One of the things I like the most about Tenkara is the simplicity. Rod, line and a handful of flies is all you need.
Goertzen Adventure Equipment. They make two types; one with a fold out fly patch and one that will hold a standard Wheatley fly box (or similar sized box). This simple accessory holds all the flies you need for a day on the water, extra tippet, tools, and what ever else you feel the need to attach to it. I have two of these set ups. The one pictured above is set up for pursuing bluegills, the second one holds my traditional Tenkara flies.
