Aquaponics rarely pays as a standalone farm. So how does Aomori's closed-school project plan to make money? By monetizing the cafe, tours, education and welfare work around the tank, backed by public funds.
Anglers curse it, and it devours kelp forests. Now a patent-pending method to kill the rabbitfish's notorious stench has Japan talking. A look at turning a nuisance fish into food, and how the world is doing the same.
In 2002, Japan's Kindai University pulled off the world's first full-cycle bluefin tuna farming. Two decades on, the major seafood companies are walking away and commercial output is fading. The irony: the headwind is the recovery of wild tuna stocks. A look at the gap between sustainable and profitable.
With water that is neither sea nor fresh, Okayama University of Science is trying to farm salmon through its entire life cycle on land. If it works, the university calls it a world first. We unpack the technology behind it, why salmon is the hardest fish to farm this way, a 250-year-old salmon town's role, and the global scramble for farmed salmon.
Tokai University is chasing a world-first: land-based, full-cycle aquaculture of the common octopus, long considered one of the hardest animals to farm. We unpack the cannibalism and escape problems, the clever 'octopus apartment,' the global octopus shortage behind it, and the ethical fight that has already produced farming bans abroad.
Kumamoto University has built a world-first device that kills anisakis parasites in raw fish using a 30,000-volt pulse lasting one-millionth of a second, without freezing or cooking. A look at the food-safety tech behind Japan's sashimi culture.
Japan's Fisheries Agency will sell fully farmed eel to the public for the first time on May 29. After cutting glass-eel production cost from 40,000 to 1,800 yen, the country aims to end wild-juvenile dependence by 2050.
Caviar's definition of 'best' has shifted from geography to aquaculture technology. As China supplies 60% of the world's farmed caviar and Russian product disappears under sanctions, a landlocked Japanese prefecture is challenging the global hierarchy with a hybrid land-based farming system that combines patented closed-loop tech with rare ultra-soft spring water.
Japanese telecom giant NTT runs a land-based shrimp farm in Iwata, producing 180 tons/year and capturing the largest domestic share. A deep dive into the 10-year plan to free Japan from its 90% shrimp import dependence, plus how it stacks up against Norway and Singapore.
On April 23, PM Sanae Takaichi met five foodtech CEOs at the PM's Office: Oishii Farm, PlantX, FRD Japan, Regional Fish, and Toko Tekko. Why these five? This article decodes how each company's technology answers one of the world's four shared food crises—climate-driven farmland collapse, ocean depletion, population growth, and shrinking farmer populations—and the strategic logic behind Japan choosing to win in specific categories rather than competing across the board.
Once dismissed overseas as resembling 'black paper,' nori is now riding the global onigiri boom into kitchens worldwide. A 3-Michelin-star Italian chef uses nori pesto on cuttlefish, and the global market is projected to grow from $3.8B in 2025 to $6.4B by 2034. From the famous 2010 Nature paper that overturned the 'Westerners can't digest seaweed' myth, to Japan being overtaken by Korea in production volume — here's how Japanese seaweed conquered the world.
Food tech is one of 17 pillars in Japan's new national growth strategy under the Takaichi administration, with a 30% global market share target by 2040. Beyond the obvious giants like Maruha Nichiro, Nissin, and Kikkoman, this deep dive spotlights 5 lesser-known but high-potential players: Regional Fish (gene-edited seafood), FRD Japan (closed-loop salmon), Chitose Bio Evolution (algae unicorn), UMITRON (aquaculture AI), and Oishii Farm (NY strawberry factory).
Japan's agriculture ministry hosted ambassadors from 60 countries to showcase cutting-edge food technology including vertical plant factories and land-based aquaculture. With food tech designated as one of 17 national growth strategy sectors under the Takaichi administration, Japan targets 30% global market share by 2040. Covers key startups like PlantX, full-cycle aquaculture, and alternative protein trends.
Japan's largest seafood company Maruha Nichiro has partnered with Singapore's UMAMI Bioworks to develop cell-cultivated bluefin tuna using cells from fully farmed fish. Targeting overseas sales by FY2027, this report covers the technical breakthroughs, commercialization challenges, and global cultivated meat market landscape behind Japan's ambitious quest to produce fish without the ocean.
For 6,000 years, Japan has eaten fugu — a pufferfish carrying tetrodotoxin, a poison 25 times deadlier than cyanide with no known antidote. From warlord bans to a prime minister's secret feast, from a Living National Treasure's fatal last meal to chefs who train for years to earn their license, this is the story of how Japan turned the world's most dangerous fish into high art. Does your country have a food worth risking your life for?
The Chinese vessel seized in Japan's EEZ used a "tiger net" — a devastating method with 1cm mesh that strips the ocean bare, including juvenile fish. Explore how this "sea vacuum cleaner" works and why IUU fishing by Chinese fleets threatens oceans from South America to Africa.
Up to 90% of farmed oysters have died in parts of Hiroshima Prefecture, Japan's largest oyster-producing region responsible for 60% of national output. Rising water temperatures, high salinity, and oxygen depletion in the Seto Inland Sea have caused unprecedented damage to a 450-year-old aquaculture tradition. We report on the causes, impact, and what comes next.
Japan's Fisheries Agency seized a Chinese fishing vessel and arrested its captain in the EEZ off Goto Islands, Nagasaki, on February 12, 2026—the first Chinese vessel seizure since 2022. We report on illegal fishing in Japanese waters and Sino-Japanese maritime tensions, with reactions from Japan and abroad.
Kindai University has achieved the world's first full-cycle aquaculture of Nodoguro (Blackthroat seaperch), a high-end deep-sea fish known as the "White Toro." Learn about the decade-long journey, the technical challenges overcome, and what Japan's aquaculture leadership means for global food security.
Japanese aquaculture breakthrough enables female eel production through patented technology. "Enman" offers richer flavor and texture, emerging as a premium delicacy. Explore how Japan is revolutionizing traditional eel farming.
