Japan's lack of size and strength up front has been a traditional weakness, and that is where Miuchi comes in.
Debut: 14/7/02 v Korea
Past World Cups: N/A
Did you know? Was a surprise choice when named captain
The team's new captain is a confrontational flanker who likes to take the fight to the opposition.
He was given the responsibility of leading the team in July 2002 during their World Cup qualification.
His appointment caused a few raised eyebrows but he has since shown the doubters his ability.
Miuchi has brought the best out of his team-mates who have followed his lead, and the new skipper is noted for his formidable defence.
Strong and uncompromising in both defence and attack, he will make sure that what Japan may lack in size, they will not lack in confidence.
