Tenkara fishing was generally perceived in the 1950’s

Until then it was a hidden way of fishing

It could be that prior to the 1950s most people fished for food, and few primarily for recreation alone.
And from 1950s onward more people fished for recreation enjoyment. That rise lead to more people discovering & adopting Tenkara.

I wrote the kebari of that time on my web

Beautiful Kebari Flies. Thanks for the pics.
