Best Time to Call Japan

Recommended Calling Hours

• For consumers, avoid calls before 09:00 and after 20:00 local time, and avoid Sundays and national holidays for sales calls.
• For business contacts, standard hours are roughly 09:00 to 18:00 on weekdays; avoid lunchtime around 12:00 to 13:00.

Calling Etiquette in Japan

• Open with a polite greeting and your name/company; for business, confirm you are calling the right person and if it is a good time.
• Use family name plus san (e.g., Tanaka san) in professional contexts unless invited to use given names.
• Be concise and structured; state purpose early, avoid aggressive sales tactics, and allow the other party to decline.
• Silence while listening is normal; avoid interrupting and confirm understanding briefly.

Reaching Japan via Apps

• LINE is the dominant messaging and calling app; many people prefer it over voice calls from unknown numbers.
• WhatsApp, Skype, FaceTime, and other VoIP apps are available but less universal than LINE for local contacts.
• Corporate users may rely more on Microsoft Teams, Zoom, or similar tools for scheduled business calls.

International Calling Requirements in China

• Ensure your SIM is real-name registered; unregistered SIMs may be blocked from IDD and roaming
• Enable international calling (IDD) with your carrier; many plans have IDD disabled by default
• Maintain sufficient prepaid balance or an active postpaid plan; IDD calls are usually charged at premium rates
• Dial 00 or use + before the destination country code, then area or mobile code and number
• Business or call center users may need additional registration for high-volume international traffic

Troubleshooting Calls to Japan

Call cannot be completed as dialed - Check you used 00 or +, then the correct country code and removed any leading 0 from the local number
International calling not enabled - Contact your carrier to activate IDD service or switch to a plan that includes international calling
Roaming not allowed - Before travel, enable roaming and purchase a roaming package; restart your phone after activation
