Yanagisawa is a Japanese saxophone manufacturer based in Tokyo, with roots tracing back to 1894 when Tokutaro Yanagisawa began repairing imported woodwinds for Japanese military bands. His son Takanobu built the company's first prototype saxophone in 1951, and Yanagisawa has since focused exclusively on the saxophone family, producing sopranino, soprano, alto, tenor, and baritone horns.

The brand is known for offering instruments in a wide variety of materials, including yellow brass, bronze, phosphor bronze, sterling silver, and solid gold. The 800 series (introduced in 1978) was the first to be exported under the Yanagisawa name, and later flagship lines include the 900/990 series and the WO series, with model designations such as the WO10, WO20, and WO37 across alto, tenor, soprano, and baritone variants. Yanagisawa also produces necks, mouthpieces, and accessories under sub-brands such as Yany SIXS and Yany BooStar.

Yanagisawa horns have a reputation among professional players for tight intonation, even response across the range, and a darker tonal character often contrasted with Selmer Paris and Yamaha. Players associated with the brand include Gary Bartz, Jay Beckenstein, Plas Johnson, Greg Osby, and Jess Gillam. In the United States, the line is distributed through Conn-Selmer.

Yanagisawa has 35 products cataloged on Equipboard, including Soprano Saxophones, Alto Saxophones, and Tenor Saxophones. Their gear is featured by 2 artists, with the strongest followings in Rock, Orchestra, and Blues. Notable users include Chris Potter and Atsushi Yanaka. Most Yanagisawa products sit firmly in the high-end, boutique range.
