KDDI Corp. was recognized Friday for its female empowerment efforts, while Nissan Motor Co. saw its winning streak come to an end in the latest round of awards aimed at promoting diversity and inclusion in corporate Japan.

The first 2015 J-Win Diversity Award, which honors innovative organizations that find ways to advance women in the workforce, was presented to KDDI by the Japan Women's Innovative Network, a Tokyo-based nonprofit organization.

KDDI, a provider of mobile phone and Internet services, was once Japan's sole international telephone company. It was selected from 59 firms competing in both company-wide and individual manager efforts to promote women's participation in the workplace.
