Founder Profile
Hiroaki Mori / Representative, Three Plus Six LLC
Hiroaki Mori joined Hakuhodo in 1990 and spent the following three decades across account management, marketing, brand consulting, and global project direction. He was posted to TBWA\Chiat\Day Los Angeles, then served as COO of TBWA\Hakuhodo\China in Guangzhou. Upon returning to Japan, he led McCann Erickson Tokyo as Representative Director and CEO for five years and nine months.
In June 2023, after 33 years in corporate life, Mori went independent. Drawing on his accumulated experience and professional network, he now designs -- as an independent agent from Kawagoe -- the strategy, meaning, and relationships that businesses need to grow.
He writes regularly on note, X, and LinkedIn about marketing, organizational thinking, first principles, and the dynamics of advertiser-agency relationships.
