Japanese media said their country may deploying their Navy for the safety of shipping in the Bab el-Mandeb Strait, near the coast of Yemen.
Japan had previously said it would participate in the US Marine Alliance in the Strait of Hormuz, but would send its patrol vessels to areas beyond the Strait of Hormuz.
Japan's navy is likely to be deployed in the region for maritime security, said Yoshihide Suga, Japan's first cabinet secretary.
Such a presence, of course, will not be within the framework of the American Coalition.
Mr Suga said we would make a comprehensive decision after considering different points of view.
The main reason for Japan's presence in the region is the need to stabilize the supply of crude oil and balance Japan's relations with Iran and the United States, the secretary general of the Japanese government said.
