- Free fishing
- Fly only
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.
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.
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

Hokkaido is largely open-access for inland trout/char, with managed/charged zones the exception (e.g. the Akan C&R water). Verify the exact reach. Species surfaced in prose only. Legal status: guidance_not_permission.
