Japan's Algeria survivors, dead arrive in Tokyo

Anxious relatives awaited those who made it out of the In Amenas complex alive, amid a renewed national awareness of the perils of doing business in resource-rich, but unstable parts of the world.

The government-owned plane with its red sun livery touched down at Haneda Airport shortly before 7:00 am (2200 GMT Thursday) in warm winter sunshine.

Airport officials used black umbrellas to shield those getting off the plane from the glare of cameras, feeding the blanket media coverage in a country baffled by what happened half a world away.

Foreign Minister Fumio Kishida stood alongside officials from engineering firm JGC, which employed -- directly or indirectly -- all Japanese caught up in the siege, to bow deeply after what appeared to be coffins were brought out from the plane's cargo hold.

Three cargo trailers, each apparently with three coffins, lined up near the plane's tail as the assembled dignitaries laid on them bouquets of white flowers, a common offering for the deceased in Japan.

Tokyo on Thursday said it had now accounted for all ten men who had been out of contact since Islamist gunmen stormed the desert gas plant over a week ago.

Dozens of foreigners were killed during a four-day standoff that ended in a bloody showdown with Algerian commandos on Saturday, with reports of summary executions.

Japan's body count of 10 is the highest of any nation whose citizens were caught up in the crisis in the Sahara and an unusual taste of Jihadist anger for a country that has remained far from US-led wars in the Muslim world.

As the aircraft left north Africa, mourners had paid their respects to lost colleagues at a makeshift altar at the headquarters of plant-builder JGC, which employed -- directly or indirectly -- all the Japanese who died.

A steady stream of visitors dressed in black solemnly bowed to a Buddhist cenotaph, as they urged departed souls to find peace.

An elegantly handwritten prayer for those who lost their lives was inscribed on a wooden tablet, around which lay bouquets of white flowers.

The loss of so many colleagues is a heavy blow to JGC in a country where corporate communities are close-knit and company loyalties remain strong.

Media reported Thursday that the tenth Japanese victim of the Islamist gunmen's rampage was Tadanori Aratani, 66, a former vice president of JGC and lately its supreme adviser.

The government said it would be officially revealing the names of all those who died, many of whom have been identified by media already with newspapers and broadcasters telling heart-wrenching tales of never-to-be-realised plans for family celebrations.

Broadcaster NHK spoke to the sobbing elderly mother of one man struggling to come to terms with the loss of her son less than two years after the March 2011 tsunami swept her husband to his death.
