However, the country said it will send officials with direct ties to the competition, including politician Seiko Hashimoto, head of the Tokyo 2020 organising committee, as well as the heads of the domestic Olympic and Paralympic committees.

Chief cabinet secretary Hirokazu Matsuno told a regular news conference: "We have no plans to send a government delegation."

Asked if the decision was a diplomatic boycott, he replied: "We don't use a particular term to describe how we attend."

"Japan believes that it is important for China to guarantee the universal values ​​of freedom, respect for basic human rights, and the rule of law, which are universal values ​​in the international community," he added.

Japan considered these points in making its decision, he said.

Earlier this month Prime Minister Boris Johnson said no UK government minister or official was expected to attend the Games in what he described as "effectively" a diplomatic boycott.

The US, Australia and Canada have made similar decisions.

Japan, whose largest trading partner is China, has taken a softer stance than its western allies on human rights concerns in Hong Kong and Xinjiang.

China has repeatedly denied human rights abuses against the Uyghur population but there have been claims of torture and deaths inside the notorious re-education centres.

Fumio Kishida, Japan's prime minister, created a special advisory position to tackle the issue after making human rights a key part of his diplomacy.

In recent weeks he has been asked repeatedly what he would do about the Beijing Olympics but only said he would make a decision in Japan's national interest.

Public broadcaster NHK said he has faced rising pressure within his ruling Liberal Democratic Party to take a tougher position on China.

China has criticised the US and other countries for going against the spirit of the Olympic Charter, which requires political neutrality.

The Games will begin on 4 February, with Japanese athletes taking part as scheduled.
