PM Abe's approval ratings rise in Japan after hostage crisis

Japan's biggest daily Yomiuri found that support for Abe's government had risen to 58 percent from 53 percent in January. The paper surveyed 1,054 people by telephone on Friday and Saturday for the poll, which was the first since the hostages were killed.

A separate poll released by Kyodo on Saturday also showed an increase in support for Abe. More than 60 percent of respondents said they approved of the government's response to the hostage crisis.

Islamic State militants beheaded journalist Kenji Goto last month, a week after the group released footage appearing to show the beheaded body of another Japanese hostage, Haruna Yukawa.

Abe has vowed to step up humanitarian aid to the militant group's opponents in the Middle East and bring the killers to justice. The gruesome executions and the recordings of Goto released by the militant group captured the attention of the pacifist nation.

A majority of the Japanese surveyed by both Yomiuri and Kyodo agreed with Japan's plan to continue humanitarian aid to regions affected by the Islamic State.

In terms of how Japan should respond to the Islamic State threat, 57 percent of people polled by Kyodo said any response should be non-military.

Abe's popularity had slipped in more recent polls after the resignations of key cabinet ministers and due to Japan's floundering economy, though his party won a landslide snap election in December.

The killings of the hostages have fanned calls to allow Japan's long-constrained military to conduct overseas rescue missions as part of Abe's push for a more muscular security posture.
