On
January 19, 2020, the United States and Japan celebrated the 60th
anniversary of the signing of the U.S.-Japan Mutual Security Treaty. The foreign
and defense ministries of the two countries recognized this occasion by issuing
a Joint Statement on January 17, followed by celebratory messages from U.S.
President Donald Trump and Japanese Prime Minister Shinzo Abe, commemorating
the “peace, security, and prosperity” enabled by the “pillar immoveable” that
is the alliance.[i]
Through
these statements, the two governments sent two significant messages: (1) the
U.S.-Japan alliance is more critical than ever for the peace and prosperity of
the Indo-Pacific region and beyond, and (2) the two governments are committed
to continuing to strengthen the alliance. From Tokyo’s perspective, one of the
critical components of Japan’s own effort to reinforce the alliance is to
continue to modernize its defense capability to better meet the security
challenges of today and the future. In this context, Japan released two key
defense policy-planning documents in December 2018: the National Defense
Program Guidelines (NDPG), a policy document that guides Japan’s defense policy
for the next five years, and the Mid-Term Defense Program, an acquisition
planning document that supports the NDPG.
The
2018 NDPG put out “Multidomain Defense Force (tajigen tōgō bōei-ryoku)”as an organizing concept that Japan will strive towards. Explained as
deepening the concept of a “Dynamic Joint Defense Force (dōteki bōei-ryoku)”
that was laid out in the 2013 NDPG, this new concept is supposed to serve as a
vision that guides the effort to better prepare Japan to effectively meet the
security challenges that Japan will face over the next several years.[ii]
At
the time of the release, the reference made in the NDPG to the possibility of
acquiring long-range missile capability and the clear indication of Japan’s
intention to acquire an aircraft carrier attracted intense media attention.
However, the document highlighted other domains as the new priority for Japan’s
defense-planners: space, cyberspace, and the electromagnetic spectrum.
Some
of these “new” domains identified are not new to the 2018 NDPG. In fact, the
2013 NDPG already identified space and cyberspace as emerging battle domains
that can potentially affect the operation of the Japan Self-Defense Forces
(SDF) considerably. However, while these domains’ importance to the SDF’s
future operational environment was mentioned, investment in these areas was not
prioritized. What makes the 2018 NDPG’s emphasis on these areas, along with the
electromagnetic spectrum, different from previous defense policy iterations is
that they are identified as critical enablers for future SDF operations in
cross-domain environments and acknowledged as high-priority areas of
investment.
The
2018 NDPG also reiterates that the security environment in Japan’s immediate
neighborhood continues to degrade, stressing the importance of continuing to
strengthen Japan’s alliance with the United States. In addition, the NDPG
discusses the need for Japan to continue to expand its security cooperation
with other likeminded countries, particularly in the Indo-Pacific region.
Indeed, the security environment that Japan—and
the U.S.-Japan alliance broadly—faces is changing at an accelerated speed, its
unpredictability quickly growing. In addition to the threats that have
consistently been present, such as North Korea’s nuclear and missile program
and China’s growing aggressive behavior, and the impact of emerging
technologies in the battlespace, Japan finds itself in a security environment
that is becoming less and less safe, particularly given the perceived declining
commitment of the U.S. in the region. Given such circumstances, analyses that
carefully examine how Japan plans to meet these challenges are indeed
appropriate. That is why Stimson’s Japan Program decided to “go back to the
basics” and chose key challenges for Japan’s defense policy, as identified and
highlighted in the 2018 NDPG, as the theme for this year’s edition of the Views
from the Next Generation series.
