Corpy, Aiming for Mission-Critical AI, Collaborates with JR East on Pantograph Damage Detection AI for Yamanote Line
Corpy & Co. has partnered with JR East to pilot an AI-powered pantograph damage detection system for the Yamanote Line, starting April 2026. This system aims for early detection of pantograph failures, mitigating critical risks like train delays and stoppages, and improving inspection and recovery efficiency. It's a significant step to enhance safety in mission-critical railway operations through AI image analysis.

Corpy & Co., Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Kohei Yamamoto; hereinafter "Corpy"), an AI startup originating from the University of Tokyo and Inria, France, which supports the realization of mission-critical AI with XAI & QAAI technology, will jointly implement "AI-powered image analysis of pantograph surveillance cameras," one of the advanced equipment inspection measures during transportation disruptions announced by East Japan Railway Company (Headquarters: Shibuya-ku, Tokyo; hereinafter "JR East") at its president's conference on March 10, 2026, to be launched in fiscal year 2026.
Starting in April 2026, a system will be trialed that analyzes images captured by pantograph surveillance cameras in real time using AI to detect pantograph failures early.
This system utilizes object detection AI and damage detection AI to extract images of damaged pantographs from images captured by pantograph surveillance cameras and reports these anomalies.
Background and Technical Value of This Initiative
Pantograph failures are a serious risk directly leading to train delays and service suspensions. By utilizing AI image analysis, we will build a system to grasp pantograph damage early. This aims to prevent the spread of equipment damage and to streamline inspection and restoration work, reducing work time.
Main Technical Features of the Developed AI
- Object Detection AI: Real-time detection of pantographs from images of trains in motion.
- Damage Detection AI: Highly accurate determination of the presence or absence of damage/anomalies from detected images.
- Mission-Critical Response: Trialing robust AI in outdoor environments where environmental changes and disturbances occur.
History of Co-creation with JR East
Corpy and JR East began their co-creation in April 2025. In May of the same year, at the "11th JR East Startup Program DEMODAY," they received an Excellence Award for "Robust AI," which combines the robustness of autonomous driving AI with the accuracy of exterior inspection AI for manufacturing.
Subsequent proof-of-concept achieved high accuracy in pantograph detection and pass/fail judgment. As the importance of real-time detection increased, they transitioned to full-scale technical development, leading to this trial implementation.
Future Outlook
Corpy will continue to improve AI accuracy and ensure reliability through the trial implementation on the Yamanote Line, aiming for full-scale implementation on the Yamanote Line and further enhancing railway safety in the Tokyo metropolitan area. Leveraging the know-how gained from this project in "mission-critical AI implementation under harsh on-site environments," Corpy will further promote the social implementation of AI in safety-first domains such as railway, energy, and manufacturing industries.
