Ono targets World Cup place
The 2002 Asian player of the year signed a two-year deal with Shimizu S-Pulse after an injury plagued two years with Bundesliga side Bochum.
"It will be impossible unless I can play seriously for Shimizu in every game," the 30-year-old midfielder told Japanese media on Friday.
"I just want to go ahead to realise my dream."
Ono has played in the previous three World Cups but his last international appearance came in August 2008.
