The holding company is JT International SA and headquartered in Tokyo, Japan; Geneva, Switzerland; and Raleigh, North Carolina.

As of 2018, JTI employed around 46,000 people around the world at 400 offices, 27 factories, five research and development centers, and five tobacco-processing facilities.

Previously, JTI operated outside of the U.S., but this purchase gave JTI roughly 10% market share and two of the most popular cigarette brands in the U.S.[9] The three largest Canadian tobacco companies, Imperial Tobacco Canada, JTI-Macdonald Corp, and Rothmans Benson & Hedges, are the subject of the largest class-action lawsuit in Canadian history.

In addition, a number of Canadian provinces are teaming up to sue tobacco companies to recover healthcare costs caused by smoking.

[10] On 1 June 2015, Québec Superior Court Justice Brian Riordan awarded more than $15 billion to Quebec smokers in a landmark case that pitted them against three Canadian cigarette giants, including JTI-Macdonald Corp.[11][12] JTI was ordered to pay 13% of the total, or C$2bn.
