Japan Release: Controversial Film "Oppenheimer

Oscar best picture winner "Oppenheimer" was finally released in Japan, where its subject -- the man who masterminded the creation of the atomic bomb -- is a highly sensitive and emotional topic.

The US blockbuster hit screens in the United States and many other countries in July at the same time as "Barbie", inspiring a viral phenomenon dubbed "Barbenheimer" by moviegoers.

But while "Barbie" was released in Japan in August, "Oppenheimer" was conspicuously absent from cinemas for months.

No official explanation was offered at the time, fuelling speculation the film was too controversial to be shown in Japan -- the only country to have ever suffered a wartime nuclear attack.

Around 140,000 people died in Hiroshima and 74,000 in Nagasaki when the United States dropped atomic bombs on the cities in August 1945, days before the end of World War II.

At a large cinema in central Tokyo where "Oppenheimer" was showing, there was none of the prominent promotional material that might be expected for a global megahit.

Instead only one small poster advertised the film, which was shot on a $100 million budget and collected nearly $1 billion at box offices worldwide.

The film tells the story of US physicist J. Robert Oppenheimer, who oversaw the bomb's invention.

It drew rave reviews and was the most decorated title at this month's Oscars, scooping seven awards including best director for Christopher Nolan and best actor for star Cillian Murphy.

But in Hiroshima, the city devastated by the first nuclear bomb, the biopic's Academy Awards success met a mixed reaction.

Kyoko Heya, president of the city's international film festival, said after the awards ceremony that she had found Nolan's movie "very America-centric".

Last year, viral "Barbenheimer" memes sparked anger online in Japan, where media reports have highlighted critics who say the film does not show the harm caused by the bombs.
