Hironobu Asai

Chief Executive Officer Asai joined Mizkan after a Bioengineering Master’s 17 years ago and never looked back. His initial area of expertise was production technology.   A large part of this was developing and designing vinegar manufacturing processes and systems. Asai’s next major project was implementing Total Productive Maintenance (TPM) across all Japanese factories. In a varied career, he also served as MD of Mizkan Thailand. As the head of the Finance and Accounting Division, he carried out the acquisition and post-merger integration of R&B Foods in the United States.   Asai’s aim is to create new value by marrying Mizkan’s 211-year heritage and knowledge with the driven and talented Mizkan Euro team. By continuing to inspire with product, recipe, and usage ideas, Asai hopes to build a beloved company with a loyal following. He aspires to keep our Branston, Sarson’s, Haywards, and Mizkan brands on tables everywhere.
