Japanese Prime Minister Shinzo Abe on Sunday condemned the apparent killing of journalist Kenji Goto by Islamic State, vowing to work with other nations to bring those responsible to justice.
"I feel strong indignation at this inhumane and contemptible act of terrorism," a grim-faced Abe said in brief remarks to reporters. "I will never forgive these terrorists."
"Japan will work with the international community to bring those responsible for this crime to justice," he said, reiterating that Japan would not give in to terrorism.
Islamic State militants said on Saturday they had killed Japanese hostage Kenji Goto, after the apparent failure of sustained international efforts to secure his release through a prisoner swap.
The hardline Islamist group, an offshoot of al Qaeda which controls large parts of Syria and Iraq, released a video which purported to show the beheaded body of journalist Goto and threatened further attacks on Japanese targets.
Islamic State has said Goto was held along with a Jordanian pilot. Efforts to win their release had focused on the possible release of an Iraqi would-be suicide bomber jailed in Jordan 10 years ago. The video did not mention the pilot.
Japan condemned the militants and said Prime Minister Shinzo Abe's cabinet would meet in response to the video, which showed a hooded man standing over Goto with a knife to his throat, followed by footage of a head put on the back of a human body.
The release of the video came exactly a week after footage purportedly showing the beheaded body of another Japanese hostage Haruna Yukawa.
"I cannot help feeling strong indignation that an inhuman and despicable act of terrorism like this has been committed again," Chief Cabinet Secretary Yoshihide Suga said, adding the video appeared to show Goto. "We resolutely condemn this."
A grim-faced Abe told reporters Japan would not give in to terrorism and said his country would work with international partners to bring those responsible for Goto's apparent killing to justice.
A White House spokeswoman said the United States was working to confirm the authenticity of the latest video and "strongly condemns" the militant group's actions.
The Islamic State threats to kill their Japanese hostages came after Abe announced $200 million in non-military aid for countries contending with Islamic State. His government has rejected any suggestion it acted rashly and stressed the assistance was humanitarian.
Addressing Abe, the militant in the video said: "Because of your reckless decision to take part in an unwinnable war, this knife will not only slaughter Kenji, but will also carry on and cause carnage wherever your people are found. So let the nightmare for Japan begin."
The militant had the same British accent as the man featured in previous Islamic State videos showing beheadings. Goto wore an orange jumpsuit like Islamic State captives in past footage.
The landscape in the video showed a hill and land covered in scrub, and appeared different to the desert setting of previous videos.
Islamic State, which has seized large swaths of Iraq and Syria, has beheaded a number of Western journalists and aid workers, saying they were paying the price for their governments' fight against the group.
It has also killed many local people, through beheadings, stonings and shootings, accusing them of violating their hardline interpretation of Islamic law.
In November the Syrian Observatory for Human Rights monitoring group said Islamic State had killed 1,432 Syrians off the battlefield since the end of June when it declared a caliphate in the territory under its control.
There was no mention in the one-minute video of Jordanian pilot Muath al-Kasaesbeh who was seized by Islamic State after his jet crashed in northeast Syria in December during a bombing mission against the militants.
An audio message purportedly from Goto earlier this week said Kasaesbeh would be killed if Jordan did not free Iraqi Sajida al-Rishawi, in jail for her role in a 2005 suicide bomb attack that killed 60 people in the Jordanian capital Amman.
Abe's government had put high priority on seeking the release of Goto, a veteran war correspondent captured by the militants in late October when he went to Syria seeking Yukawa's release.

'Islamic State video of Goto killing appears genuine'
The video purporting to show the beheading of Japanese journalist Kenji Goto by Islamic State militants appears genuine, Defense Minister Gen Nakatani said on Sunday.
Tokyo's Metropolitan Police Department reported to a meeting of ministers from Prime Minister Shinzo Abe's government that the video "has a high degree of credibility," Nakatani told reporters.
