Disaster Prevention System ZEROSAI - Centralized Management of Weather Information for Construction Projects

The Natural Disaster Prevention System ZEROSAI has been utilized by many general contractors since its launch. Since the start of operations, it has been implemented at over 1,000 civil engineering and construction sites and is currently being widely used as a weather countermeasure on construction sites. As a successor service to the Natural Disaster Prevention System ZEROSAI, we will release the Comprehensive Weather Platform ZEROSAI X-AI on February 18, 2026. ZEROSAI X-AI can centrally manage weather forecasts for construction sites, weather and environmental data, and hazard notifications. It allows all personnel on site to visualize various dangers such as sudden heavy rain, strong winds, heatstroke measures during summer, linear precipitation zones, and typhoons. While leveraging the strengths of traditional centralized management, we have newly added an AI-based wind speed forecasting feature. Additionally, various functions such as chatbots have been added or improved, making it even more convenient. For service details and catalogs, please visit our website.

On December 23rd (Tuesday), the Japan Meteorological Agency announced the three-month forecast for January to March. During this period, there will be times when the extension of the Siberian high pressure is weak to the northeast and strong to the southeast, which may lead to the influence of cold air from the west. As a result, temperatures nationwide are expected to be nearly average from January to February. For more details, please visit our company website.

On November 11, 2025, a proposal to revise the "Disaster Prevention Meteorological Information" concerning floods, heavy rain, landslides, and storm surges was approved by the Cabinet. The implementation is scheduled for the rainy season in 2026. This article will explain what disaster prevention meteorological information is, the issues with the current system, and how the new disaster prevention meteorological information will change.

How will the new disaster prevention meteorological information change? 1. What is disaster prevention meteorological information? Disaster prevention meteorological information refers to information related to disaster risks announced by the Japan Meteorological Agency. It is issued when the risk of disasters such as heavy rain, floods, strong winds, lightning, storm surges, and landslides increases, serving as a basis for decisions on evacuation and work suspension. Specifically, it includes alerts and warnings such as "Special Heavy Rain Warning," "Landslide Warning," and "Storm Surge Advisory," which are denoted by the suffixes "warning" or "advisory." It also encompasses various other information, such as "Meteorological Information on Significant Heavy Rain" that alerts to the risk of linearly organized precipitation bands, "Heat Stroke Warning Alerts" during summer, and "Typhoon Information." 2.
