How Tatsuya is building a better working world

“I believe that organizations with diverse people are fertile grounds for creativity and innovation. As HR officer at my previous company, I focused on promoting diversity and inclusion.

I want to implement similar initiatives at EY Japan so that diverse people can bring their skills and experience to the table in their own way.

As AI brings changes to society, I am constantly thinking about what only humans can do and promoting innovation that is only possible at EY Japan.”
