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 Germany

• Ensure your mobile or fixed line plan includes international calling; many basic tariffs block IDD by default
• Dial 00 or use + on mobiles, then country code, area or mobile code, and subscriber number
• Some providers require enabling international or premium destinations via customer portal or support
• Prepaid SIMs may need sufficient balance and sometimes an initial ID check before IDD is allowed
• For cheaper IDD from landlines, optional carrier selection prefixes (010xx) can be used before 00

Troubleshooting Calls to Japan

Call cannot be completed as dialed or fast busy tone when calling abroad - Check you used 00 or +, removed the foreign trunk 0, and that international calling is enabled on your line
Announcement that the number is not reachable or blocked - Verify the destination number format and that your plan allows calls to that country or range
High unexpected charges on bill after international calls - Review your tariff, consider adding an international option, or use VOIP or 010xx discount providers
