A local writes 090 1234 5678 — the dialer below turns that into what you press.

Japan's international prefix is 010 rather than 00, one of the few plans to differ. Domestic numbers hide behind a trunk zero, so 090 1234 5678 becomes +81 90 1234 5678. Mobiles take 070, 080 and 090, while Tokyo's landlines sit under 03. All lengths are fixed, so miscounts stand out fast.

Mobiles are eleven digits beginning 090, 080 or 070; landlines pair an area code starting 0 with the balance of ten digits.
