Twitter Japan Releases Email Notification – Asiajin
Contrary to what people think, SMS does exist in Japan. It’s just not used. It never had a real chance, having been buried by e-mail, which became the standard texting communication channel between users on their keitai.
You see, SMS specifications -drafted when bandwidth constraints were high- allow for 140 bytes, that’s 140 8-bit characters for Latin languages, 160 7-bit characters for English, but only 70 16-bit characters for Japanese input, very limiting. Plus, as e-mail was becoming widely adopted, Japanese carriers never bothered looking into interoperability: you still cannot send an SMS from DoCoMo to KDDI -even if that may change, maybe even at the end of this year.
