• saltwater-recreational — 居住者 No general national licence for shore-based recreational sea fishing. What binds you is the prefectural fisheries adjustment rule (都道府県漁業調整規則): permitted gear and methods, prohibited areas, closed periods, per-species size limits and restrictions on fishing under lights are all set there. Do not enter posted commercial fishing-rights areas (漁業権). Recreational bluefin tuna additionally requires a national notification — see the species rule., 非居住者 Same rules apply. Tourists fishing from a charter boat fish under the operator's arrangements, but the prefectural rules still bind the angler. The Fisheries Agency publishes a leaflet for foreign recreational fishers.
• freshwater-recreational — 居住者 Inland fishing requires a "yugyoken" (遊漁券) issued by the local fisheries cooperative for the specific river or lake, sold per-day or per-season at tackle shops and convenience stores near the water., 非居住者 Same yugyoken requirement applies to visitors.

FishRadar regulations are summaries for informational purposes only. Japanese recreational fishing rules are set at the prefectural level (都道府県漁業調整規則) and vary between neighbouring prefectures. Always verify with the prefecture and the local fisheries cooperative (漁業協同組合) before fishing, and never enter posted commercial fishing-rights zones. Bluefin tuna rules change during the season without notice — check the Fisheries Agency page on the day you fish.
