Olympic flag arrives in Tokyo

Tokyo governor Yuriko Koike brought the Olympic flag to Japan from Brazil on Wednesday and called for all parties to work together to host a successful Summer Games in 2020.

Koike, who was elected last month after two predecessors stepped down over scandals that clouded the city's Games preparations, was given the flag on Sunday at the Rio Games closing ceremony.

"Let's work together with everyone to hold a great Olympics and Paralympics as the Olympic flag, which just arrived, is a symbol of," she told reporters after waving the flag as she stepped off the flight at Haneda airport.

The Tokyo Games have been hit by series of issues including the scrapping of plans for the main stadium, which have led to delays in construction, and plagiarism allegations which have forced organisers to ditch the original logo for the Games.

Koike was joined on the flight by Japanese athletes who took part in the Rio Games, where Japan won 12 gold medals - their best tally since 2004 - and a record 41 overall.

Keisuke Ushiro, who took part in the decathlon in Brazil, followed Koike off the plane waving a Japanese Olympic Committee flag.
