- NDC Policy Brief 19-22: Towards a deeper NATO-Japan cooperation, by Marc Ozawa *
While NATO and Japan have a long history of
cooperation dating back to the 1990s, changes in their respective regional and global security environment are creating converging interests.
This, in turn, presents new areas of potential cooperation. The developments driving convergence are Russia’s war with Ukraine and possible spill over effects in
the Indo-Pacific, China’s growing global assertiveness
and military posturing in the South China Sea, and a
deepening security partnership between Russia and China. At the same time, NATO’s view is increasingly global, and Japan has signalled both a willingness and interest to deepen cooperation with NATO, exemplified
by Prime Minister Kishida’s participation in the Madrid
Summit last summer. While NATO’s short-term focus
will be deterring and defending the Eastern flank, the
current timing is right to consider deeper cooperation
in the future. This could entail expanding cooperation
beyond the ‘soft’ areas of humanitarian assistance and
non-proliferation into defence through interoperability, cyber, and intelligence. There are already lessons
from the Russia-Ukraine war that can assist in laying
the groundwork for practical steps to NATO-Japan cooperation including a focused expansion of interoperability of forces, joint exercises in the maritime domain,
political support, countering disinformation, and developing contingency plans for logistics and intelligence
cooperation in the event of military conflict.
Of all NATO’s partners in the Indo-Pacific, Japan
spends the most on defence and represents the largest
economy, about three times the size of the Republic of
Korea (ROK) or Australia. Japan is the only non-NATO member of the G7, and as the longest-standing
NATO partner beyond Europe, Secretary General Jens
Stoltenberg described Japan as a “natural partner” with shared values and challenges.1
These factors alone warrant revisiting NATO-Japan relations in light of recent
events.
