North Korean athletes took part in the 2018 Pyeongchang Winter Olympics held in neighboring South Korea, with the two nations fielding a unified team in women's ice hockey and one pair of North Korean figure skaters qualifying. International Olympic Committee (IOC) head Thomas Bach has said the IOC is committed to promoting Korean peace efforts.

North and South Korea have told the IOC they would like to march together in Tokyo, and have also officially requested to enter joint teams in the qualifying process for four sports - women's basketball, women's hockey, the judo mixed team event and some men's and women's rowing teams.

Japanese Olympics minister Yoshitaka Sakurada told parliament on Wednesday that the government will review allowing athletes from the North to take part, Kyodo news agency said.

"The Olympics and Paralympics is the world's largest peace event, and it is desirable to have as many participants as possible," Sakurada was quoted as saying.

He added that the move will require understanding "in a number of areas" and that he will work with other officials to deal with it.

Japan instituted a number of sanctions against North Korea following a series of nuclear and missile tests that include not allowing its citizens to enter. Ties are also strained as the result of Pyongyang's abductions of Japanese citizens to train them as spies decades ago.

Sakurada's comments on Wednesday mark a change from last year, when he was quoted by Japan's Sankei Shimbun daily shortly after taking office as saying that solving the abduction issue, which Prime Minister Shinzo Abe has emphasized during his years in office, was a pre-requisite for the North Korea's athletes to take part.
