Fishing in Lake Kawaguchi

Do you need a permit?

A cooperative day permit is required. Typically ¥1,000–2,000. Day permit required. Renting a boat unguided requires a Japanese boating licence.

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 permitKawaguchiko Fishery Cooperative 河口湖漁業協同組合
  Its permit rules took effect 1 January 2024. Night fishing is prohibited on Lake Kawaguchi and wardens patrol. A separate local fishing tax applies on top of the permit.

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.
