Yusuke Bet on American Attempts Over a Safe Tokyo Offer—Then Built Frost Partner-First

Yusuke is CEO of Frost, a San Francisco cool-delivery analytics startup, with Yuya as CTO. Frog invested; Frog community members—Hiroshi on sales, Nami on design, Shimoda on data science/AI—joined the build. The interview sits outside Frog’s usual IC stories: a founder who started trying in his twenties and treated America as non-negotiable.

Entrepreneurship began early. In first-year high school, his father handed him a Kyocera Inamori book when he felt lost about life’s direction; the idea of cutting one’s own path stuck. University brought a CyberAgent new-hire intern track and a path into CyberAgent Ventures (now Capital), but a Seattle study-abroad stretch locked a different conviction: if he founded, it had to be in America, among immigrant founders whose stories he absorbed.

He declined the Japanese offer. Intern peers already launching in the U.S. made “work two or three years in Tokyo first” feel hollow—language and networks would not transfer. Kiyo Kobayashi’s writing argued that San Francisco success made Japanese wins and networks almost irrelevant; more American attempts mattered more. Yusuke took that seriously.

First company Pod Room renovated unused hotel space into capsule stays. With almost no contacts, he networked person by person, raised once the business looked real, and later closed the venture. Looking back he cites thin legal knowledge as a foreign founder, skill gaps at twenty-five or twenty-six around lobbying and strategy, and underestimating industry difficulty—problems a denser community might have softened. The lesson he carries: know which game you are in, learn its rules, prepare, and ask for help instead of solving everything alone. On an India research trip for Pod Room he cold-messaged rival executives on LinkedIn until presidents took meetings—send a hundred, get one reply.

Frost began with a partner search before a product. Introduced to Yuya as a strong engineer leaving a role, Yusuke flew from New York to Vancouver after a Zoom to test values face to face. They shaped the business together; Yusuke prefers people-first over idea-first because pivoting an idea-bound team often means asking people to leave. Ownership shared at the top changes speed. He has watched Yuya shift from IC tech talk toward sales and company direction—founders do everything.

Frog entered via Yuya’s ask for investment and visa/PEO support, then hiring. Yusuke values filtered quality and soft references over open-web volume (hundreds of applicants, including about eight hundred for a part-time role Yuya filtered). Shared West Coast timezones beat Asia’s next-day lag for startup pace. He tells would-be U.S. founders that Japanese entrepreneur communities and information access have lowered the first-step barrier over a decade—interest is enough reason to try.
