"I am concluding my career in the national team", the former AC Milan man said.
However, the effect of his exit will be lessened once the Saints round-off negotiations to sign FC Basel forward Mohamed Elyounoussi, as the club near a £16 million deal, according to Sky Sports.
Although he refused to criticise Neymar directly, Mexico manager Juan Carlos Osorio was unimpressed with the behaviour of the Brazil players and blamed their theatrics for halting his side's rhythm. At one stage of the match, it looked like Japan would make it to the Quarterfinals for the first time in history, but after Belgium scored a goal in the dying minutes of the match, Japanese fans were heartbroken.
"It hurts, but it was a really good game and I feel moved".
The Samurai Blue of Japan were eliminated from World Cup play on Monday.
While the loss ended Japan's otherwise memorable run in the tournament, the team and its supporters continued to display tremendous sportsmanship that amazed sports fans around the world.
I want to go through the quarter-final, semi-final and maybe the final.
"We'll see tomorrow", Hazard said on Sunday, when asked if the long break would disrupt the players.
"This is our third time in the last 16 and we have been very tactical in our approach", Nishino said.
Interestingly, the Samba Boys have not been prolific in attack yet boast one of the stingiest defences at this year's World Cup.
The victor of that tie will go on to face the victor of Monday's other game, which sees Belgium meet Japan in Rostov-on-Don (1800 GMT). A host of key players were rested for the 1-0 victory against England, including Hazard, Lukaku and Kevin De Bruyne, but they will return here. "We know we have quality and collectiveness to beat them, but we also know that it will not be easy".
And Hazard, who has also played a starring role for the Red Devils in Russian Federation, has been praising Lukaku for his development into a top-class striker.
