The Japanese and US governments are expected to hold a foreign ministers' meeting in Japan next month, according to sources.
The meeting would be attended by Foreign Minister Fumio Kishida and US Secretary of State John Kerry, and coincide with Kerry's tour of Asian countries. The two governments are coordinating the date.
If the meeting is held, Kishida and Kerry would discuss preparations for Prime Minister Shinzo Abe's visit to the United States, which is planned during the Golden Week holidays from late April to early May.
Kishida will explain legislative actions related to security affairs that will allow Japan to exercise the right of collective self-defence in a limited manner.
It is likely the two will also discuss a review of Japan-US defence cooperation guidelines.
They probably will confirm the need to accelerate negotiations of the Trans-Pacific Partnership free trade agreement.
Another topic that will probably come up for discussion will be what antiterrorism measures should be taken in the wake of a wave of hostage-taking by the Islamic State of Iraq and the Levant militant group.
