A remote system and a remote operation method are provided, being capable of starting promptly and completing remote operation immediately for a user. A support server 100 acquires configuration information of a user terminal 10 in response to support request from the user terminal 10, receives remote operation from a supporter, the operation corresponding to support request sent from a support terminal 150, and sends remote operation received from the supporter to the user terminal 10 as a configuration command for setting configuration corresponding to the support request from the user terminal 10. The user terminal 10 sets configuration corresponding to the support request based on sent configuration command. Where the user terminal 10 conducts configuration corresponding to the support request based on the sent configuration command, the user terminal 10 displays a user interface in a phased manner to set the configuration corresponding to remote request.
