F flute made of female bamboo from Keena Kobo Pino in Sayama City, Saitama Prefecture. Features of Pino Keena: A technique that no other Japanese keena maker has mastered, the bamboo is baked all the way through. This was specially taught by a craftsman at a keena workshop in Peru. By baking the bamboo inside, the pitch is less likely to change even after many years, and it becomes a durable keena that is resistant to cracking and insect damage.
