Trump discussed the Syria situation with his national security team at the White House on Thursday.
According to the sources, the specific response being considered in the event of US military action against Syria is Japan's "support for the USA resolve to fulfill its responsibility to prevent the use of chemical weapons".
At stake in Syria is the potential for confrontation, if not outright conflict, between the US and Russian Federation, former Cold War foes whose relations have deteriorated in recent years over Moscow's intervention in Ukraine, its interference in the 2016 USA presidential election and its support for Syrian President Bashar Assad.
That prompted Mr Trump to tweet: "Russia vows to shoot down any and all missiles fired at Syria".
US President Donald Trump had earlier warned regime-backer Russian Federation that "missiles will be coming" to Syria over the alleged attack in Douma that rescuers said killed 40 people.

Japan will only support U.S. President Donald Trump's "resolve" to prevent any further use of chemical weapons in Syria, the sources said.
Post-World War II Germany typically has been reluctant to engage in military action, and parliamentary approval is required for any military missions overseas.
Chancellor Angela Merkel said after speaking with Macron on Thursday that Germany won't participate in possible military action in Syria, but supports sending a message that the use of chemical weapons is unacceptable.
But British involvement in further military intervention is controversial at home, in a country still haunted by its role in the US-led invasion of Iraq.
Syria and Russia have denied using poisonous gas in Douma on April 7, with Russian Foreign Minister Sergei Lavrov saying that Moscow had "irrefutable" evidence that the attack in Douma was a "staged event".
