “Something doesn’t feel quite right, but I’m not sure what to ask for,” we’ll perform a full inspection, focusing on the problematic areas. We’ll let you know which parts may need repairs in the future and what the current condition of your instrument is.
Please feel free to consult us even if you’ve been using your instrument for a long time without ever having it adjusted, or if you’d simply like us to assess its current condition.
Feel free to bring in vintage or rare instruments as well
For over 30 years, our shop has handled a wide variety of instruments, from historic masterpieces to the latest high-end models. We don’t just restore vintage instruments to a state where they produce sound; we strive to perform adjustments that upgrade them to be more functional while preserving their original character and atmosphere.
In addition, the most common service request for brass instruments is internal cleaning. Whether it’s an instrument you’ve played for years or one that’s been sitting unused for a long time, we’ll clean it to the same standard as the used and vintage instruments we sell.

Frequently Asked Questions
General Information on Wind Instrument Repair Services
Q. Can you repair wind instruments purchased at other stores?
A. Yes, of course. We’re happy to service instruments purchased elsewhere, regardless of the manufacturer or when they were purchased. Even if you’re unsure whether an older instrument can be repaired or want to assess the condition of an instrument you’ve inherited, please bring it in for a consultation. Our expert staff will carefully evaluate it for you.
Q. How much do wind instrument repairs cost, and how long do they take?
A. It depends on the condition of the instrument and the nature of the repair, but we can provide a free estimate in-store. For simple adjustments, we can usually return the instrument within a few days; however, if a full adjustment or overhaul is needed, we generally require the instrument for several weeks to a month. For detailed price estimates, please refer to the price list on this page or feel free to contact us via chat.
Q. Do I need an appointment for repairs?
A. Yes, we recommend making a reservation to ensure a smooth experience. We tend to get particularly busy on weekends and holidays. If you contact us in advance, we can set aside time for you to consult directly with our repair staff, allowing for a quick on-the-spot diagnosis and a prompt estimate. Even in the event of a sudden problem, please feel free to contact us first.
Woodwind Instrument Repairs (Saxophone, Flute, Clarinet)
Q. How often should I have my saxophone serviced (adjusted)?
A. We recommend regular adjustments for your saxophone about once every six months to once a year. This is because the saxophone has a complex structure, and the condition of the pads can change easily even when the instrument is not being played. Regular balance adjustments dramatically improve playability and help prevent major repairs.
Q. I dropped my clarinet and it cracked. Can it be repaired?
A. Yes, while “repairing cracks in the body” is one of the most technically demanding clarinet repairs, we are able to handle it at our shop. We’ll assess the condition of the crack and recommend the best course of action, such as gluing or pinning. We also specialize in restoring older instruments, so please consult with us before giving up on your instrument.
Q. My flute has become difficult to play. Is it broken?
A. The most common issues we see with flute repairs are “difficulty producing sound” and “keys that won’t move.” These are primarily caused by gaps in the pads or an imbalance in the mechanism. At our shop, we perform precise balance adjustments to restore the flute’s original delicate tone.
Brass Instrument Repairs (Trumpet, Trombone, French Horn)
Q. The pistons on my trumpet won’t move, or the slide won’t extend.
A. Please do not force it; simply bring it to our shop as is. For trumpet repairs, we use specialized tools to remove stuck slides and adjust pistons. Additionally, since dirt inside the tubing is often the cause, we also recommend a “tube cleaning” service using a specialized cleaning solution.
Q. The slide on my trombone isn’t moving smoothly. Can this be fixed with an adjustment?
A. Yes, it can be fixed. In trombone repair, slide adjustment is the most critical factor affecting playability. We correct any warping and remove dents from the slide to ensure smooth movement. We also repair dents caused by dropping the slide.
Q. Can you adjust the rotaries on my French horn or replace the strings?
A. Yes, we can. For French horn repairs, we frequently receive requests to address rotary valve malfunctions or broken/replacement strings. Cleaning and greasing the interior of the rotary valves, along with replacing the strings, will significantly improve playability.
Repairs for Large Instruments (Euphonium, Tuba)
Q. Can you repair dents on large instruments like euphoniums and tubas?
A. Yes, we do. Because euphoniums and tubas are large instruments, they are prone to being bumped, and we frequently receive requests to repair large dents in the bell or U-tube. We use specialized tools designed for large instruments to restore them as closely as possible to their original shape.
Q. Since I live far away, can I send a large instrument, such as a tuba, to your shop for repair?
A. Yes, we accept instruments for repair via shipping (shipping costs are the customer’s responsibility). Since instruments like tubas can be difficult to transport, many customers choose to ship them to us. To prevent damage during shipping, please contact us in advance if you have any concerns about how to pack your instrument.
