"Tokyo Bay eSG Project R5 Priority Projects" Results Report

A business group consisting of Nomura Real Estate Co., Ltd. (lead operator, Headquarters: Minato-ku, Tokyo / President and CEO: Daisaku Matsuo), Shimizu Corporation (Headquarters: Chuo-ku, Tokyo / President: Tatsuya Niimura), ANA Holdings Inc. (Headquarters: Minato-ku, Tokyo / President and CEO: Koji Shibata), Aero Toyota Co., Ltd. (Headquarters: Koto-ku, Tokyo / President and CEO: Hiroshi Kato), Kidou Systems Inc. (Headquarters: Sumida-ku, Tokyo / CEO: Akihito Shiono), Eightknot Co., Ltd. (Headquarters: Sakai City, Osaka / Representative Director: Yuto Kimura), and Tokyo Water Taxi Co., Ltd. (Headquarters: Minato-ku, Tokyo / President and CEO: Tomoaki Ishii) has been promoting a project since October 2023. This project, titled "Construction and Operation Demonstration of a System for Realizing Land, Sea, and Air Multimodal MaaS Centered on a Floating Port for Flying Cars (eVTOL)" (hereinafter referred to as "this project"), was selected under the "Next-Generation Mobility" application theme for the R5 fiscal year of the Tokyo Bay eSG Project "Priority Projects" *1 implemented by the Tokyo Metropolitan Government.

In December 2025, the second demonstration experiment for this project was successfully conducted. This included a landing and takeoff demonstration by a helicopter, simulating a flying car, on a floating port installed in the open sea, as well as an operation demonstration by an autonomous vessel *3. Furthermore, verification of operations at terminal facilities, functional verification of the Seamless Connecting System *4 that supports the interoperability of various mobilities, and operation demonstrations by multiple autonomous robots were also carried out.

The initiatives of this business group related to the "Tokyo Bay eSG Project R5 Priority Projects" will conclude at the end of March 2026, marking the end of the project period. Based on the achievements and knowledge gained from this project, the business group will continue its efforts toward the social implementation of next-generation land, sea, and air mobility, contributing to the realization of a richer society by strengthening urban functions and solving social issues such as regional revitalization.

*1 A project that utilizes the Central Breakwater as a demonstration field to implement cutting-edge technology for the realization of a sustainable city where nature and convenience merge. *2 eVTOL (Electric Vertical Take-Off and Landing aircraft) refers to a small aircraft that uses electric motors to rotate multiple rotors for vertical takeoff and landing. Also known as "flying cars," they are being developed worldwide as new mobility solutions to contribute to a richer and more sustainable society by alleviating traffic congestion and addressing global warming. *3 Autonomous navigation: Technology that allows a vessel to perceive its surroundings, make decisions, and control itself without human intervention. *4 A system that supports the interoperability of various mobilities across land, sea, and air.

**[Demonstration Theme]** Construction and Operation Demonstration of a System for Realizing Land, Sea, and Air Multimodal MaaS Centered on a Floating Port for Flying Cars (eVTOL)

**[Roles of Each Company in This Project]** (Image of company roles is present here in the original, but text content is not provided.)

**[Demonstration Specifics]**

**① Floating Port** A floating port for flying cars was installed in the open sea (outside closed waters), and a landing and takeoff demonstration was conducted using a small helicopter. This verified whether the port possesses performance levels that meet national standards for vertiports *5, even in open waters susceptible to waves and wind.

**② Terminal Facilities** Assuming a vertiport *5 equipped with two FATOs *6, operations such as security checks and passenger guidance at the terminal facilities were verified. The number of personnel required for operating facilities of a similar scale and passenger flow plans were confirmed, and areas requiring mechanization and labor-saving for procedures were identified.

**③ Autonomous Vessel** An autonomous navigation demonstration was conducted between Hinode and Umi-no-Mori. Improvements were made to the collision avoidance maneuvering algorithm and user interface since the first demonstration. After reflecting the improved software, it was confirmed that the vessel could autonomously navigate the route without issues.

**④ Autonomous Robots** System improvements, which were identified as challenges in the first demonstration, were implemented. In addition to cooperative control of multiple units, the operation of autonomous robots based on operation notifications was verified.

**⑤ Seamless Connecting System (SCS)** It was confirmed that the movements of multiple different types of mobility could be managed on a single software interface. Furthermore, communication issues identified in the first demonstration were addressed, and operation commands could be issued to autonomous robots.
