Muramatsu Flutes is a flute manufacturer founded by Koichi Muramatsu. It is probably one of the oldest Japanese classical flute companies, having manufactured the instrument since 1923. Their handmade flutes are made from sterling silver; 9K, 14K, 18K, and 24K gold; as well as platinum. Many artisans who have worked for Muramatsu have also created many of the new companies in Japan that make high-quality handmade flutes.
