TOKYO - World champions Germany secured the final spot in this year's Beijing Olympics men's hockey tournament after overpowering hosts Japan 4-0 on Sunday.

The world's top-ranked side won all six of their matches in the final Olympic qualifying tournament in Gifu, scoring 34 goals without conceding one.

Christopher Zeller scored twice for the Germans, who had defeated Japan by the same scoreline in midweek. They also racked up an 8-0 win over Italy and pummelled Switzerland 10-0.

Japan, bidding to reach their first Olympic tournament since the 1968 Mexico Games, had their chances but were guilty of poor finishing, in contrast to the clinical Germans.

Florian Keller smashed in Germany's opening goal after 15 minutes before Zeller doubled their lead moments into the second half.

Zeller added another goal in the 47th minute and Sebastian Draguhn completed a comfortable victory for Germany with a smart finish two minutes from time.
