Someone who is "Tenkara" master said, it may be fly fishing season when the wisteria bloom in mountain.
Actually there are many hatch mayfly and caddis and you may see also beetles in a mountain. It's now!
May 4. I went to quick fly fishing in a mountain stream and fished up several Yamame that is one of domestic trout in Japan.Every fish I caught on dryfly.
It's pretty beautiful season in mountain stream.
You should go to fly fishing, enjoy!
