nding Japanese Phone Numbers: A Complete Guide

If you're planning a trip to Japan or need to contact someone there, understanding how Japanese phone numbers work is essential. The Japanese phone number system may seem complex at first, but it's quite logical once you understand the basics. This comprehensive guide will answer common questions about Japanese phone numbers and provide all the information you need to make calls confidently.

What is the format of Japanese phone numbers?

Japanese phone numbers typically consist of three main parts:

1. Country code (+81)
2. Area code (1-5 digits)
3. Local number (remaining digits)

The total length of a Japanese phone number, including the country code, is usually between 11-12 digits.

What is Japan's country code?

Japan's country code is +81. When calling Japan from abroad, you'll need to dial this code before the rest of the number. If you're already in Japan, you don't need to use the country code for domestic calls.

How do area codes work in Japan?

Area codes in Japan, known as "shigai-kyokuban" (市外局番) in Japanese, indicate the geographic region of the phone number. Larger cities tend to have shorter area codes, while smaller towns have longer ones. For example:

• Tokyo: 03
• Osaka: 06
• Yokohama: 045
• Sapporo: 011

When calling within Japan, you need to dial a "0" before the area code. However, when calling from abroad, you omit this "0" and use the country code instead.
