A senior Japanese official and Iran's foreign minister have agreed that the two countries should continue talks on ways to de-escalate tension in the Middle East.
Senior Deputy Foreign Minister Takeo Mori met Foreign Minister Mohammad Javad Zarif in Tehran on Saturday.
They confirmed that frequent visits to each other's country by their leaders have been contributing to long, friendly bilateral ties.
In June, Prime Minister Shinzo Abe visited Tehran for talks with Iran's Supreme Leader Ayatollah Ali Khamenei and President Hassan Rouhani, in an effort to ease tension between the US and Iran.
On Saturday, Mori also held talks with his Iranian counterpart, Abbas Araqchi.
Mori and the Iranian officials are believed to have discussed a US proposal to launch a maritime coalition for ensuring security in the Strait of Hormuz. It's a key route for shipping crude oil.
