At present I'm under the impression that many if not most of our typical soft-hackled flies will work very well in tenkara water, using the fishing methods that best compliment the rods and set-ups. Not that it's as narrow as that. But there is a particularly active drift technique that can require forward facing hackles to resist current forces in order to achieve a pulsing impression of life. This I'll have to see for myself, but the tying of flies that are also distinctly tenkara-like is interesting and I would like to explore the facets involved.
Yes, these are fussier than the style apparently requires, but really...if you're going to sit down and tie a fly, why not put some thought into it and make it tidy? Did that extra 30 seconds really matter?
Here are a couple more from today. the first is tied tying off in front of the hackle

The second tied off behind the hackle. There is a larger tie off than I wanted but I need it to lock that hackle forward. I was trying to avoid adding a thorax.
