DIALING RULES

Key Dialing Rules for Japan

Japan's numbering plan requires specific formatting to ensure calls route correctly from Thailand.

Always include the country code

Japan's country code is +81. Whether dialing from your browser or phone, begin with +81 (or 0081).

Drop the leading zero from area codes

When dialing internationally, remove the leading 0 from area codes. Tokyo is 03 domestically; dial 3 when calling from abroad.

Mobile numbers use dedicated prefixes

Japan's mobile numbers typically use prefixes 70, 80, or 90 (e.g., +81 90 XXXX XXXX). Treat these like area codes and dial as-is after the country code.

Call duration is billed per minute

Sayfone charges transparent per-minute rates with no setup fees. Calls are billed in full-minute increments.
