Across the year

The best month at any of the 3 places we have checked. Each place has its own window, and the season elsewhere in Japan may differ.

Where we have checked it

These are examples, not a complete list. Mahi-mahi is caught far more widely in Japan than the 3 waters below. We list a place only once we have worked out which rules apply there, so the absence of a water means we have not checked it — not that the fish is missing.
