In Japan and China, the rule is the surname (family name) comes first, followed by the individual's first name.

Example: Kurosawa Akira

Only a close circle of friends or family would ever use the individual's first name in either of these countries. This highlights the importance of family in China/Japan.

When the film's credits are translated into English, some translators leave the last name first, others put the first name first. This probably leads to a lot of the errors you see on Web sites, etc...
