Munroe has 22 wins from 23 professional fights
Leicester super-bantamweight Rendall Munroe will fight WBC champion Toshiaki Nishioka in Tokyo on 24 October.
Munroe, 30, will take eight weeks off from his day job as a binman to prepare for the biggest fight of his life.
Nishioka, 33, has held the title since January 2009, making three defences, but has lost four of his 43 fights in a record that includes three draws.
"This is a big opportunity. It makes no difference to me if the fight's in Japan," said Munroe.
Munroe has just the one loss from his 23 fights with eight of his victories ending inside the scheduled distance.
I enjoy what I'm doing but if they tell me I can't have the time off to train I'll have to leave
He last fought in April, stopping Mexican Victor Terrazas in the ninth round, and insists he is undaunted by the prospect of facing Nishioka in Tokyo.
"To be a world champion you have to fight world-class fighters in world-class places," said Munroe. "This is a chance for me to show I'm good enough to be thought of as world class."
The southpaw, promoter Frank Maloney, manager Mike Shinfield and trainer Jason Shinfield will spend 12 days in Tokyo before the fight, with Maloney explaining: "Tokyo is about eight hours ahead so we need to be there well in advance to make sure everything is spot on.
"People are writing Rendall off, but there are far more hostile places than Japan for a fighter to travel to.
"Nishioka's camp have been complete professionals to deal with and I am sure Rendall will get a fair deal if the fight goes 12 rounds."
Munroe, who trains in Derby, had feared he might not be given the time off work needed to prepare for his clash with Nishioka, who is a national hero in Japan.
"Normally work are OK but for my last fight they were getting a bit funny about taking time off," said Munroe recently.
"I enjoy my job. Effectively I'm training at work because I'm running around all day emptying bins.
"I'm outside mixing with the people and it keeps my feet on the ground. I've got a family and two kids so the job is a little provider.
"I want to stay at work and as soon as I win the fight I'll go straight back to it."
