Scotland has destroyed Rugby World Cup giantkillers Japan 45-10 in Gloucester, with Mark Bennett scoring two tries and captain Greig Laidlaw kicking 20 points.

Japan's heroics in the 34-32 win over South Africa left them exhausted and after a bright start with a brilliant Amanaki Mafi try, they just could not keep up with the dark blues.
Scotland win their first game, while Japan now have one win and one loss.
Leading 12-7 at half-time, Scotland took complete control after the break.
Two tries by Bennett, and one each from flanker John Hardie, Tommy Seymour and Finn Russell on his 23rd birthday, crushed the spirited Japanese.
Scottish skipper Laidlaw gave a clinical display of kicking on his Gloucester home ground, which was packed with 14,354 people for the occasion.
The Scots did not make the same error as Springboks skipper Jean de Villiers, as Laidlaw opted to go for goal with their first penalty, rather than kick for touch.
The Scottish captain slotted over for a 3-0 lead after two minutes and soon added a second.
Japan stayed true to their attacking instinct. Star fullback Ayumu Goromaru kicked right into the corner from a penalty and No 8 Amanaki Mafi drove over for a brilliant try from the throw-in to get Japan back into the game.
Goromaru, who scored 24 points against the Spingboks, added the conversion for a short-lived 7-6 lead, but Laidlaw added two further penalties to take it out to 12-7 as Japan repeatedly got on the wrong side of Irish referee John Lacey.
Lacey's patience ran out after persistent infringements and he flashed a yellow card in the 23rd minute at Japanese wing Kotaro Matsushima for ripping the ball from Scottish opposite number Sean Lamont after a tackle.
Laidlaw missed the resulting penalty and - despite being one man down - the Japanese kept the Scots largely inside their own half.
They might even have reduced the deficit.
Goromaru sent a penalty just wide of a post and Mafi looked to be due his second try but the 25-year-old Tongan-born back-row forward was judged to have taken the ball from a forward pass.
Maft then tried a novel way of going over the tryline by leaping NFL style over the massed bodies, but came up short.
Goromaru produced a heroic tackle on the stroke of half time to stop Tommy Seymour scoring a near certain try.
The Japanese came bursting out of the blocks in the second-half, with Mafi bullocking his way deep into the Scots' 22 before being brought to ground and he had to be stretchered off with a leg injury.
Goromaru kicked a penalty - the Scots having gone offside - to move the Japanese to within two of the Scots at 12-10.
However, Hardie stretched the lead as, fed by Laidlaw, he went over after a rare fluent backline movement, which saw Matt Scott held up just short of the line. It was Scotland's first World Cup try since their first match of the 2011 tournament against Romania.
It was game over just after the hour mark, as Seymour this time made no mistake, intercepting a Japanese pass inside the Scots 22. He just had the legs to evade a couple of Japanese defenders to touch down - Laidlaw converted for 31-10.
Somewhat undeservedly from a Japanese point of view the game turned into a rout as their weary bodies failed to stop Bennett going over for his second try, with Laidlaw adding the conversion.
