Forestone is a Japanese woodwind manufacturer based in Osaka, best known for synthetic saxophone and clarinet reeds made from a proprietary blend of polymer and bamboo fibers. The flagship reed lines include the Traditional, White Bamboo, Hinoki, and Black Bamboo W-BLAST series, available in cuts and strengths for soprano, alto, tenor, and baritone saxophone as well as French and German system clarinets. The reeds are positioned as a long-lasting, consistent alternative to cane while aiming to preserve the warmth and response players expect from natural materials.

The company also produces professional saxophones in its GX, SX, and RX series, hand-assembled in Japan and finished with cryogenic treatment intended to free the metal's resonance. Rounding out the catalog are mouthpieces, necks, ligatures, straps, and reed cases. Forestone distributes through specialty woodwind dealers worldwide, with partner showrooms including TC Music in Taiwan and Musik Lenz in Austria.
