Kanto Railway Launches Autonomous Bus Services in Tsukuba

Tsukuba Consortium Begins Full-Scale Autonomous Bus Operations

The Tsukuba Consortium for the Promotion of Autonomous Driving Implementation in Society announced that it will launch full-scale autonomous bus services on October 2 along the Tsukuba University Loop route operated by Kanto Railway Co Ltd. The service represents the transition from autonomous bus trials toward scheduled implementation, with fiscal 2026 designated as the year for operating the service under a defined timetable. During this phase, the consortium will use Level 2 autonomous buses equipped with advanced driver assistance systems. The initiative is intended to build on the experience and operational insights obtained through autonomous bus trials conducted during fiscal 2025.

Five Members Will Cooperatively Operate the Service

The autonomous bus program will be operated cooperatively by five consortium members: Kanto Railway, KDDI, KDDI Smart Mobility, Tsukuba City, and the University of Tsukuba. Each organization is part of the consortium framework supporting the implementation of autonomous driving on the Tsukuba University Loop route. The arrangement brings together a railway and bus operator, mobility and communications companies, the local government, and an academic institution within a single operating structure. This cooperative model will support the transition from previous trials to scheduled autonomous bus operations while maintaining the consortium's focus on practical implementation and continued development.

KDDI Provides Remote Monitoring and Communications

KDDI will provide remote monitoring and communications for the autonomous buses operating on the route. These functions form part of the operational framework for the Level 2 service planned for fiscal 2026. The consortium's implementation follows autonomous bus trials conducted through fiscal 2025, allowing the participating organizations to apply experience gained during those activities to scheduled operations. The fiscal 2026 service therefore represents an implementation phase rather than another trial-only program, while the consortium continues working toward a higher level of autonomous driving capability for subsequent operations.

Level 4 Autonomous Bus Target Set for Fiscal 2027

The consortium aims to implement Level 4 autonomous driving buses during fiscal 2027. Level 4 autonomous driving refers to fully autonomous operation under certain conditions, representing a higher level of automation than the Level 2 service planned for fiscal 2026. The stated progression establishes a two-stage implementation path: scheduled Level 2 autonomous bus operations during fiscal 2026, followed by the targeted introduction of Level 4 autonomous driving buses in fiscal 2027. The planned transition will allow the consortium to build on operational experience as it advances toward more highly automated bus services on the route.

Tsukuba University Loop Moves Into Implementation Phase

The Tsukuba University Loop will serve as the operating route for the full-scale autonomous bus service, with Tsukuba City and the University of Tsukuba participating alongside the transport, communications, and mobility companies in the consortium. The fiscal 2026 schedule is based on Level 2 autonomous operation and follows the autonomous bus trials completed through fiscal 2025. By moving to a defined operating schedule, the consortium is putting the technology into a practical service environment while retaining a stated objective of progressing toward Level 4 autonomous driving in fiscal 2027.

Industry Impact & Outlook

The move from autonomous bus trials to scheduled Level 2 operations gives the consortium an opportunity to apply accumulated operating experience in a practical public-service environment, while the fiscal 2027 Level 4 target establishes a clear next phase for the Tsukuba University Loop. The participation of Kanto Railway, KDDI, KDDI Smart Mobility, Tsukuba City, and the University of Tsukuba also demonstrates the importance of cooperation among transportation operators, technology providers, government, and academia for autonomous mobility implementation. The next significant development will be progress from the fiscal 2026 Level 2 service toward the targeted Level 4 autonomous bus operation.

Frequently Asked Questions

When will the Tsukuba autonomous bus service launch?
The full-scale autonomous bus service on the Tsukuba University Loop is scheduled to launch on October 2. During fiscal 2026, the consortium will operate Level 2 autonomous buses according to a defined schedule, using advanced driver assistance systems as part of the service. The program follows autonomous bus trials conducted through fiscal 2025 and represents the implementation phase of the initiative. The consortium has also stated an objective of introducing Level 4 autonomous driving buses during fiscal 2027, subject to the planned progression of the program and its operating framework.
