The BBC's Rupert Wingfield-Hayes in Tokyo says the Izumo is the pride of the Japanese navy, and is by far its biggest ship. The 249m-long Izumo can carry up to nine helicopters, and resembles US amphibious assault carriers, reported the Japan Times.

Under Prime Minister Shinzo Abe, Japan is gradually pushing the limits of what its modern and powerful military is allowed to do, and with tensions high on the Korean peninsula, Mr Abe appears keen to try out the new laws for the first time, our correspondent says.
Japan's post-World War Two constitution bars its military from using force to resolve conflicts except in cases of self-defence.Japan's post-World War Two constitution bars its military from using force to resolve conflicts except in cases of self-defence.
The Izumo is the first warship deployed outside of military exercises under new laws passed in 2015 that allow Japan to come to the aid of an ally under attack known as "collective self-defence". Analysis by Rupert Wingfield-Hayes, BBC News, Tokyo
Mr Abe's government, which pushed for the change, faced criticism that the new laws could lead the country into unnecessary wars abroad - something Mr Abe has rejected. Pacifist Japan has one of the most powerful militaries in the world, with a navy bigger and more modern than the British Royal Navy.
Tokyo could have sent a much smaller destroyer to escort the US Navy's Richard E Byrd. But sending the 27,000-tonne Izumo was perhaps too good an opportunity for Prime Minister Shinzo Abe and his Defence Minister Tomomi Inada to waste.
Both Mr Abe and Ms Inada are right-wing nationalists who want to scrap Japan's pacifist constitution. That is all but impossible. So instead, last year, Mr Abe succeeded in pushing a new security law through parliament.
In effect the new law ignores the constitution, and says Japan's forces can come to the defence of its allies. Mr Abe knows there is widespread public opposition to "remilitarising" Japan. So in that context, the growing threat from North Korea is useful to him.
