Fishing in Lake Kasumigaura

Do you need a permit?

No permit is required. Legally treated as a sea area under the Fisheries Act, so the inland permit system does not apply.

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 permitLegally treated as a sea area under the Fisheries Act, so the inland permit system does not apply.

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.

Size limits and closed seasons

Not yet transcribed for this prefecture. The cooperative’s permit rules and national law still apply.
