Japan unveiled on Friday a set of measures to safeguard the 1.2 million or so Japanese living abroad, including a big increase in security guards and cameras at 88 overseas schools catering to Japanese students.

In the wake of the Islamic State hostage crisis, which cost the lives of two Japanese men, the government will also start sending expatriates urgent bulletins about terrorism and other contingencies, as well as inquiries about their safety, via a cellphone text messaging service, the Foreign Ministry said.

Speaking at a news conference, Parliamentary Vice Foreign Minister Kazuyuki Nakane said the government will strengthen safety measures at schools for Japanese students soon after receiving specific requests from each of them.
