Handing out sustainable seafood guides on the streets of Tokyo (c) Sutton-Hibbert/Greenpeace
There's a common comment in this part of the world, often repeated on the internet especially, about sorting out the seafood problem: namely, we have to change minds in Japan.
Whilst it's a simplistic generalisation, there is a lot of truth in that. Seafood is a global commodity and a global problem. The big markets for seafood are (perhaps unsurprisingly) North America, Europe, and Asia.
