What Halex does
Halex Corporation (株式会社ハレックス / HALEX CORPORATION) is a privately held Japanese weather, earthquake, and disaster-prevention information services company founded April 1, 1993 and headquartered in Shinagawa-ku, Tokyo. Positioned as the "総合気象会社" (comprehensive weather company) of the NTT Data Group, the company operates under Japan Meteorological Agency forecast business permit No. 108 and serves Japanese municipalities, railway operators, construction firms, financial institutions, broadcasters, electric utilities, and technology platforms. Its primary customers include JR Kyushu, NTT, NTT Data, LINE Yahoo, Shimizu Corporation, Yokohama Bank, Hitachi Solutions, Spectee, and S.RIDE, with a deeper captive base among its ~40+ corporate shareholders.
Halex's product portfolio centers on a proprietary 1km-mesh data aggregation platform that combines JMA meso-analysis, ECMWF global forecasts, JTWC tropical cyclone data, and proprietary post-processing, delivered through three solution lines: 気象 (meteorology) anchored by HalexDream! (1km-mesh API) and HalexSmart! (GIS-optimized tile/GeoJSON API for Mapbox, Google Maps, Leaflet, ArcGIS, OpenLayers, Azure Maps); 地象 (geology/earthquake) anchored by なまずきん (Namazukin), the J-Alert relay service launched 2006 supporting the PLUM method; and 海象 (oceanography) served by VMS (Voyage Management Service). Disaster-risk monitoring is delivered via HalexForesight!, with optional Patlite hardware and WowTalk chat integrations, and 24/7 staffed 予報センター (Forecast Center) and 監視センター (Monitoring Center) operations back every commercial product with human-validated forecasts. Most recently, Halex has added a generative-AI Weather Data API (RAG-based, launched April 2025) and the 気象MCP (Weather MCP, β) Model Context Protocol server (March 2026) targeting AI-agent consumption.
The company makes money primarily through recurring API/SaaS subscriptions (HalexDream!, HalexSmart!, なまずきん from ¥40,000/month, 防災さきもりLocation from ¥100,000/month), managed disaster-monitoring services (HalexForesight!), data-monetization to enterprises and resellers, professional services and training (from ¥165,000 per course), hardware resale (ALTER ONE UNIT, ¥3B sales target), consumer product sales (あなたの天気図 at ¥9,680), and licensing/usage of the MCP and Generative AI API. Go-to-market combines enterprise field sales, an extensive partner/reseller ecosystem (Hitachi Solutions, NTT Data, Spectee, Space Shift, Clubnets), inside sales with developer free trials, event-driven demand generation, and an API-first adoption path.

Halex product offering
Product offeringCore offering
Halex provides weather, earthquake, tsunami, and disaster-prevention information services primarily through proprietary cloud APIs and SaaS platforms. Its core product is HalexDream!, a weather data API (DreamAPI / DreamFiles / DreamAll) that distributes forecasts built on 1km-mesh data integrated from JMA, ECMWF, and JTWC, with human expert overlay from a 24/7 staffed Forecast Center. Adjacent offerings include HalexSmart! GIS-oriented severe-weather data, HalexMemory! historical weather data, HalexForesight! disaster risk monitoring, なまずきん (Namazukin) emergency earthquake warning distribution, VMS maritime voyage management, and the new Weather MCP and generative-AI weather data API for AI-agent consumption.
Product overview
Halex (株式会社ハレックス) operates a portfolio of weather, earthquake, and disaster-prevention information products under the NTT Data Group umbrella, with offerings organized around three business solution lines: 気象 (meteorological), 地象 (geological/earthquake), and 海象 (oceanographic). The meteorological core centers on HalexDream! (DreamAPI/DreamFiles/DreamAll) — the proprietary 1km-mesh point-forecast API/feed, and HalexSmart! — a next-generation GIS-optimized weather data API providing tile-format and GeoJSON outputs for direct ingestion into mapping platforms (Mapbox, Google Maps, Leaflet, ArcGIS, OpenLayers, Azure Maps). These data feeds feed consumer-facing services including HalexMemory! (historical data), HalexSmile! (web weather service), and HalexForesight! (the disaster-risk monitoring system that visualizes, predicts, and alerts on weather threats with optional Patlite hardware and WowTalk chat integrations). The geological business is anchored by なまずきん (Namazukin) — the long-running emergency earthquake early warning service (since 2006) supporting the PLUM method — with associated products including Namazukin Desktop (PC app) and 防災さきもりLocation (location-aware safety confirmation). The oceanographic line is served by VMS (Voyage Management Service). Layered on top are complementary services: 防災気象情報 利活用講座 (municipal training), 気象データ活用無料相談室 (free consulting), あなたへの天気図 (historical weather maps as gifts), and ALTER ONE UNIT (resold image-clarification hardware). Most recently, Halex has layered an AI strategy on the data core: a 生成AI用気象データAPI (RAG-based generative-AI weather API, launched 2025-04-01) and the 気象MCP (Weather MCP) Model Context Protocol server (β) for AI agents, alongside the launch of global weather data services using ECMWF (2025-10) and JTWC (2025-12) models.

Halex competitors and assessment
Company assessmentBroad incumbents
- DTN: US-based provider of weather, climate and agricultural intelligence for agriculture, energy, aviation and transportation enterprise customers. Comparable as a vertical-focused B2B weather data incumbent competing for similar enterprise segments (agriculture, logistics, infrastructure) that Halex serves via Kubota KSAS, S.RIDE and railway customers.
- The Weather Company (IBM): Global weather data and forecasting business owned by IBM, offering enterprise APIs, media solutions and AI-driven forecasting at massive scale. Comparable as a broad incumbent that Halex competes against for global enterprise customers and that may commoditize the AI-agent weather layer Halex is targeting.
- AccuWeather: US-based global weather media and data company providing enterprise APIs, forecasts and severe-weather alerting worldwide. Comparable as a broad incumbent whose enterprise data products overlap with Halex's ambitions for international expansion via ECMWF/JTWC-sourced data.
Emerging players
- Visual Crossing: Provider of weather and climate data APIs focused on historical and forecast data for analytics and BI use cases. Comparable as an API-first competitor to HalexMemory! (historical weather data) and HalexDream! for analytics-oriented enterprise buyers.
- OpenWeather: Global weather data API provider offering free and paid tiers across current, forecast and historical weather with strong developer adoption. Comparable as a developer/API-first weather data competitor that may pressure HalexDream!'s pricing on usage-based tiers for SMB and developer customers.
- Baron Weather: US-based weather data and visualization company offering Baron Lynx for broadcasting and APIs/services for enterprise and government. Comparable as a focused weather data vendor targeting broadcasters, public safety and infrastructure operators — overlap with Halex's HalexForesight! and Namazukin customer base.
- Tomorrow.io: AI-native weather intelligence platform offering global hyperlocal forecasts and an enterprise API targeting logistics, aviation and on-demand businesses. Comparable as an emerging AI-first weather API player competing for the same AI-agent and enterprise use cases Halex is pursuing with Weather MCP and the generative-AI RAG API.
- Meteomatics: Swiss weather data company providing high-resolution global forecasts and a robust enterprise API used across aviation, energy and insurance. Comparable as a high-resolution, API-first European peer whose global forecast offering intersects with Halex's recently launched ECMWF-based global weather data service.
Direct peers
- Weathernews Inc. Japan's largest private weather information company, listed on TSE, serving enterprise, maritime, aviation, broadcasting and consumer markets with proprietary forecasting, APIs and a major mobile app. Directly comparable as the dominant Japanese B2B/B2C weather services incumbent competing for the same enterprise accounts.
- Japan Weather Association (日本気象協会): Non-profit meteorological service provider offering forecasts, disaster-prevention information and weather data services across Japan. Directly comparable to Halex in the Japanese forecast-data and municipal disaster-prevention market, and notably listed as a Halex shareholder and channel partner.
