Why MOL? The Reason to choose
Mitsui O.S.K. Lines

Mitsui O.S.K. Lines (MOL) Group has provided safe and reliable transport of a variety of goods, including resources, energy, raw materials, and finished products, supporting the lives and industries of people worldwide for over 130 years. In order to continue fulfilling its role as an indispensable lifeline for societies to the maximum extent possible, we will endeavor to remain the company of choice by customers and partners by adapting to the changing times and market conditions.

MOL’s History: “Spirit of Challenge and Innovation”

MOL, which began as Osaka Shosen (O.S.K. Lines), merged with Mitsui Shosen in 1964 and with Navix Line in 1999, to become one of the world's largest full-line marine transport groups, constantly anticipating customer needs and the demands of the times by leveraging the various histories and cultures of each company after each merger. What has enabled this is MOL's predominant "spirit of challenge and innovation". We will continue to nurture this spirit as we forge ahead to create new value.

The Birth of MOL and the Development of Overseas Routes

Beginning with Osaka Shosen Kaisha (O.S.K. Lines), which was established in 1884 by shipowners in the Kansai area and their combined contribution of 93 vessels, we have grown as a company, underpinning the development of foreign trade in Japan by aggressively advancing into coastal shipping routes and long-distance ocean services amid a dramatic increase in the demand for marine transportation following the Meiji Restoration. In 1930, we introduced the epoch-making "Kinai-maru," a high-speed cargo ship, which established a rapid transport service on the New York route, dramatically shortening the required number of shipping days and achieving great success.

1965: Japan's first car carrier which was equipped with RO/RO system loading/unloading equipment specifically for automobile "Oppama Maru" went into service.

Beyond Turbulent Times

Many Japanese merchant shipping fleets were destroyed during World War II. However, along with Japan’s successful recovery from the devastation of war, we proceeded to rebuild our shipping fleet as the Japanese economy grew. In 1961, we built the world’s first automated ship, the "Kinkasan Maru", that maneuvers the main engine from the bridge. In 1965, we launched the "Oppama Maru," which was equipped with Japan's first RO/RO system loading/unloading equipment specifically for automobiles. We worked to promptly respond to the need for specialized and large-sized vessels, and repeatedly took on technological challenges. This approach has enabled MOL to open up opportunities in new business fields and expand operations in existing fields.

Global Network

The World's Largest Fleet and a Wide Variety of Ship Types


Products, energy, and raw materials necessary for food, clothing, and housing, as well as for industry, are transported by "merchant ships". We operate "specialized vessels" specifically designed for cargoes such as oil, iron ore, and automobiles. In total we have one of the world's largest fleets of 816 vessels and are a "full-line marine transportation group" that handles the transportation needs of a broad range of industries.
In addition, we have improved transportation efficiency by increasing the size of vessels, and have also developed and supplied vessels that match cargo volumes and port conditions to provide our customers with optimal transportation solutions.

Aiming to provide safe maritime operations and environmental initiatives of the highest level in the world.

Marine Knowledge
(MOL + Marine Technology+ Marine Knowledge)

For over 130 years, we have been building Marine Knowledge and Marine Technologies including knowledge about the ocean, knowledge of ship operations, technology for ships, and networks with port authorities and shipbuilding company.

MOL will continue to endeavor to maintain safe operation and environmental protection for the Next Generation with this phrase.

Marine Knowledge

Ensuring safe operation is one of the most important factors in enabling us to continuously provide value service to society through transportation. We will never relax our efforts to strengthen safe operation and will continue to make improvements where needed. In the unlikely event of a problem, all employees will work together to resolve any issues.

Support From the Safety Operation Supporting Center (SOSC)

In 2007, we established the 24 hour, 365 day Safety Operation Supporting Center (SOSC) in the head office building, which operates under the maxim "Never let the captain become isolated". There are always 2 seamen (one of whom must have experience as a captain of a vessel) on watch at SOSC, committed to preventing serious accidents before they happen by grasping and sharing in real time threatening conditions such as bad weather situations, including winter storms, hurricanes and typhoons, and frozen river ports, and volatile political situations in places like the Middle East.

Continual Training and Securing of Excellent Seafarers

In order to prevent human errors, a major cause of maritime accidents, we emphasize training for personnel who are responsible for the world's highest level of safe operation. Training centers in six countries around the world offer a wide range of training from theoretical classroom learning to practical training using actual machines and various simulators. In August 2018, we opened one of the largest maritime academies in the Asia-Pacific region, "MOL Magsaysay Maritime Academy" in the Philippines, which provides training for cadets who will become crewmen in our company and take over the mantle of on board safety.

Strengthening Ship Management

We provide ship management services, including maintenance and management of hulls, engines and other engine parts, and operational support, mainly through our own group companies based in Tokyo, Hong Kong, Singapore, Manila, and London, as well as through ship management companies with which we collaborate. Each of these bases provides a wide range of stable support for seafarers and ships, from normal times to emergencies, by providing detailed support tailored to the needs of each region and having our marine engineers rush to the site in the event of a serious problem.

To date, we have relied on the experience and skills of the personnel onboard to maintain safety and emergency responses for vessels navigating over long distances on the ocean. However, by frequently collecting and analyzing navigation and engine data during operation, storing it in the cloud and utilizing it, we have achieved "ocean visualization". This allows us to monitor, diagnose and troubleshoot vessel situations via land-based maritime controllers, in addition to the onboard crew, thereby realizing further coordination between land and vessel and advanced vessel control.

Using ICT to Support Crew Operations

We use ICT to develop systems that prevent human errors, which account for more than half of the causes of maritime accidents, and at the same time help crew members recognize, assess, and operate the equipment appropriately. For example, we have developed a visual support system for crew members, such as lookout and maneuvering, using AR technology, and a goggle-type crew safety education tool using VR technology, to provide safer and higher quality transportation services.

Marine Technology

Utilizing our accumulated experience and technology in the field of marine transportation and our technological capabilities in ships for reducing environmental impact, we are actively involved in marine business and environmental and emission-free business, which are expected to grow further in the future.

Wind Challenger
Tackling Environmental Issues with Modern Vessels

The MOL Group is enhancing our group-wide initiatives to realize sustainable net-zero greenhouse gas (GHG) emissions in order to solve the ever more serious global environment issues. One of these initiatives is the Wind Challenger Project. In this project, a sail is installed to convert wind energy to a propulsion force in an ambitious attempt to reduce the fuel consumption of large merchant vessels that currently rely on fossil fuels in an effort to reduce the environmental load. Using a sail as a source of additional propulsion force has a big advantage in that it simply adds to other energy saving measures such as switching from heavy oil to LNG or using an alternative fuel such as ethanol, without interfering with energy saving devices below the sea level.

More about Wind Challenger

World's First Ice-Breaking LNG Carrier Explores Uncharted Territory

This project was made possible by leveraging knowledge as well as know-how and partnerships cultivated over years of challenges, such as implementing various special features to withstand the harsh environment in the Arctic Ocean and training the crew to operate there. The high-performance ice breaker enabled navigating through the western route where the ice is relatively thin, and also the eastern route where the ice is thicker depending on the season. Transportation through the Arctic Ocean from the Russian Arctic reduces the voyage distance by about 65% compared to going through the Suez Canal. This contributes to reducing global warming gas emissions.

Additionally, transporting natural resources through the Northern Sea route opens up a new resource supply route to Japan and other Asian countries that import natural resources. MOL is actively engaging in the growing Arctic Ocean project that contributes to stable LNG transportation by accumulating further know-how in operating in the Northern Sea route through this project.

Offshore Business
Leading the Industry by Adopting Pioneering Technologies

The offshore business is a technology-driven field, and the technologies and business models for promoting the business are evolving at a remarkable rate. We have established the Offshore Technical Division to develop technologies such as the Floating LNG Storage and Regasification Unit (FSRU), the Floating LNG Storage and Regasification System (FSRU), and Floating Production, Storage, and Offloading system (FPSO).
As the only Japanese company with experience in the operation of LNG carriers and FSRUs, we are promoting the low-carbonization of the entire group's business portfolio. In response to the growing demand for LNG-fired power generation, especially in emerging countries, KARMOL will be able to offer customers unprecedented solutions to a series of issues, such as cost, time, and environmental friendliness, by providing integrated services from receiving and regasifying LNG using FSRUs to supplying electricity through KARMOL's LNG power generation vessel business. This enables us to offer unprecedented solutions to our customers.

Additionally, we were the first company in Asia and Taiwan to enter into the Service Operation Vessel (SOV) business that is specializing in maintenance operations for offshore wind power generation, which is expected to see increased demand in Japan and the rest of Asia. This vessel will be used in a Dachanghua offshore wind power generation project which will be developed by Orsted in Taiwan from 2022.

We will be exploring business areas to respond to the needs of the upcoming era and further strengthening building and sharing of our human and technical resources to contribute to growing the world economy and protecting the global environment.
