TOKYO –
Japan’s Fire and Disaster Management Agency said Monday that two weeks of harsh winter weather have left 27 people dead in snow-related accidents nationwide and 290 others injured, with Niigata Prefecture on the Sea of Japan coast the hardest hit. (nippon.com)
Snowbelt toll concentrates on Sea of Japan prefectures
The victims were reported across eight prefectures spanning Japan’s northern snowbelt. According to the agency, the death toll by prefecture is as follows:
- Niigata: 12
- Akita: 6
- Hokkaido: 3
- Aomori: 2
- Iwate: 1
- Yamagata: 1
- Nagano: 1
- Shimane: 1
Injuries were logged in a broader swath of the country, across 12 prefectures. The fatalities and injuries were recorded from January 20 through the afternoon of February 2, when the Fire and Disaster Management Agency released its latest nationwide summary. (nippon.com)
Niigata’s snow infrastructure, and its risks
Niigata officials said two men engaged in snow clearing on Sunday were swept away in a “flowing snow gutter,” a waterway used to carry shoveled snow to rivers-a common feature of Japan’s heavy-snow districts. Search operations continued after the pair disappeared while working to clear a blockage inside the open channel in Tokamachi City. (uxtv.jp)
To manage the cumulative toll-97 dead and injured in the prefecture-the Niigata government established a heavy snow response headquarters on Monday led by the governor, a move that elevates the situation to a prefecture-wide emergency posture and frees up personnel and interdepartmental resources for rapid snow-removal support, coordination with municipalities, and targeted public safety measures.

The “flowing snow gutter” system (ryūsetsu-kō) is integral to winter life in parts of northern Japan: controlled streams move dumped snow toward waterways on set timetables, easing the burden on streets and households and reducing the need for trucked snow disposal. But when channels clog, currents and hidden voids can turn routine work hazardous, especially for older residents clearing snow around homes and farm buildings. Municipal guidance in Hokkaido and Niigata describes the gutters as open or covered watercourses that must be used during scheduled flow periods, with strict safety precautions such as never working alone and keeping a safe distance from inlets and inspection hatches.

Why this matters beyond Japan
Japan’s Sea of Japan coast is among the snowiest inhabited regions on Earth due to a seasonal pattern: frigid, northwesterly winds sweeping off Siberia draw moisture over the Sea of Japan, build dense cloud bands, and deliver intense, orographic snowfall when they hit mountain ranges. This pattern-often called “sea-effect” snow-has again dominated late January and early February, with weather authorities flagging heavy accumulations and transport disruptions from Hokkaido down through Hokuriku.

The human cost also intersects with a demographic reality. In official disaster white papers, Japan records that a large share of winter fatalities occur during snow-removal work and that roughly two-thirds to four-fifths of those who die in severe-snow seasons are 65 or older. Clinical studies from Niigata’s snow country report that most rooftop fall patients are older men and sustain multiple fractures-evidence that the physical demands of snow clearing amplify risk in aging communities where labor-intensive winter maintenance still falls on residents rather than professional contractors.

For governments in other snow-exposed regions-from the northern United States and Canada to parts of Europe-the current season in Japan highlights how climate variability, infrastructure design, and aging populations converge to turn routine winter tasks into a public safety and social-care challenge, not just a weather story.
Public warnings and emergency support
With the casualty count rising since January 20, central authorities have urged residents in affected regions to avoid working alone, secure lifelines such as mobile phones and neighbors’ contact details, wear helmets, and take extra care near waterways, rooftops, and snow gutters when removing snow. Local governments have used community broadcast systems and social media to reiterate that residents should wait for scheduled snow-gutter flows and follow municipal safety rules.
In Aomori Prefecture-where snow depths have closed schools and strained municipal clearing capacity-the governor requested Self-Defense Forces assistance for emergency roof clearing at elderly households; a Ground Self-Defense Force unit deployed Monday under Japan’s disaster-relief framework, which typically operates upon a prefectural governor’s request and enables central funding support for the operation.

Japan’s legal and institutional toolkit for extreme snowfall reflects decades of adaptation. Nearly half a century of policy underpins the designation of Heavy Snowfall Areas and Special Heavy Snowfall Areas, enabling funding and infrastructure-from road snow-melting pipes to community snow disposal channels-under national laws enacted in the 1960s. Those designations under the country’s Act on Special Measures concerning Countermeasures for Heavy Snowfall Areas guide how local and national authorities plan, finance, and prioritize winter countermeasures, including the installation and upkeep of systems like flowing snow gutters.
Transport and operations under strain
The winter pressure pattern that set in on January 20 brought repeated bursts of heavy snow across the Sea of Japan side, prompting airlines to cancel flights at New Chitose Airport near Sapporo and forcing rail operators to suspend the Akita Shinkansen on safety grounds that day. Advisories for “significant heavy snow” persisted in multiple prefectures through the following weekend as accumulations outpaced removal in some cities and highway closures and delayed freight trains added knock-on economic pressure.

For central ministries and local disaster management offices, the operational question now is how long the heavy-snow window will persist and whether current resources are sufficient if similar conditions recur later in the season. Prefectures are balancing residential safety, transport continuity, and medical readiness-especially in communities where older residents shoulder the dangerous work of roof clearing and where hospital capacity can be quickly strained by falls and hypothermia cases.

As of 1:30 p.m. Monday, February 2, the Fire and Disaster Management Agency’s nationwide tally stands at 27 dead and 290 injured since January 20; Niigata Prefecture’s heavy snow response headquarters remains in operation as weather authorities warn that further snowfall could renew the strain on both local infrastructure and emergency services.
