EASTBOURNE, England (Reuters) - A wary South Africa are unsure of what lies in wait for them when they take on Japan but are conscious of the need for a bright start in their opening Rugby World Cup game in Brighton on Saturday.

It is a first meeting between the two countries and for the twice winners a trip into the unknown, leaving them without any of the expected swagger ahead of the Pool B match at the Brighton Community Stadium.
