## FAQ

### How many companies use Microsoft Windows in Japan?

473 companies in Japan have job postings that show they use Microsoft Windows, as of 25 Sep 2026. 12 are confirmed and 461 are likely.

### How does JobsPipe know a company uses Microsoft Windows?

From the company's own job postings. Each posting is read for the technologies it names, and every company and technology pair is graded: confirmed when two independent checks agree on Microsoft Windows in at least one posting, likely when it is a stated requirement or appears in two separate postings. A single passing mention is not counted here. It is evidence of a team working with Microsoft Windows, not a purchase record.
