The article highlights Japan's efforts to develop plant-based and cultivated seafood alternatives to address the challenges of declining fish stocks and environmental sustainability. At a future food event, chef Takahiro Ota from Hotel New Otani presented children with a plate of sushi and sashimi made entirely from plant ingredients, primarily konjac-based "plant fish" developed by Azuma Foods. The development of such recipes is driven by concerns over declining fish catches due to environmental changes. Globally, fish consumption is on the rise, with the UN’s Food and Agriculture Organization reporting that seafood production reached 185.4 million tons in 2022, a 70% increase since the 1990s. However, Japan, once a fishing powerhouse, has seen a 70% decline in its fishery and aquaculture production since 1984, largely due to overfishing and being excluded from distant-water fisheries as countries established exclusive economic zones (EEZs). The once-abundant sardine stock has also dwindled due to overfishing. To address this, companies like Nippon Ham and Maruha Nichiro are investing in plant-based and cultured seafood. Nippon Ham developed plant-based tuna using konjac powder, recreating the texture and flavor of tuna after a year of development. This product is aimed at protecting fish stocks, particularly bluefin tuna, which is heavily restricted due to overfishing. Maruha Nichiro is working on lab-grown fish, though high costs—currently around ¥30,000 per 100 grams—remain a major hurdle. As fish prices rise, driven by poor catches of popular species like salmon and saury, plant-based fish may become more appealing. The consumer price index for fresh fish rose 50% over the past decade, outpacing the rise in meat prices. Companies are now exploring technological solutions to sustain Japan’s seafood culture while addressing global environmental and supply issues. #japan #seafood #ocean #fish #plantbased #food #trend #sdgs #sustainability
