Global JSG Leader's Message

As a transformation partner of Japanese companies

The Japanese Services Group was founded in 1975 to support business foundation establishment and growth in Japanese companies expanding overseas. Since then, Deloitte members from Japan as well as members from around the world have worked together to deliver services to our clients.

The environment surrounding Japanese companies is changing dramatically in the face of issues concerning climate change, geopolitics, and Japan’s international competitiveness. Conventional wisdom and ways of doing things no longer apply in an increasing number of cases. In other words, if Japanese companies are to achieve sustainable growth in overseas markets going forward, it is critical that they transform themselves in various areas.

The Japanese Services Group is committed to helping Japanese companies transform their overseas operations, tapping into the Deloitte Global Network’s front-line knowledge and experience in a wide array of fields as well as our relationships in various regions and countries.
