Button is big in Japan

2009 world champion Jenson Button talks to Jake Humphrey about his special relationship with Japan.

The 2009 world champion has a Japanese girlfriend and is wearing a special helmet for Sunday's race at Suzuka, which he plans to auction in aid of the victims of the devastating earthquake and tsunami that hit the North-East of the country in March.

He also discusses his new contract with McLaren, and admits Sebastian Vettel deserves to become world champion for a second time in 2011.
