Japan head coach Takeshi Okada praised his players following a lacklustre 1-0 victory against Cameroon in Group E of the World Cup in Bloemfontein.
Okada, who predicted a single goal victory the day before the match, said it was only one step towards qualification as focus immediately turned to his side's next game against Holland - who had earlier beaten Denmark 2-0.
Keisuke Honda's goal seven minutes before the interval helped the Japanese notch their first ever World Cup victory on foreign soil.
The Blue Samurai, struggling for goals in the run-up to the tournament, held on for the remainder of the match to the delight of their under-fire coach.
"Today our players have really done a good job," he said, but added the team needed to be more aggressive in attack.
"In the next game we will be up against Holland so we will have to go one step further and this is the first win on foreign soil in the World Cup for our team but this is not an achievement at all. What's coming next is the point," he said.
Japan face Holland in Durban on Saturday before rounding off the group with what could prove to be a pivotal encounter against Denmark in Rustenburg on Thursday 24th June.
