How to read these numbers responsibly.
What is included?
4,146 live employer job pages explicitly located in Tokyo or a named Tokyo ward/neighborhood. Duplicate IDs and expired listings are removed; 411 Japan-wide or non-Tokyo listings are excluded.
How is demand measured?
A skill counts when the posting's structured vector is at least 70% confident. This includes explicit requests and strong deterministic implications such as React implying JavaScript.
How are salaries calculated?
Only valid ranges with both a minimum and maximum are used. We take each range midpoint, then calculate the median or mean across jobs. The complete-range coverage is 32%.
What does “now” mean?
The current snapshot refreshes after the job crawl. Daily aggregate snapshots are retained, and trend comparisons appear after 14 comparable days. Skill, language and visa-support fields are AI-assisted estimates; verify details on the employer's original posting.
