We are examining the situation in the region, and the consequences of the attack,' said Itsunori Onodera.
He told reporters at the Defense Ministry in Tokyo that Japan will analyze what kind of impact the worsening of relations between the United States and Russia could have on the situation in North Korea, according to Kyodo News.
The US, the UK and France attacked Syria based on an unproven claim that the Syrian Army has used made a chemical attack on April 7 on a rebel-held town near Damascus.
It is noteworthy that the US vetoed the Russian-drafted resolution at the UNSC. The resolution entailed an impartial scrutiny of the incident be done.
Some media wrote that 'Japan's support for the resolve behind the reasoning for the strikes echoes its response to a US air strike on a Syrian airbase in April last year in retaliation to another alleged chemical attack,' wrote Kyodo News.
'Speaking to reporters after the meeting of the National Security Council of Japan, Foreign Minister Taro Kono denied that the wording of Japan's message of support means it holds a different attitude from the United States and other allies.'
When asked if the strikes were legitimate, Kono said because Japan is not one of the parties, it is 'not in a position to make a legal evaluation of an action'.
'If we can't determine who used (the chemical weapons), it's difficult to support the strikes themselves,' a government source said.
This is while Japan's Prime Minister Shinzo Abe had said on Saturday that Japan supports the decision by the United States, Britain and France to launch strikes on Syria targeting sites associated with the country's chemical weapons capabilities.
'The Japanese government supports the resolve of the United States, Britain and France not to allow the proliferation or use of chemical weapons,' Abe told reporters in Tokyo after a meeting of the National Security Council.
