Frequently Asked Questions
What format do the generated Japan phone numbers use?
All phone numbers follow Japanese standard formats: Mobile numbers use 0X0-XXXX-XXXX format, landline numbers use area code + local number format with hyphens. We also provide international format with +81 country code and raw number format for different use cases.
Are the generated Japan phone numbers real?
No, these are algorithmically generated test numbers. We follow Japanese formatting rules and use valid number ranges, but do not assign real phone services.

We use number ranges from major Japanese cities including Tokyo (03), Osaka (06), Nagoya (052), Sapporo (011), Fukuoka (092), Kyoto (075), and many other major urban areas.
Can I specify a particular Japanese city for landline numbers?
Currently, the generator randomly selects from major Japanese cities. Future versions may include city-specific generation options.
