History

MOL's history dates back to 1884 with the founding of Osaka Shosen Kaisha, or OSK Line, which quickly became the largest shipping company in Japan.
The company expanded its shipping route and fleet over the following decades, but reduced its fleet to 55 by the end of World War II.
MOL regrew its fleet and shipping services after the war and introduced innovations such as the Kinkasan Maru, the first automated ship in the world, in 1961.
Here are some key milestones in MOL's history:
- 1884: Osaka Shosen Kaisha (OSK) founded
- 1942: Mitsui Steamship Co., Ltd. founded
- 1961: Kinkasan Maru, the first automated ship, introduced
- 1964: MOL formed through the merger of OSK and Mitsui Steamship
Today, MOL is the world's largest ocean-going shipping fleet, operating out of thousands of ports worldwide.

Mitsui OsK Merger

The merger led to improved business results, and the loss brought forward was written off in 1966.
MOL began container services on the California route, joining a space-charter consortium of four Japanese operators.
The company was recapitalized at ¥20 billion in 1968, and at ¥30 billion in 1972, indicating a significant investment in the business.
In 1974, the owned fleet increased to 152 vessels, totaling 6.6 million DWT.
The operating fleet, including owned and time-chartered vessels, grew to 291 vessels, totaling 10 million DWT by 1974.
A major milestone occurred in 2018 with the merger of Mitsui OSK Lines, Kawasaki Kisen Kaisha, and Nippon Yusen Kabushiki Kaisha's container shipping business.
The new joint venture company, Ocean Network Express, was established on April 1, 2018, with headquarters in Japan, a business operation headquarters in Singapore, and regional headquarters in several countries.

Challenges and Restructuring
Mitsui O.S.K. Lines has faced numerous challenges throughout its history, including a major restructuring effort in 1984. This was sparked by the introduction of the mandatory independent action clause in the Maritime Act of the United States, which allowed shipping companies to offer discount tariffs.
The company responded by curtailing expenses and establishing greater competitiveness on its routes. MOL also decided to enlarge its container terminal facilities at Los Angeles and install its own container terminals at Asian ports.
Some of the notable ships in MOL's fleet after restructuring include the America Maru, Aurora Light, Brasil Maru, and Crystal Pioneer, among others.

Restructuring
In 1984, the Maritime Act of the United States was revised, introducing the mandatory independent action clause, which gave shipping companies the right to introduce a discount tariff if registered at the Federal Maritime Commission.
This led to a significant drop in freight rates on North American routes, making it difficult for MOL to remain profitable. Every route between the Far East and the United States made losses, and MOL's business performance deteriorated.
To combat this, MOL worked hard to curtail expenses and establish greater competitiveness on these routes. In the same year, it decided to enlarge its container terminal facilities at Los Angeles and install its own container terminals at Asian ports.
MOL also reorganized its operations on the Pacific routes, dissolving the consortium of six Japanese companies. In 1985, it began a two-company consortium with Kawasaki Steamship's K Line service on the Japan/Pacific southwest route and with East Asiatic Co. on the Far East/Pacific southwest route.

The New York route became the most competitive due to the trend toward intermodal forms of transport. To improve services, MOL introduced a computer booking system in 1984 and enlarged its online system to cover the United States and the Far East in 1986.
However, the New York route became lossmaking after 1986, seriously affecting the company's performance. MOL did not pay dividends between 1987 and 1989.
Here are some of the ships that were part of MOL's fleet after restructuring:
- America Maru
- Aurora Light
- Brasil Maru
- Crystal Pioneer (woodchip carrier)
- Eigen
- Enchanter
- Energia Centaurus
- Grandis
- Envoyager
- Hokuetsu Delight (woodchip carrier)
- KN Arcadia
- Kurenai
- Lambert Maru
- Midnight Dream
- Mona Linden
- Pleiades Dream
- RMC Rigel
- Sea Navigator
- Shiyo
- Vega Dream
- Zebra Wind
Post War
After the war, MS aggressively expanded its fleet and routes to rebuild its pre-war network.
This expansion led MS to apply to the FEFC, but its application was rejected. MS responded by placing non-conference-member ships on the route in 1953.
The conference attempted to resolve the issue, with the British ambassador even publicly criticizing Japan's shipping policies in 1955.
Japan's joining of the General Agreement on Tariffs and Trade (GATT) that same year created an opportunity for resolution, and MS was eventually able to join the conference.

Understanding Macro Events
Understanding macro events is crucial for MOL's business success. The company's global reach and interconnected nature mean that it's essential to stay informed about macro developments that could impact the sector.
Takeshi Hashimoto, the chief executive officer of MOL, relies heavily on the Financial Times (FT) for business insight. He used to read the paper in the morning and have the FT's "pink pages" on his commuting train, but now he stays up-to-date with digital news.
MOL's business is affected by global events, and the company needs to constantly think about resource allocation and which parts of the business to concentrate on or expand. This requires a clear understanding of the "total picture".
The FT's vast network of journalists provides valuable connections between events, sectors, and regions, helping MOL's leadership understand the potential implications and consequences of macro events. For example, during the 1973 oil crisis, MOL's business performance improved, but it soon deteriorated rapidly.

To stay ahead, MOL's leadership must be able to judge the situation and make informed decisions. The FT provides high-quality information that helps them understand the real target of Western countries and the most likely outcomes of events like the war in Ukraine.
In 1979, about 60% of general cargo from Asia to the United States was loaded at newly industrialized countries (NICs), and MOL reorganized its routes in response. This shows how macro events can disrupt established business models and require companies to adapt quickly.
By staying informed about macro events, MOL can anticipate and prepare for changes in the market, ensuring its continued success in the face of uncertainty.

The company's passenger service was eventually joined by a few other Japanese shipping companies in the 1990s, as the demand for sea travel increased. This expansion helped meet the growing needs of travelers.
In the early years, MOP's passenger ships were the only ones of their kind in Japan, catering to a niche market.
