Numbers that start with 0120, 0800 or 0570

0120 and 0800 numbers are free inside Japan and often can't be reached from abroad. 0570 Navi Dial numbers usually can't either. Companies that serve customers abroad list a regular number, such as docomo's Tokyo number above.

When to call

Japan has one time zone, Japan Standard Time (UTC+9). The cards below show your time and the time in Tokyo.

Japan does not change its clocks, so the time difference only shifts when your own country changes.

Call quality

A browser call needs a steady connection more than a fast one, using roughly half a megabyte to one megabyte of data per minute (an estimate).

• Use Wi-Fi or a good mobile signal.
• Use headphones to avoid echo.
• Switch off a VPN if the audio is choppy or one-way.
• Check the microphone permission if the other person can't hear you.
