Three Consecutive Years of Superior Accuracy

Trusted Weather Intelligence Across Industries

Independent third-party evaluations consistently rank Weathernews as Japan's most accurate weather service provider for three consecutive years among the nation's top five services. These assessments utilize verification standards established by the Japan Meteorological Agency, providing objective validation of our forecasting reliability.

Our commitment to accuracy extends beyond external validation through rigorous internal performance evaluation. Using comprehensive metrics including accuracy rates and precipitation detection rates, we consistently exceed Japan Meteorological Agency's performance standards. This superior precision results from our proprietary meteorological data collection systems and continuously optimized prediction algorithms.

This proven accuracy and technical excellence has earned the trust of over 2,600 corporate clients across diverse industries. Our meteorological intelligence services are implemented by weather-dependent organizations including manufacturing, retail, logistics, construction, energy, and agriculture sectors where forecast precision directly impacts operational success.

Our solutions enable critical operational decisions including municipal evacuation center activation during typhoon events, retail flood protection measures during heavy rainfall, logistics and manufacturing planning for snow-related traffic impacts, and comprehensive heatstroke prevention programs for construction workers and educational institutions. These applications primarily focus on personnel safety and business continuity planning frameworks.

Additionally, our services support revenue optimization initiatives including e-commerce demand forecasting, energy consumption prediction, retail traffic analysis for staffing optimization, and targeted marketing campaigns based on temperature patterns. Implementation strategies are customized to meet specific client objectives and operational requirements.

Comprehensive Monitoring Network

13,000 Observation Stations Nationwide

Our superior forecast accuracy is enabled by the industry's most comprehensive weather observation infrastructure.

We operate a nationwide weather observation network comprising approximately 13,000 monitoring points, integrating our proprietary observation equipment with approximately 1,300 AMeDAS stations maintained by the Japan Meteorological Agency. Since accurate forecasting requires comprehensive understanding of current atmospheric conditions, our extensive observation network captures detailed meteorological data across Japan, enabling highly precise weather prediction capabilities.

For enterprise clients, we provide the high-performance SoratenaⓇ Pro weather IoT sensor system for comprehensive on-site environmental monitoring. This system observes seven critical parameters including temperature, humidity, atmospheric pressure, rainfall, wind direction, wind speed, and illuminance with minute-by-minute updates. Observation data is accessible through PC and mobile applications, with automated alert notifications for high-risk weather conditions to prevent oversight and enable rapid response protocols. The compact design and straightforward installation process has driven adoption across construction sites, event venues, agricultural operations, and educational facilities for enhanced safety monitoring.

Community Powered Weather Data

200,000 Real-Time Observations Received Daily

Complementing our technical observation infrastructure is our comprehensive Weather Report system, which leverages nationwide user participation to capture detailed current weather conditions. This community-driven approach transforms traditional one-way weather communication into an interactive intelligence network, enabling more accurate and valuable meteorological information delivery.

We receive approximately 200,000 daily weather condition reports including sunny, cloudy, rainy, and snowy conditions, plus 20,000 to 30,000 daily photographs and videos documenting sky conditions, cloud formations, and precipitation patterns. This human-observed data provides critical intelligence that automated equipment cannot capture, including dynamic cloud development, changing sky conditions, and precipitation-related impacts such as flooding and inundation.

Our SoraCamⓇ cloud camera network provides additional observational capabilities through strategic deployment with user cooperation. As of July 2025, 2,500 units are operational nationwide, delivering continuous 24-hour real-time sky condition monitoring across diverse locations. This network significantly enhances our ability to detect localized weather changes and assess disaster conditions in real-time.

1km Mesh Precision Forecasting

Ultra-High Resolution with Real-Time Updates

Our weather forecasting technology is distinguished by exceptional resolution capabilities that enable precise, location-specific decision-making support.

Weathernews delivers weather predictions at 1km mesh resolution, representing the highest available precision in the industry. Beyond resolution capabilities, our forecasting algorithms incorporate detailed regional characteristics and geographical factors, enabling accurate prediction of weather phenomena and regional conditions that conventional models cannot adequately address.

This precision is particularly valuable for localized weather events such as flash thunderstorms, which produce intense rainfall over limited areas spanning only several to dozens of kilometers. Traditional broad-area forecasting cannot adequately reflect these concentrated phenomena. Our 1km resolution accurately captures small but intense precipitation systems in our forecasts. Additionally, detailed elevation modeling enables precise temperature forecasting that supports enhanced summer heatstroke prevention and accurate winter precipitation type determination.

This technology enables location-specific weather prediction for individual work sites and facilities operated by corporate and government clients. Since weather conditions can vary significantly over distances of just a few kilometers, our precision forecasting ensures decision-making is based on accurate conditions at specific operational locations, resulting in improved planning and risk management outcomes.
