According to to a statement from ANA the source of the smoke is not yet known and is under investigation.
A spokesman for Osaka airport authority said the 129 passengers and eight crew were evacuated via inflatable chutes. Accordingly five people were slightly injured.
Recently, the 787 Dreamliners has suffered a number of technical problems including fuel leaks, a cracked cockpit window, brake problems and an electrical fire.
Both the U.S. Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) said they were monitoring the latest incident as part of a comprehensive review of the Dreamliner announced late last week.
