Best Fitness & Wellness Tech Companies in Japan
The 59 best Fitness & Wellness Tech companies in Japan in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: hacomono.
Wondering which Fitness & Wellness Tech companies in Japan are actually pulling funding? This directory ranks 59 of them by disclosed equity and recent momentum, and the numbers tell a real story.
Hacomono leads the pack at $29M raised, with ACCELStars at $7M and SoxAI at $6M rounding out the top tier. Total disclosed funding across the cohort sits at $89M, no unicorns yet, but the install curve is bending hard. Median app installs across health and fitness categories are up roughly 15% YoY across 1,361 tracked apps, a trajectory that signals genuine consumer pull, not just hype. I find that stat particularly telling for a market still in early consolidation. Investors like Chiba Dojo, Beyond Next Ventures, and DG Daiwa Ventures are circling this space for a reason. So if you're mapping where capital is quietly accumulating before the breakout names become obvious, Japan's Fitness & Wellness Tech cohort is exactly where to start looking.
