Troublesome procedures, knock-offs, incompetent staff, unexplained fees... Aren't you afraid of these things?

For example, going to a convenience store in the rain to get a copy of your ID is a hassle, and even if the purchase price is greatly reduced due to scratches or other defects, it is impossible without the knowledge to argue back, and if you ask for it back, you may be charged a fee.

I think it's natural to be anxious, especially if it's your first time making a request.

At TCGAKKI Group, you only need to read the QR code and enter the information on your smartphone to complete the process.
We have a wide and deep knowledge of our products, as you can see from the fact that the materials and articles we have accumulated in our 35-year history are still used as references by many music stores and recycle stores, and we are sometimes referred by other stores.
We do not charge any valuation fee, shipping fee, or business trip fee.
We have our own professional repair team, "TC-TUNE", which handles instruments of professional players, and we are able to offer high purchase price because the sound and performance of the instruments are revived by not only our repair and adjustment skills but also our observation and depth of suggestions, which results in increasing the value of the instruments.
We are able to offer you a higher purchase price than you can imagine, especially for used and vintage instruments of top brands.

If you think that there is no difference between the price of a used or vintage instrument and the price of a used or vintage instrument, or if you think that it is not worth the trouble of bringing it in or sending it to us, you may be better off with an online dealer.

We are a small group of people who share knowledge and skills, so we cannot respond to requests from all over the country at once.
Therefore, we give priority to those who contact us, and we share our feelings and history of the instrument with each of them before proceeding with the transaction.

Our role is not to dispose of the instrument, but to connect the history of the child.
Please contact us from the button above only if you think you can entrust us with your instrument.

If you are not sure where to entrust your purchase or whether you can get a really high price for it, please read this page and then decide slowly.

We understand that you may feel uncomfortable taking it to the store where you bought it.

Weunderstand that you may feel "it's hard to take it to the shop where you bought it "
but actually wedon't mind at all, in fact, weare very grateful because weknow the maintenance history andcan resell it easily!

Solid knowledge and understanding of vintage instruments

Because they are precious instruments, we will maintain them and securely connect them to the next person.

Since we purchase more than 800 items every month, the knowledge and experience of TCGAKKI's assessment staff is also very attractive!

When we come in contact with a large number of used instruments, we encounter a wide variety of instruments, from masterpieces and ultra-rare items to kiwimono, and we have a great many customers who come to our store because they say they don't recognize it at other stores.

And we are delighted to pass on the charm of old and tasteful instruments, instruments that have been carefully played, directly to the next owner. Our entire company is working together to promote the appeal of used musical instruments around the world!
