The sun streamed in through the windows of Peter's 11th birthday party in February 2009 creating a magical atmosphere.

Everyone listens intently to the Gyoji's instructions - well, nearly everyone.

The early evening mist starts to roll down from Mount Fuji.

Not even in Japan do they get to fight on the national flag.

The boys eagerly help get the previous combatant out of his blubbery body armour.

These young sumo wrestler are totally on fire.

It can be difficult to see across the battlefield but there is no doubt about who has gone down.

Opponents stand large and threatening, staring each other down.

The ultimate in sibling rivalry. In this case the looser got to load the dishwasher that evening.

Launching through the mist and the unmistakable sound of cellulite against cellulite can be heard.

Everyone studies the scoreboard to see which team has won.
