The plan
Plan A
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water
Lake Chūzenji lies high above Nikkō, dammed by an old lava flow from Mount Nantai, and it carries a curious history: brown trout brought in by foreign residents more than a century ago, which took hold and grow large in the cold mountain water. A place of shrines, waterfalls and autumn maples, and a rare Japanese lake where the brown trout is the prize.
Under the surface
A high volcanic lake above Nikkō, formed when Nantai's lava dammed the valley — cold, deep and steeped in temple history. Brown trout introduced by early foreign residents thrive alongside char and kokanee, against a backdrop of shrines, falls and turning maples.
