Top 16 Running Influencers in Japan on Instagram (Aug 2026)

Three approaches work. You can search local hashtags and location tags manually, which is free but slow and biased toward whoever posts most. You can ask your existing customers who they follow. Or you can filter an index: Leewou holds 19 running influencers in Japan and lets you narrow by follower range, engagement rate, audience country and suspicious-follower share in one query. The 16 on this page are the top of that set, and the rest are in the app.

On this ranking, Nozomi Tanaka 田中希実【公式】 (@nozomi_tanaka_official), ウルトラランナーみゃこ｜Ultra Runner Myaco (@myaco_run), Yuma Hattori 服部勇馬 (@hattori.1113). The ordering blends engagement rate, audience quality and reach rather than follower count alone, which is why a smaller account can outrank a larger one. Data was last refreshed in Aug 2026.

Use the set you are actually buying from as the benchmark, not a global average. Across these running influencers in Japan, the median engagement rate is 4.91% at a median of 14.4K followers. Anything meaningfully above that median is doing better than its peers at the same size; anything well below is worth a second look before you pay for reach.

Not entirely, and that is true of every Instagram list. Across this group, an average of 18.6% of followers show signs of being fake or inactive. We publish that figure on every card instead of hiding it, so you can discount reach estimates before you negotiate. Anything above 30% is worth auditing manually before you commit budget.

Not on this page: it is a public preview. Inside Leewou you get the full audience breakdown (age, gender, country, city, interests, credibility), historical growth, content performance and email unlocks, plus the ability to save creators to shared lists and monitor their campaign posts. The trial runs 14 days with no card required.
