Number format

How do I write Japan numbers for a bulk SMS list?

Write numbers for Japan in international format: the calling code +81 first, then the national number. If people in Japan dial a domestic trunk prefix such as 0 at the start, leave it out after the calling code. A number written this way looks like +81 90 1234 5678. Spaces and dashes are fine; the console removes them when it reads your list.

Language

Which alphabet do recipients in Japan read?

Most recipients in Japan read Japanese. Text written in Japanese (kana and kanji) is sent in UCS-2, so one SMS segment holds 70 characters (67 per part when split), and a 140-character message costs two segments. Messages in English or other plain Latin text fit 160 characters per segment.

Timing

When is the best time to send SMS to Japan?

Japan keeps one time offset, UTC+9, all year. Local 9:00 to 20:00 in Tokyo is 00:00 to 11:00 UTC in January. The scheduler uses the time zone of your own browser, so convert the local hour you want before you pick it.
