A German national, Nadine received her education at WHU – Otto Beisheim School of Management (Germany), Ecole Supérieure de Commerce de Grenoble (France), and Australian Graduate School of Management (Sydney).

MASAE ARAKI coaches executives and senior leaders of global businesses, helping them to establish behaviors that enhance their own learning and development. She guides her coachees to tap their own internal strengths to prepare for transitions to broader responsibilities.

Raised and educated in Japan, Masae earned a graduate Certificate in Executive and Professional Coaching from the University of Texas’s School of Management and Organizational Behavior Studies. She is now recognized by ICF as a Professional Certified Coach (PCC). She recently gained a Hogan assessment certification. Masae is equally able to coach in Japanese and English.

Masae’s initial employment was at the Akasaka Prince Hotel, after which she moved to the Tokyo office of Ferrero, the Italian confectioner, to become logistics manager. Her responsibilities included marketing and sales as well as logistics, and included working closely with Glico, an Osaka-based alliance partner of Ferrero, to plan strategies for marketing, sales, and importing. When Ferrero tripled its size within one year, Masae took the lead in reducing employment costs by, among other things, revising its logistical systems. Her responsibilities frequently took her to Italy, Belgium, Luxemburg, Australia, and Hong Kong. After 13 years, Masae left Ferrero and moved to Los Angeles to accept a position as a market researcher with Nesstech International. A few years later, she returned to Tokyo and became an independent market consultant, helping expanding companies to develop new markets, identify global trends, and adapt products. For example, she assisted the manufacturer of the SteamFast steam cleaner to adjust its product for Japanese users, leading to millions of dollars in sales.

Based in Tokyo for the past several years, Masae coaches business leaders and high-potential managers in a wide variety of industries. Among her clients are the Japanese firms NTT Group, Recruit, Reit Japan, Joyful Restaurants, and Pacific Golf Management; and the American firms Belkin International, Hyatt Hotels, and Bloomberg.

Masae is a director of the Japan Chapter of ICF, for which she oversees education and credentials, organizing seminars for coaches in both Japanese and English. In addition, she created her own proprietary series of Core Competency programs; ICF accredited this program and authorizes Masae to award ICF Continuing Coach Education certificates.

Masae lives in Tokyo, where she enjoys yoga, ballet, and playing piano to recharge. Although she likes to travel abroad for business and leisure, she also greatly values spending time with her family and friends in Japan.

Roger often serves as a strategic thinking partner for his coachees. One executive wrote that, Roger was able to exhibit empathy and compassion and an active listening style that proved invaluable. His greatest gift was his ability to ask probing opened-ended questions. These questions caused me to think about the motivations behind my motivations. He gave me the freedom to thoughtfully work through some of the issues and, at times, was able to give a different perspective for my consideration. A Japanese CEO wrote that, …he gave me several valuable hints to notice and begin to rethink things more deeply and practically. He tried to understand my business and raised several meaningful questions to get the clear picture of my company.
