I just know someone is going to ask...........
freshwater or ocean fishing. Flyfishing or trolling or deepwater? With a guide or without? Probably better ask about licenses and cost and where a foreigner can go to fish. Boy , when you think about something as simple as fishing , there sure are a lot of details to think about. I wonder if you could have what you catch shipped home? I wonder if you could get a trophy fish mounted and shipped home? How about , can you bring your own fishing gear from the states into Japan?
I wonder if we have any fishing experts here who can answer these type questions?
