World’s 1st Automated Coastal Container Vessel (MASS) Enters Commercial ServiceNewly built vessel with Level 4 autonomous navigation functions

The Nippon Foundation launched the MEGURI2040 Fully Autonomous Ship Program in February 2020 with the aims of addressing the issue of crew shortages from population decline and reducing accidents caused by human error, by achieving autonomous navigation and implementing stable transport for people and goods.
The coastal container vessel GENBU , the only one of the project’s four Stage 2 ships that was newly built as an autonomous vessel, has completed autonomous navigation demonstration testing, and was certified as an autonomous vessel by the ship classification society Nippon Kaiji Kyokai (ClassNK) on January 26 and passed inspection by the Ministry of Land, Infrastructure, Transport and Tourism as an autonomous vessel (Maritime Autonomous Surface Ships (MASS)) on January 28. The vessel entered regular service on January 30 as the world’s first[1] vessel engaged in “commercial service” carrying regular cargo and equipped with autonomous navigation functions (equivalent to Level 4 of the SAE Levels of Driving Automation[2]). This breakthrough in commercial service is expected to lead to wider social acceptance of autonomous vessels, thereby reducing crews’ workloads and transforming work styles, stabilizing logistics, and enhancing the competitiveness of Japan’s shipbuilding and maritime industries.

Demonstration navigation in Stage 1 of the project, carried out from January to March 2022, successfully carried out autonomous navigation in the congested waterways of Tokyo Bay and of long-distance (roughly 750 kilometers), long-time (more than 18 hours) navigation from Tomakomai, Hokkaido, to Oarai, Ibaraki Prefecture. Stage 2, which is currently underway, is using the knowledge gained from Stage 1 to carry out commercial service of various types of vessels – a passenger ferry, container vessels, and a Ro-Ro (roll on, roll off) vessel – as part of a modal shift toward more environmentally friendly shipping, with the aim of social implementation.

With todays launch of commercial service, the GENBU becomes the second of four vessels equipped with automated navigation functions scheduled to enter commercial service during fiscal 2025, following the passenger ferry Olympia Dream Seto , which entered commercial service in Okayama Prefecture in December 2025.

The Nippon Foundation continues to pursue technological development while also promoting the establishment of rules and laws related to automated and autonomous navigation as well as social understanding, with the aim of having autonomous navigation account for 50% of domestic shipping by 2040.

Speakers’ comments (January 30 press announcement)

Mitsuyuki Unno (Executive Director, The Nippon Foundation)

In addition to automated navigation, the newly built container vessel GENBU has globally cutting-edge technologies including remote engine monitoring and automated berthing and un-berthing, and I am very pleased that this will be the first commercial-use autonomous navigation. Going forward, we will use the GENBU to contribute to the creation of rules for autonomous navigation in Japan and globally, while also helping to strengthen the competitiveness of Japan’s maritime industries, which have high levels of technological strength.

Tsuyoshi Unegochi, President, Ikous Corporation

The GENBU represents “intention” and “challenge” for the future of Japan’s marine transport. Its technologies for automated navigation will support crews as a strong partner for sustainable marine transport, and will help to make the supply chains that underpin the Japanese economy more resilient. I am confident that building more vessels equipped with new technologies like the GENBU will make it possible to improve the “flow” of domestic logistics in a sustainable manner.

Yuichi Osawa, Operating Executive, Supply Chain and Purchasing Operations, S&OP Logi and Indirect Purchasing Unit, Honda Motor Co., Ltd.

Japanlogistics industry is facing the structural issues of labor shortages and environmental impact. With this launch of regular commercial operation for a coastal container vessel with autonomous navigation, we are a step closer to resolving these issues, and the fact that we are at a stage where this will actually be used in logistics workplaces is very significant. I hope that this project will become an established platform for supporting safe and sustainable coastal transport.

Reference: ‘GENBU’ demonstration testing and vessel inspection

The GENBU is a roughly 134 meter long, 700-TEU coastal container vessel, maintained by Ikuos Corporation and operated by Suzuyo Marine Co., Ltd., engaged in container cargo transport on a route between Kobe and Tokyo by way of Osaka, Nagoya, Shimizu, and Yokohama. Coastal transport is important infrastructure, accounting for roughly 40% of Japan’s domestic freight transport (ton-kilometer basis), but it faces the serious issues of aging crews and a shortage of workers. The vessel is a flagship in terms of the project’s goal of “Improving Japan’s circulation” ( meguri is a Japanese word for “flow”), equipped with all of the functions to promote autonomous vessels from the construction stage to design and autonomous navigation.
For the vessel to operate, it needs to be certified as meeting technological standards stipulated by the government. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) established an Advisory Committee on MASS in June 2024 to consider things like safety standards and inspection methods related to MASS, and the group published its findings in June 2025. For a vessel to operate as a MASS, it needs to undergo testing to confirm items including that sensors, (collision avoidance route) planners, and other components operate appropriately, and the GENBU passed inspection as a MASS on January 28, 2026.
The vessel will continue to operate autonomously on commercial routes going forward, and the navigational data collected will be used to formulate additional rules related to autonomous navigation in Japan and internationally.
The maritime industry also has classification societies as third-party bodies to inspect and certify vessels’ safety and quality. Obtaining a classification is a de facto requirement for obtaining hull insurance and financing from financial institutions, and classification societies play a very important role in the industry.
Japan’s ClassNK is one of the world’s leading classification societies, and has established the world’s first MASS classification verification (notation) related to automated navigation. The GENBU is the first vessel to receive this certification, making this a historic first step toward social implementation of automated navigation.

Background and history of MEGURI2040

Although demonstration testing for automated driving is currently moving forward with a focus on the automobile sector, given the technological difficulties in areas including ship-to-shore telecommunications environments and instantaneous obstacle avoidance, and the large amount of funds required for development, there has been almost no development to date for autonomous vessels. At the same time, Japan is a world leader in information and communications technology (ICT), artificial intelligence (AI), and image analysis technology. The Nippon Foundation launched the MEGURI2040 project for autonomous vessels recognizing the possibilities for using these technologies for joint technological development with private sector companies to make dramatic advances in technological development related to autonomous navigation. Stage 1 involved six vessels and carried out automated navigation demonstrations from January to March 2022. Stage 2 began in fiscal 2022 and involves four vessels, with the aim of “commercial service” (social implementation). In addition to technological development targeting Level 4 automated operation, the project is promoting the development of Japanese and international rules, an insurance framework, and the development of peripheral environments in line with the evolving needs of users. Of the projects four vessels equipped with automated navigation functions scheduled to enter commercial service during fiscal 2025, the GENBU is the second to have entered commercial service, following the passenger ferry Olympia Dream Setowhich began commercial service in December 2025.

Land-based Fleet Operation Centers to support automated operation

Two land-based Fleet Operation Centers (FOCs) have been built to support multiple autonomous vessels by making it possible to carry out from land operations that had previously been performed on board, including remote monitoring of the engine area and route planning. This will allow crews to have diverse work styles and increase navigational safety.
