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.

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.

Furuno Electric, headquartered in Nishinomiya, Japan, has grown from a small radio repair shop in postwar Nagasaki into the world's dominant marine electronics maker, holding 49% of the fishing vessel electronics market and 43% of commercial ship radar. From inventing the world's first practical fish finder in 1948 to today's AR navigation and autonomous vessel technology, discover how Furuno's "seeing the invisible" philosophy is shaping the future of seafaring. In 2024, their fish finder was recognized as an IEEE Milestone.

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.

Japan's abandoned bamboo forests have expanded to roughly 400,000 acres, causing landslides and destroying ecosystems. Taguchi Industrial from Okayama has answered with the "TakeKaruGon" - a domestically-made mulcher attachment for hydraulic excavators that shreds bamboo, large trees, and stumps in one machine. Discover how this innovation tackles one of Japan's most overlooked environmental crises.

A record-breaking 3,000 Steller sea lions have gathered on Benten Island off Hokkaido, Japan. Known as "sea gangsters," they cause roughly ¥1 billion (about $7 million) in annual fishery damage. While internationally protected as endangered, local fishermen face devastating economic losses. Explore this complex conflict between wildlife conservation and human livelihoods.

Japan's private rice imports reached 96,000 tons in 2025—95 times the previous year. Learn how historic domestic rice price surges made foreign rice cost-effective even with high tariffs, reshaping Japan's food security debate.

In 2025, Japanese agricultural corporation bankruptcies hit a record 103 cases. Learn about the structural challenges facing Japan's farming industry: weak yen, soaring material costs, labor shortages, and succession crisis, all while food self-sufficiency remains at just 38%.
