Wales star Liam Williams leaves Cardiff for Japan's Kubota Spears

The 32-year-old had a year remaining on his contract, but Cardiff, along with the other three Welsh regions, are facing a difficult economic climate. Jarrod Evans and Dillon Lewis left the club to join English club Harlequins in April.

"I'm delighted to announce that I have signed with Kubota Spears for next season," Williams, who has been capped 84 times by Wales, wrote on his Twitter account on Wednesday.

"I have fond memories of playing in Japan in the 2019 World Cup. I will never forget how welcoming everybody was. I am looking forward to experiencing a new way of life with my wife Sophie and we are excited about the opportunity.

"I have made some incredible memories in Welsh rugby over the years and must thank the @welshrugbyunion and @cardiffrugby for their understanding in what has been a challenging few months.

"I will be doing everything possible to be selected for the World Cup campaign with @welshrugbyunion and am excited about the opportunity to be involved."

The Rugby World Cup is being hosted by France and runs from September 8th to October 28th.
