All kinds of water from urban ponds to big rivers.
I have just about every rod TenkaraUSA makes and it has become perhaps y favorite way to fish, but the Hane adds a whole lot of other dimensions and in otherwise tough circumstances for the longer rods. It works like a dream in so many ways, small creeks, overgrown areas, Euro style ( and especially with a dry and dropper type set up), windy days and more.
If I were to press for a drawback, it would be the fragility of the tip section, but that is a big part of what I like about it, the sensitivity that comes with the fragility. And what Tenkara rod doesn't have a somewhat fragile tip?
I had problems with breaking tips when I first started fishing Tenkara, a lot my own fault for not studying more as to what's available on the web site and then "practicing it." Replacement tip sections are eminently and reasonably priced, if not sometimes free. I learned a lot also by calling the company (emphasis on "breaking down" the rod a bit after landing a bigger fish, keeping things very straight when handling and so much more. It's quite special when the founder (Daniel) answers the phone and seems willing to talk and share all day.
Being a bit facetious, I cannot say the Hane is the best of the lot because all the models I have are 5 stars or more in my book. Not only is Tenkara incredibly effective, engaging and fun, but there is something about the simple elegance of it that moves me greatly. It takes some time and effort to get to feeling competent and having a sense of what to do and where, but it sure is worth it.
