I studied Japanese at UC Berkeley and made an early bet that real cultural and language fluency in a major non-English market would be worth more than another line of generalist experience. That bet has shaped everything since. My first job out of that world was inside a cult Japanese fashion house in Tokyo, where I was the only native English speaker in the office for most of my time there, and learned what genuine craft and brand discipline actually look like up close. Later, my wife and I built a craft beer import business in Shanghai from nothing — cold calls, container shipping, distribution we built by hand — which taught me, permanently, what it costs to build something with no safety net.

Then came the chapter that defined the rest: most of a decade building the Japan business for a global wellness e-commerce company. I took it from a fragile operation propping itself up on a few lucky products to a fully localized, multi-channel business — marketplaces, payments, paid media, brand, compliance, the whole stack. I navigated a once-in-a-generation currency shock that made our products dramatically more expensive overnight, and led the strategic pivot that turned a moment of real vulnerability into one of the more effective growth strategies I've been part of. In my last years there I helped run international strategy across a portfolio of markets worldwide, building the frameworks the company used to decide where to put its money.

Across all of it, the same pattern: dropped into something ambiguous and high-stakes in an unfamiliar market, and asked to build. I'm at my best there. I'm an operator first — someone who has carried the number, not just advised on it — and I built Zelkova Advisory to bring that to brands serious about Japan.
