About Us

Air Flow is a whole new breed of creative insights agency.

Our original approach to customer strategy not only utilizes new and custom methods; we also leverage our savvy to bring measurable growth opportunities for many of the world’s preeminent brands.

Based in Tokyo, we also work in the US, UK, Europe, Asia and globally providing qualitative and direct data solutions. Air Flow’s senior expertise means we have executed hundreds of projects over the last 15 years, as well as thousands of interviews in the field.

Our Work


We focus on what people people DO in real life, not what they’re paid to SAY in surveys and interviews.

We’ve overhauled each layer of the research process in fundamentally new ways; because we’ve learned that shoppers rarely do what they say they will… and new growth areas can be found by searching from the bottom up.

Some of our methods include:

Cons observ Deep Observation & Segmentation

shopper data Shopper Data (Small, Direct & Thick Data)

social media Social Media Analysis

cultural insights Cultural Insights Inquiry

eye vis anth Visual Anthropology

We cast our net across a range of sectors including Health & Beauty, Technology & Electronics, Fashion, Food & Beverage, Kids’ & Toy Research, Entertainment, Pharma, Automotive and Travel & Hospitality.

Jeffrey Brouse・Founder & Director

Jeffrey is one of Japan’s most dynamic Insight experts with experience building hundreds of qualitative studies from the ground up. He has worked with some of the world’s biggest brands and loves working with clients to produce unique methodologies, great fieldwork, cultural insight, localized analysis… and always an insightful debrief to top things off.

Jeffrey first came to Japan from his native West Virginia in 1996 and moved here permanently 13 years ago. But he also has a long family history here dating back six decades. His other experiences include successfully running another other agency in Tokyo after getting his research start in Boston ages ago. He has a Bachelor’s from Harvard in Social Studies with a concentration in Japanese Language & Culture. He went on to do further Master’s level work at the U of London’s SOAS. In his spare time you will find him hanging with the locals and hiking Japan’s back trails, ever in search of those elusive untamed lands! He’s been invited to speak on cultural trends at universities, for Marketing & Corporate teams, at the Harvard Club of Japan and at Japan Fashion Week (despite not being a very fashionable fella!)

Yoshie is a bilingual research & insights dynamo with a decade of experience Moderating, planning & setting up sophisticated fieldwork and coming up with creative solutions to clients’ sampling needs. Her ability to transliterate cultural complexities into simple, actionable insights is what makes her an asset at the office and in the field.

Before making her way to the world of insights, Yoshie worked as a bilingual Translator for Japan’s Ministry of Foreign Affairs. In her younger years, she spent several years abroad in the little town of Nelson, NZ and then Boston… where she gained a BA in Sociology from the U of Massachusetts. At Air Flow she has worked on projects as varied as global Pharma to alcohol & beverage to children’s research. If you were to say that eating, sleeping and drinking were not hobbies… like most Japanese, she’d beg to differ!
