About Selling & Appraisals

What Kind of Store Is Okubo Gakki (“Kubokan”)?

From vintage pieces to the latest models, we’re packed with instruments you can’t try anywhere else but here!
Lately, we’ve been getting asked more and more often by customers, “So you handle used instruments, too?”
It’s true that our store is overflowing with New cases for wind instruments, and we carry the latest products from international brands like LOTUS TRUMPETS, AR RESONANCE, and GENEVA, so it’s only natural that people might get that impression.
However, our roots lie in the wind instrument division of a store specializing in used instruments. We are a long-established shop with over 35 years of experience, and we continue to focus our efforts on buying and selling used wind instruments to this day. That’s why you’ll find new models from international brands right alongside vintage pieces and budget-friendly used instruments. We carry a selection of instruments you won’t find anywhere else—instruments you can only get at our store.

Leave your case selection to “Kubokan”!

No other store can match our inventory of wind instrument cases. We confidently claim to be No. 1 in Japan. Our staff—true case enthusiasts—will help you find the case that perfectly suits your needs. If you’re having trouble choosing a case, please feel free to consult with us first.
Major Brands We Carry: GARD BAGS, Marcus Bonna, BRASS BAGS, PROTEC, BAGS, etc.

We’re passionate about mouthpieces!

We carry a wide selection of high-end international brass instrument mouthpieces, such as LOTUS TRUMPETS, AR RESONANCE, and PATRICK, as well as handmade saxophone mouthpieces crafted by Canadian artisan Sebastian Knox—all of which have been well-received by our customers. Furthermore, starting this year, we’ve begun selling used and vintage mouthpieces in earnest. We also accept trade-ins from customers. Stay tuned!

Why Choose Okubo Gakki?

“I wish this existed,” “I wish this could be done”


“I’m looking for this, but you don’t have it, do you?” “This kind of modification might be a bit too much…”
Leave it to us. Please consult “Kubokan” even for items you’ve never seen elsewhere, products you’ve been told are unavailable, or requests that have been turned down elsewhere. The requests of each and every customer are the driving force and energy behind Kubokan. We reflect these in our product lineup and tuning services, evolving every day.

Enriching Your Musical Life


Our relationship with you doesn’t end with the purchase of an instrument—that’s just the beginning. We also help with promoting live shows, recruiting band members, and other announcements. Whether you’re thinking, “I’m not really in the mood to play anymore,” or “The sound is a little different than I expected,” we’ll do our utmost to support you through any challenges or unexpected issues you may face after your purchase. In addition to long-term tuning guarantees and maintenance, please feel free to consult us about any detailed customizations or concerns you may have.

We’ll Take Full Responsibility


Our store specializes in used instruments. We receive purchase requests daily not only from within Japan but from all over the world.
“I haven’t been using it much lately,” “I wonder how much this instrument would sell for?” “I’m a little short on funds to upgrade my instrument”—everyone has their own reasons and timing for parting with an instrument. Please feel free to consult with us based on your specific circumstances.
We’ll restore the instruments you’ve cherished to the best possible condition and pass them on to their next owners. We buy not only current
models and popular instruments but also vintage pieces and instruments from lesser-known manufacturers. Feel free to contact us via LINE for a quick appraisal or by sending us a message.
