BlackBerry's market share in Japan has shrunk to 0.3 percent from 5 percent, the daily said.
BlackBerry could not be immediately reached for comment.
The company, which changed its name from Research In Motion when it launched its new BlackBerry 10 smartphones a week ago, will continue to offer support to existing users, the Nikkei said.
