The Japanese government's top spokesperson says the obligations of Japan and the United States are balanced under the bilateral security treaty and the agreement is not one-sided.
Chief Cabinet Secretary Yoshihide Suga made the comment to reporters on Thursday when asked about US President Donald Trump's remarks expressing displeasure over the pact.
Trump was speaking in an interview with US media on Wednesday, before he headed for the western Japanese city of Osaka to attend the G20 summit.
He complained that the agreement was unfair, saying Japan doesn't have to help the United States at all if the US is attacked.
Suga said a Japan-US joint statement issued in February 2017 confirms that the bilateral alliance is the cornerstone of peace, prosperity and freedom in the Asia-Pacific region. Suga said the Japan-US security treaty forms the core of their alliance.
Suga said there has been no talk whatsoever about revising the treaty with the US government and he has confirmed this with the White House.
He said that article five of the treaty stipulates that Japan and the US would act to meet the common danger when either party is attacked in Japanese territory.
Suga said that under article six of the treaty, the US forces are granted use of Japan's facilities and areas for the purpose of contributing to the security of Japan.
He said that overall, the obligations of both countries are balanced and the treaty is not one-sided.
