Most Yamaha YAS 23 alto saxophone does not have the “Made in Japan” engraved on the back, but this one does. It is in good working condition and it plays very well. It has been checked and serviced by a technician recently. This model is highly recommended by many band directors and teachers. I need to sell if because I decided to play the tenor saxophone. Contact by email. This is equivalent to the YAS-26 standard model ($2,166 new): $2,166 https://www.amazon.com/Yamaha-YAS-26-Standard-A...
