- Domestic long-distance calls (from other parts of Japan): Dial 0-1548-XX-XXXX. The leading '0' is the trunk prefix, followed by the area code and the subscriber number.
- International calls (from outside Japan): Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), then Japan's country code 81, then the area code without the leading '0' (1548), and finally the subscriber number. For example, +81 1548 XX XXXX.
Overlay and Numbering Considerations

Caller Instructions
For local callers within Teshikaga, simply dial the 6-digit number. For callers from other regions in Japan, always include the trunk prefix '0' and the area code '1548'. For international callers, remember to drop the leading '0' and use the +81 country code. Be mindful of time zone differences; Japan Standard Time (UTC+9) applies throughout the country.
