McKinsey in Japan

McKinsey’s Japan office helps Japanese companies as well as multinationals make significant, sustainable progress against their most pressing goals. We provide world-class expertise tailored to the Japanese context and serve 70 percent of the top 50 Japanese companies, including the industry leaders in most sectors. We support client initiatives such as globalization, corporate and business-unit strategy, and operational improvement in functions such as marketing, sales, sourcing, product development, and supply chain.

McKinsey Japan prides itself on recruiting and developing global leaders, and our extensive alumni network includes the founder of DeNA, CEOs of several multinationals such as Twitter Japan, Puma Japan, Apple Japan, and the EVP of Uniqlo, as well as several private equity executives.

The office spearheads research on a wide range of issues, some of which are featured in the recent book Reimagining Japan. Similarly, we convene industry conferences such as our recent Global Energy forum. We have supported over 30 pro bono initiatives and not-for-profit organizations in the last decade, including Sendai City, Nippon Special Olympics, TOMODACHI initiative, and Doctors Without Borders.
