The Cipher Brief
The world's attention will be fixed on Japan as it hosts the Rugby World Cup in September and the Tokyo Olympics in 2020. Japan's cyber defenses will need to be strong enough to keep attackers out and resilient enough to restore systems should things go wrong.

Jeffrey W. Hornung
May 3, 2019
Foreign Policy
In early April, Japan deployed its Self-Defense Forces (SDF) abroad to join a multinational force not connected to the United Nations. This is the first time that SDF personnel will participate in overseas peacekeeping operations not under UN control. The difference may not seem important, but it is.

How the U.S. Is Thinking About the Quad
Derek Grossman @DerekJGrossman
Feb 7, 2019
Australian Strategic Policy Institute
The United States has been consistent in discussing the security objectives it seeks to promote through the Quadrilateral Security Dialogue. But U.S. interactions with other Quad partners have likely convinced Washington to repackage public presentation of the dialogue proceedings and manage its expectations of what the Quad can realistically achieve.

Jeffrey W. Hornung
Dec 7, 2018
Debating Japan (CSIS)
Recent meetings and otherwise relative calm between China and Japan may give the impression that their ties are improving. But because of their strategic competition and fundamental differences, it is more likely than not that their current rapprochement will fail.

Japan's Invisible Hand
Jeffrey W. Hornung
Oct 10, 2018
The Japan Times
Shinzo Abe has cemented his position as Japan's prime minister for the next three years. Now he is expected to make a concerted push for revising the Constitution, which has not been amended since 1947. But the Japanese public is not convinced of the need to revise the Constitution, making his efforts likely to fail.

Does Japan Need an Aircraft Carrier?
Jeffrey W. Hornung
Oct 5, 2018
Defense One
Japan has not possessed an aircraft carrier in more than 70 years. But that may soon change as the Japanese government is debating retrofitting a class of destroyers to turn them into aircraft carriers.

Yomiuri Shimbun
For nearly 20 years, Japan has used the North Korea threat as a legitimate rationale to build its missile defense system and cooperate closely with the U.S. in its development. This argument remains as true today as it was before the flurry of regional diplomacy began earlier this year.

Foreign Policy
India's sustained membership in the Quadrilateral Security Dialogue would fit with the goal of balancing against China to deter it from further militarizing the Indo-Pacific. But New Dehli may be getting cold feet.

Success with North Korea Still Needs Japan
Jeffrey W. Hornung
Jun 27, 2018
The Japan Times
Japan has stakes in the outcome of regional diplomacy involving North Korea. It could play a role far beyond simply writing checks for an agreement, but has not held any bilateral meetings with the other actors. Diplomats hoping to fit their approach to the realities of the geopolitical situation could benefit from Japan's active involvement.
