Find engineers and operators at companies in Tokyo

Tokyo is one of the densest markets for technology talent in the world. The list above ranks the largest companies headquartered in Tokyo by current headcount, drawn from public LinkedIn and Crunchbase records. With 2,672 matching companies in our index, the depth of engineers, designers, product managers, and founders is broad across stages and industries.

Hiring in Tokyo usually means hiring out of these companies. The biggest names anchor the talent pool — every senior engineer in Tokyo likely has at least one of them on their resume — and the fast-growing ones generate the most movement.

Refolk lets you reach into this pool with plain English. Ask for “senior backend engineers in Tokyowho’ve shipped at scale” or “founders in Tokyowho left in the last year” and Refolk returns a ranked shortlist with the evidence behind each match.
