Developer tools / infra Creators in Japan: 20 Indexed

This page slices by audience function, not content topic: 20 creators in Japan whose audience is Developer tools / infra.

Why function matters: two creators can both post Software content while one reaches Developer tools / infra and the other reaches casual viewers. Conversion differs enormously — and that difference is invisible in follower count, views, or even topic.

How this slice differs from the index as a whole

• X (Twitter) alone accounts for 45% here, against 9% index-wide — a skew specific to this slice, so budgeting from index-wide platform habits will misallocate.
• 70% have recent content captured for judgement versus 46% overall — better-evidenced than average.
• Average authenticity is 49/100 against 56/100 index-wide — worth raising your authenticity floor before shortlisting.

Platform split

How to read these numbers: this covers creators indexed and validated inside Koinon Link, not every creator on the platform. Suspected bought-follower accounts are quarantined and excluded from the table above (shown separately). The authenticity score is our own anomaly detection over follower/engagement structure, not a platform-official metric. Figures update as collection continues.

Ordered by follower tier, first 10 shown. Each link opens that creator’s public profile: what they post about, who reads it, and recent samples — no contact details.

How the function is determined

Not from what the creator calls themselves, but from reading their content: we pull up to 100 recent posts and derive who the content speaks to and what job those people do. When content is too sparse or scattered we mark it undetermined rather than inventing a tidy answer.

That is also why this page shows far fewer creators than "Software creators in Japan" overall — only creators whose content we have analysed appear here.
