TIER IV has been selected for a government-funded project to deploy autonomous shuttle services connecting National Diet buildings in central Tokyo. The Ministry of Economy, Trade and Industry initiative explores accelerating autonomous driving adoption in Japan’s public sector to address driver shortages and aging population challenges in municipalities beyond metropolitan areas.
Highlights
- Autonomous shuttle service launches November 20, 2025, on 3.5-kilometer route connecting government buildings in central Tokyo
- Suzuki Solio vehicles equipped with Autoware open-source autonomous driving software and TIER IV’s robotaxi reference design
- Project will establish standardized specifications and operational processes for future public sector autonomous vehicle procurement
- Real-world driving data analysis aims to address technical challenges of autonomous operations in dense urban environments
Project Overview
The National Diet shuttle deployment represents Japan’s effort to develop frameworks for autonomous mobility services in government operations. The project focuses on creating reference standards that national and local government agencies can apply when procuring autonomous vehicle systems.
TIER IV’s selection for the Ministry of Economy, Trade and Industry project positions the company’s technology as a potential benchmark for public sector autonomous driving implementations. The initiative targets social challenges including workforce shortages in transportation sectors and mobility access in aging communities outside major urban centers.
Technical Implementation
The shuttle system utilizes several key components:
- Vehicle Platform: Suzuki Solio configured for autonomous operation
- Software: Autoware open-source autonomous driving software
- System Architecture: TIER IV robotaxi reference design
- Route: Approximately 3.5 kilometers through central Tokyo government district
Operations commence November 20, 2025, providing real-world testing conditions in complex urban traffic environments. The deployment enables evaluation of autonomous vehicle performance in high-density cityscapes with mixed traffic patterns.
Evaluation Framework
The project incorporates quantitative and qualitative assessment methodologies to analyze operational design domain requirements and development challenges specific to urban autonomous driving. Data collection focuses on:
- Real-world driving performance metrics in complex traffic scenarios
- User experience feedback from government personnel
- Technical limitations and operational constraints in dense urban settings
- Procurement specification requirements for public sector deployments
Analysis results will inform policy frameworks and standardized procurement processes designed to facilitate autonomous vehicle adoption across Japanese government agencies. The findings aim to reduce barriers to implementation for municipalities considering autonomous mobility solutions.
TIER IV develops platforms and services built on Autoware, collaborating with partners internationally to advance open-source autonomous driving software. Autoware is a registered trademark of the Autoware Foundation.
