FAQ
- Is the japanese random username generator data real?
- No. Every value is synthetic, generated with @faker-js/faker. There is no real personal data, so it is safe for testing, demos and committing to a repo (GDPR-friendly).
- How is this different from the default random username generator?
- Names, addresses, phone numbers and other locale-specific fields are generated using Japanese (ja) data, so they look native to that region instead of US English.
- How do I get this data in my code?
- Call the free API: GET https://mock.wrapper-agency.com/api/v1/mock?type=username&count=25&locale=ja. It returns a JSON array of Japanese records. Use ?seed=123 for deterministic output.
