They will be among 12 teams, including Afghanistan, Mozambique, Germany, the United States and Vanuatu taking part in the International Cricket Council World League Division Five which runs from May 23 to 31.
The ultimate goal is a place in three years' time at the World Cup in India, Pakistan, Sri Lanka and Bangladesh.
Tournament finalists in Jersey, a British-ruled island nearer France than the UK mainland, will be promoted to Division Four.
There they will join Hong Kong, Fiji, Tanzania and Italy in a six-team event that will take place in the Tanzanian capital of Dar-Es-Salaam from October 4 to 11.
In turn, the top two teams there will progress to Division Three in Argentina in January.
They will then go to the United Arab Emirates for next year's World Cup qualifier, which incorporates Divisions One and Two.
At the end of that tournament the top four teams from beyond the elite will join the 10 full, Test, members of the ICC (England, Australia, South Africa, New Zealand, West Indies, India, Pakistan, Sri Lanka, Zimbabwe and Bangladesh) to decide the world's best one-day international side.
Japan team manager Jarrad Shearer said cricket in the country would get a huge boost from doing well in Jersey.
"The biggest problem cricket in Japan faces is lack of exposure," he said in an ICC statement. "The average person just doesn't know what cricket is. That's why tournaments like this are so important.
"Our goal for this tournament is, first and foremost, to win it and progress to Division Four."
But Shearer admitted that wouldn't be easy.
"Preparation has been difficult as our season doesn't start here until April so very few of the players have had any club matches.
"Nonetheless, we started pre-season in January. As winters here are quite cold, much of our training has been indoors at a tennis centre."
He added: "We also played two games at the beginning of May against Melbourne Cricket Club, whose players included an ex-Test cricketer and a current New South Wales representative.
"Those games were excellent practice and we won the second game."
And he insisted there were Japan players who could make an impact in Jersey.
"Our number three batsman Masaomi Kobayashi is definitely a player to watch. He hits the ball hard and has a tremendous eye, which gives him a lot of time to play his shots.
"We expect he will score a lot of runs and give most teams grief."
"Our wicket-keeper and opening batsman Tatsuro Chino is also a tremendous prospect," Shearer added.
"He has great hands behind the wicket. He didn't drop a catch or let a single bye through at the ICC East Asia-Pacific tournament in Auckland last year."
