He announced that he is joining Sagan Tosu as a free agent after leaving Atletico Madrid last month.
His contract expired at the end of the 2017-18 season and he will continue his career in Asia, following in the footsteps of Barcelona legend Iniesta.
Torres scored 10 goals in his final season at Atletico, including netting twice against Eibar in his final ever La Liga appearance .
At his grand Sagan unveiling on Tuesday morning, Torres held aloft a scarf which, according to our favourite J-League shaman, journalist Dan Orlowitz, read "This isn't a false report!" - a reference to the premature announcement of the transfer posted (then hastily deleted and apologised for) on the league's official website back in May.
The 34-year-old becomes the second high-profile arrival in Japan in recent times, after his compatriot Andres Iniesta agreed to move to Vissel Kobe earlier in the summer, where he will link up with another famous name in Germany's Lukas Podolski.
Torres, 34, left boyhood club Atletico Madrid at the end of the season following the expiration of his contract and made a decision to depart Europe despite several offers to stay within the continent.
"I think that Japan and the Japanese league is going to be a great experience".
The World Cup victor had been linked with moves to the A-League and MLS but - like Iniesta at Vissel Kobe - the next stage of his career will be in Japan.
Capped over 100 times by Spain, Torres was also in La Roja's squad as they won the European Championship in 2008 and 2012, and also featured in the 2010 World Cup-winning squad.
