Identification of Materiality (Key Issues)
As a weather-focused company guided by our founding philosophy of “to be of service to people in times of need,” we strive to build a world where human society, business, and the natural environment can thrive together through weather-centered value creation.
In pursuit of a sustainable society, we have identified five key material issues to address as priorities, selected by weighing pressing social challenges against our business activities and core values.
We first identified Climate Change Mitigation, Building Resilient Cities, and Communities Living in Harmony with Nature as areas where our business directly creates value for society. We then identified Innovation & Partnership and Diversity & Inclusion as the essential foundations that enable this value creation.
We are also committed to strengthening governance as the management foundation that underpins all of these efforts.

Climate Change Mitigation
Consider a large cargo ship transporting goods from San Francisco to Tokyo. What route and speed will allow it to travel safely while minimizing CO₂ emissions? Or a power company facing higher-than-expected temperatures the next day — how should it plan its generation schedule to ensure stable supply while avoiding excess output and unnecessary emissions?
At Weathernews, we help our customers optimize their operations and reduce their environmental impact every day, delivering tailored solutions powered by the latest technologies including AI.
We also work closely with our customers to track and report the CO₂ savings generated through these recommendations, building frameworks for sustainable growth across the industry and society as a whole.

Building Resilient Cities
We provide weather and climate information to help protect lives, property, and economies from natural disasters. We also support city planning that draws on years of knowledge and experience in managing climate risks, alongside systems and technologies designed to enable rapid recovery.
Weathernews delivers weather risk management solutions for transportation networks including railways, roads, aviation, and maritime operations. Through high-precision forecasts informed by user-submitted Weather Reports and our own proprietary observations, we work to reduce the impact of extreme weather events such as heavy rain, strong winds, and snow. We have built systems that strengthen disaster response and speed up recovery, including delivering road closure information to administrators and sending timely alerts for inspection and restoration.

Communities Living in Harmony with Nature
Through co-creation with our supporters, we create communities that enjoy nature and contribute to biodiversity conservation. We also aim for a sustainable society that makes the most of nature’s diverse functions, balancing enriched everyday life with disaster resilience in times of need.
Under the theme of “Communities Living in Harmony with Nature,” Weathernews promotes supporter-participation ecosystem monitoring (such as the Sakura Project) and technical support for Nature Positive Sites (Japan’s “Nature Symbiosis Sites”). Using weather data and IoT sensors, we work to visualize and quantify nature’s functions, such as water resource recharge and flood mitigation. Through nature-based solutions (NbS) for disaster prevention and mitigation, we contribute to building communities that coexist with nature.

Innovation & Partnership
We pursue innovation in weather and climate technologies that support the economy, society, and the environment, with the goal of ensuring that people everywhere can access the weather information they need, when they need it.
Weathernews continuously improves forecast accuracy through AI and big data, while expanding our observation networks with new sensors and devices. To deliver information quickly and accurately, we are strengthening our capabilities in disaster prevention and mitigation. By providing weather services across a wide range of channels, we are committed to making reliable weather information accessible to all.

Diversity & Inclusion
We are committed to providing a fair and equitable working environment for people around the world who share a passion for weather and climate, empowering each individual to reach their full potential.
Weathernews recognizes and rewards motivation and ability fairly, regardless of gender or nationality. Through training programs, career support, flexible work arrangements, and a workplace that prioritizes health and safety, we are dedicated to the sustainable growth of both our people and society.

Materiality Identification Process
STEP 1: Identifying Social Issues
Referencing international sustainability disclosure guidelines (GRI, SASB, ISSB, TCFD, TNFD, etc.) and the evaluation criteria of ESG rating agencies, we broadly identify environmental and social issues related to our business and value chain, and create a long list of social issues to be assessed.
STEP 2: Assessing Importance (Materiality Mapping)
We evaluate the identified issues along two axes: “importance to stakeholders (our impact on the environment and society)” and “importance to our company (the impact of environmental and social issues on our business and finances),” and create a materiality matrix.
STEP 3: Organizing Materiality
Based on the mapping results, and in light of consistency with our mission and medium-term management strategy, and with reference to dialogue with external experts as needed, we organize and consolidate related social issues and identify the key issues (materiality).
STEP 4: Deliberation and Decision
The Sustainability Committee and the Board of Directors deliberate on the appropriateness of the materiality and make the final decision.
If significant changes occur in the business or social environment, we review the materiality as necessary.
