Mitsui O.S.K. Lines (MOL) and Japan Airlines (JAL) have partnered with Lloyd’s Register and REGENT Craft to develop the vessel certification and operational approval framework required to deploy fully electric, 300 km/h “Seaglider” vessels in Japan. This historic maritime-aviation alliance aims to navigate complex regulatory landscapes, leveraging advanced wing-in-ground (WIG) effect technology to commercialize zero-emission coastal and island transit by approximately 2030.
Tokyo | June 10, 2026 – In a major move blurring the boundaries between maritime transit and commercial aviation, Japanese shipping conglomerate Mitsui O.S.K. Lines, Ltd. (MOL) and flag carrier Japan Airlines Co., Ltd. (JAL) have launched a joint development project to commercialize next-generation zero-emission transit.
The two industry titans, alongside leading international classification society Lloyd’s Register, have entered into a landmark four-party agreement with U.S.-based marine defense and mobility developer REGENT Craft Inc. The objective: establishing the first comprehensive vessel certification and operational approval framework required to deploy fully electric “Seaglider” vessels in Japanese waters.
The initiative marks the first time a major classification society has collaborated directly within Japan to build a regulatory pathway for wing-in-ground (WIG) effect crafts, laying the critical legal and operational groundwork for commercial rollout by 2030.
Tech Profile: What is a Seaglider?
A Seaglider is a high-speed, zero-emission vehicle designed to revolutionize coastal and regional island logistics. Technically classified as a Wing-in-Ground (WIG) craft, it operates under the principle of aerodynamic ground effect.
What is Ground Effect? Ground effect occurs when a vehicle flies within one wingspan’s distance from the water’s surface. The proximity to the water traps a cushion of high-pressure air beneath the wings, drastically increasing lift while reducing aerodynamic drag.
Regent Seaglider Flight Profile
| Parameter | Operational Detail |
| Asset Class | REGENT Seaglider |
| Cruising Speed | 300 km/h (High-speed regional transit) |
| Altitude Profile | Skims a few meters above sea level |
| Core Technology | Aerodynamic Ground Effect (Wing-in-Ground/WIG) |
By coupling this aerodynamic efficiency with advanced hydrofoiling capabilities for departures and landings, Seagliders achieve the high velocity of regional aircraft at a fraction of the operating costs, all while relying on a 100% electric, battery-powered powertrain.
- Cruising Speed: Up to 300 km/h Urban Air Mobility News
- Environmental Footprint: Zero direct emissions (NOx, SOx, or Carbon) Inspenet
- Target Markets: High-frequency coastal passenger routes, priority cargo delivery, and remote regional island connectivity.
Building the Regulatory Runway for 2030
Because Seagliders occupy the operational grey area between a vessel and an airplane, establishing a clear classification pathway has historically been the primary hurdle to global market penetration.
Under the new agreement, Lloyd’s Register will act as an independent third-party advisor, bringing its extensive technical, safety, and regulatory experience to bear. Crucially, Lloyd’s Register is acting as the first international classification society to certify REGENT’s Seaglider hulls outside the United States.
MOL and JAL will fuse their respective centuries of maritime navigation and aviation safety protocols to satisfy Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
Industrial & Financial Weight Behind the Consortium
This joint development project is built upon years of deep financial integration. Both Japanese transport giants previously made equity investments in the Rhode Island-based manufacturer, JAL via its corporate venture arm in late 2023, followed by MOL’s venture capital subsidiary, MOL Switch LLC, in mid-2024.
The project carries massive commercial stakes. To date, REGENT has amassed a global commercial order pipeline valued at more than $10 billion from ferry operators and regional airlines worldwide, alongside $15 million in tactical logistics development contracts with the U.S. Marine Corps. The company has raised upwards of $100 million from tier-one defense and venture funds including Lockheed Martin, Founders Fund, and 8090 Industries.
Executive Perspectives
The scale of the market opportunity is particularly pronounced in Japan, where over 80% of the population resides near coastal areas.
“Bringing Seaglider operations to Japan represents a significant milestone for REGENT and for the future of coastal mobility,” said Ted Lester, Vice President of Certification at REGENT Craft. “Establishing clear certification pathways in Japan is the critical foundation that makes commercial deployment possible. MOL, JAL, and Lloyd’s Register each bring deep expertise in safety, certification, and operations as we move forward to bring Seaglider technology from vision to reality.”
From the energy strategy perspective, the asset offers an immediate pathway to decarbonizing domestic shipping routes.
“By combining MOL and JAL’s expertise in safe and reliable maritime and aviation operations with REGENT’s innovative technology and Lloyd’s Register’s certification capabilities, we aim to pave the way for Seaglider operations in Japan,” stated Ryota Hayashi, General Manager of the Energy Business Strategy Division at MOL. “We believe this initiative will create new opportunities in passenger and cargo transportation and contribute to a sustainable and advanced transportation network.”
The Strategic Horizon
For MOL, the Seaglider project directly aligns with its corporate Sustainability Issues (Materiality) framework, focusing heavily on environmental stewardship and transition dynamics. By investing early in the certification framework, the coalition is positioned to monopolize a completely new asset class capable of operating at the speed of flight with the accessibility of a local seaport.
About REGENT
REGENT Craft is pioneering the future of maritime mobility through the development and manufacturing of Seaglider™ vessels, high-speed, hydrofoiling wing-in-ground effect (WIG) craft. By operating over the water within a single wingspan of the surface, these vessels combine the speed of an aircraft with the convenience of a boat. As a dual-use company based in Rhode Island, U.S., REGENT has secured global commercial orders valued at more than $10 billion from leading airline and ferry operators worldwide, alongside $15 million in contracts with the U.S. Marine Corps. To date, REGENT has raised more than $100 million from tier-one investors including 8090 Industries, Founders Fund, Japan Airlines, and Lockheed Martin.
