TOKYO (Reuters) - A 44-year-old Japanese freelance journalist returned home on Thursday to rice balls cooked by his mother but an uncertain future more than three years after militants in Syria captured him in what he described as a physical and mental “hell”.

Jumpei Yasuda, who quit his job as a reporter on a Japanese newspaper to cover the Iraq war in 2003, arrived in Tokyo from Turkey, rekindling debate in Japan about reporting from war zones that some see as reckless adventurism and others as courageous journalism.

Television footage showed a gaunt-looking Yasuda walking down stairs to a waiting car at Narita airport for a short ride to another airport building.

To reporters’ calls of “Welcome home” he simply nodded with a strained smile as he disappeared down a corridor to where his family waited.

Later, his wife, a singer known as Myu, bowed deeply and apologized to a packed news conference at which Yasuda did not appear.

“He would like to apologize for causing a fuss and making people worry about him, but fortunately he was able to safely return to Japan,” she said, sniffing back tears.

“He feels he has a responsibility to explain things to you as much as possible,” she added, but said this would have to wait until he had undergone medical checks.

Yasuda gave few details of his captivity but told his parents, who were also there, that he had worried they might not be alive, Myu said, adding that he ate some rice balls his mother had made for him “very happily”.

“He also said he wants to take a hot bath and then sleep in a futon.”

SYRIAN CAPTURE NOT FIRST TIME

Yasuda traveled to Iraq in late 2002 using paid leave from his regional newspaper job but was frustrated when they refused to send him on assignment there and quit in 2003. In 2004, on another trip to Iraq, he was captured near Baghdad by militants, who held him for three days.

In a book he published the same year, he explained he had undertaken the assignment because he wanted to show the suffering caused by the war.

“I could not see faces of people living in the country which was called part of an ‘axis of evil’ from any information provided by Japanese media, which only reported diplomatic matters and inspections by the United Nations,” he wrote.

Yasuda returned to Iraq in 2007 to work as a cook at an Iraqi army training camp and in 2010 published a book in Japan about war zone laborers.

His last trip to the region was in 2015. Apart from a few brief videos released by his captors, little is known about what happened to him after he disappeared. Other Japanese captured there have been killed.

In 2015 veteran Japanese war correspondent Kenji Goto and a friend he had tried to free, Haruna Yukawa, were beheaded by Islamic State militants. Both were lambasted in Japan for their decision to travel to Iraq.

Earlier, in 2004, a Japanese high school graduate, an aid worker and a freelance photographer taken hostage in Iraq were also condemned as irresponsible after their release. Japan is careful to stay out of disputes in the Middle East and tries to maintain friendly ties with countries such as Iran and Saudi Arabia that are at loggerheads.

“There was bashing before and it appears it is already happening this time,” freelance journalist Kosuke Tsuneoka, a friend of Yasuda, told Reuters in a telephone interview. “Yasuda is tough and has great mental strength. I’m not worried he will be hurt.”

As Yasuda flew to Japan, some on social media were already condemning him.

“After he returns, I want him to hold a news conference to apologize and work to pay back the ransom. I don’t need to hear his opinion,” tweeted a person with the twitter handle “kawako”.

The Japanese government has denied paying a ransom for Yasuda’s release.

Yasuda’s wife said he must be allowed time to recover, and Yasuda himself - apparently struggling to speak Japanese - told Reuters en route to Istanbul his future was uncertain.

“I am happy that I can return to Japan. At the same time, I don’t know what will happen from here or what I should do,” he said.
