Our History

In 1975, the arrival of the 21st century was no longer that far away. Zenken Corporation was founded in this year as a company promoting language education, based on the belief that the coming 21st century would be an increasingly global era and that human resources with an international perspective would be able to make significant contributions to society.

Now, as we look ahead to the acceleration of the 'global inbound', where Japan will become increasingly internationalized with more foreigners arriving for work and travel, we at Zenken continue to develop our business with the strong conviction that creation of global human resources and opportunities for people-to-people encounters through our IT and language education services will lead to the development of a more prosperous society.
