Japan are poised to begin the defence of their World Wheelchair Rugby Championship title in Vejle in Denmark.

The competition is fierce, with Paralympic champions Britain looking to claim their first world title and four-time gold medallists the United States prepped to reclaim the trophy.

Australia, the runners-up from four years ago, and 2014 silver medallists Canada are also tipped to be in contention.

Canada, in particular, are entering the tournament on a high after beating Britain in the final of the Wheelchair Rugby Quad Nations.

France - the bronze medallists - will have hopes of repeating or even furthering their success.

Group A consists of Britain, the US, France, New Zealand, Germany and Switzerland, while Group B is made up of Australia, Japan, Canada, Denmark, Brazil and Colombia.

Princess Benedikte of Denmark is anticipated to attend the Opening Ceremony, which is due to be staged prior to competition starting tomorrow at the DGI Huset recreational centre.

Denmark face Brazil in the first contest, with Britain against Switzerland following.

Japan are scheduled to get their defence completely underway on Tuesday (October 11) and the group stage is running until Friday (October 14).

The medal matches are set to be held on October 16.

"On the court, it will be an exciting Championship, where more teams than ever can come out on top," John Petersson, the President of Parasport Denmark, said.

"In the past, powerful nations such as Australia, the USA, Japan, and Canada have sat firmly at the top of international wheelchair rugby.

"Still, in recent years European teams such as Great Britain, France, and Denmark have been able to match them.

"Hopefully, an enthusiastic home crowd can give the Danish national team the extra powers.

"In any case, I dare to promise that it will be both enjoyable and exciting."
