Launched in 2017 as a joint venture, ONE inherited the container shipping operations of its parent companies, corresponding to a combined fleet capacity of about 1.4 million TEU.

[4] The company was formed as part of a larger process of consolidation that was occurring in the container shipping industry at that time, affected by poor profits and surplus capacity.

Sailing under Japanese flag, the vessel operates on THE Alliance PN2 service calling Japan, China, US and Canada with a total capacity of 8,560 TEU.

The first deployment was instructed towards North America East Coast, after calling several loading ports in China, Hong Kong and Singapore.

[18] On 19 April 2021, ONE has announced the formation of a new Green Strategy Department, that will be involved in environmental sustainability projects, such as the successful trial of bio-fuel to power the MOL Experience container ship.

[21] The magenta colour scheme was inspired by the cherry blossom trees, one of the national symbols of Japan, where the mother companies are located.

[25] A tonnage review was scheduled to happen within 18 months from the operations beginning, in order to be competitive on all services by using the most recent, technological and efficient ships available to be built.
