Season grading is our editorial judgement, not a sourced figure. It says when the fish is catchable, not when the water is legally open — for that, read the closed seasons below.

How far our answer goes here

  • ✓National lawApplies everywhere. Foreign-national gear limits, protected species, bluefin controls.
  • ✓PrefectureMinimum sizes, closed seasons and legal gear. This is a floor — local rules add to it, never subtract.
  • ~Sea-area / inland committeeDirectives that close specific waters or periods. We hold these for a few prefectures only.
  • —Cooperative permitSea fishing needs no cooperative permit. A Common Fishery Right still covers the shore — see the rule above.

Rules stack. Everything above the line we hold; everything below it you still need to confirm on the ground. That gap is exactly what a local guide is for.

Hiroshima pairs each size limit with a season rather than banning the size outright: undersized mullet, sea bass, rockfish, halfbeak and gizzard shad are protected only during the listed months. Hard clam and eel are the exceptions — those size limits run all year. The Seto Inland Sea Regulations apply on top, including the summer closure on small red seabream.
