Paraguay beat J. League first division side Jubilo Iwata 3-1 in a World Cup warm-up friendly in Japan on Tuesday, while Costa Rica fell 2-0 to Nagoya Grampus Eight.
At Paraguay's training base in Matsumoto, Nagano Prefecture, Roque Santa Cruz, Jose Cardozo and Nelson Cuevas were on target as the South Americans brushed aside an Iwata side missing three players called up to Japan's World Cup squad.
In Toyota, Aichi Prefecture, Brazilian Ueslei and Ryuta Hara scored second-half goals in a game that marked the return of Costa Rica's Manchester City striker Paulo Wanchope from a five-month layoff forced by a knee injury.
