SATO™Triple Zoom 10’8”/ 11’10”/12’9” +Case The Tenkara USA Sato™ rod is named after Mr. Ernest Satow, an avid mountaineer who was the first person to make a written record of tenkara. The Sato is a compact and lightweight tenkara rod. At its shorter length it is perfect for tighter streams, and at its full length it will be ideal when the stream opens up again or when you find a bigger pool to cast your fly.
