Japan Farmers Bet on Heat-Resistant Rice to Fight Climate Threat
Rising temperatures are hammering Japan's rice harvests. New heat-tolerant varieties like hinatamaru offer farmers a way forward.
Japanese rice farmers are increasingly turning to heat-resistant crop varieties as successive summers of scorching temperatures and drought conditions erode yields of traditional staples, according to reporting from Shiroishi, a rice-growing region grappling with the consequences of a warming climate.
Farmer Haruki Kawasaki, 63, is preparing to bring in this season's harvest of hinatamaru, a newer rice variety whose full, plump grains have held up through another punishing summer. The crop's resilience stands in contrast to the stress that conventional varieties typically suffer under high heat and reduced rainfall — conditions that have become increasingly routine across Japan's agricultural heartland.

The planting season in Shiroishi carried cultural as well as agricultural weight. Shinto priests performed blessing ceremonies when local schoolchildren helped sow seedlings in June, invoking deities for a productive harvest — a ritual that underscores how deeply rice cultivation is woven into Japanese rural identity even as the science behind the crop evolves.
The shift toward heat-tolerant varieties reflects a broader reckoning within Japanese agriculture, where climate change poses an existential challenge to the country's most symbolic staple food. Breeders and farming communities are racing to develop and adopt strains capable of withstanding the warmer future that climate projections indicate is already underway.
The experience in Shiroishi illustrates both the urgency of that adaptation and the cautious optimism that new agricultural science can offer communities determined to preserve a centuries-old crop. Continue reading at Business | The Guardian.
