TOKYO (AFP) - A Boeing Dreamliner operated by All Nippon Airways made an emergency landing in the west of Japan on Wednesday, the airline said, with media reports saying smoke had been seen inside the aircraft.

"It made an emergency landing at Takamatsu because there was an error message during the flight," from Ube in the far west, bound for Tokyo, ANA spokesman Naoko Yamamoto said.

Television pictures showed emergency chutes deployed from the plane at the airport in Takamatsu, on Japan's fourth largest island of Shikoku.

Jiji Press reported smoke had been seen inside the cockpit. If confirmed, it would constitute yet another blow to the Dreamliner's reputation after more than a week of bad news.

ANA said 129 passengers and eight crew on board, with Jiji and broadcast NHK saying none was injured.

"It is true that the aircraft has recently seen a series of troubles," said the ANA spokesman. "But we cannot say if this has something in common with previous problems".
