On the Publication of Defense of Japan 2020
Minister of Defense
KONO Taro
Thank you very much for taking a look at the 2020 version of the Defense White Paper.
The Defense White Paper was first published exactly 50 years ago, in 1970, based on
then Defense Agency Director-General NAKASONE Yasuhiro’s strong conviction that
“more than anything else, it is the understanding, active support, and cooperation of the
people that is essential to the defense of the nation,” at a time when the general public
still had a strong negative perception of the Self-Defense Forces (SDF).
Since then, as the international situation has changed dramatically and the
uncertainty over the security environment surrounding Japan has grown rapidly, the
role and the field of activities of the Ministry of Defense (MOD)/SDF have broadened
to cover the space, cyberspace and electromagnetic domains.
Although dramatic changes unimaginable half a century ago have occurred,
widespread understanding and support from the Japanese people continue to be
essential in any era in order to defend their peaceful lives and Japan’s territorial land,
seas and airspace.
We believe that Mr. Nakasone’s conviction lives on in the current Defense White
Paper, which marks the 50th anniversary of publication. We are looking forward to
your reading it.
In compiling the 2020 version of the Defense White Paper, we pursued ease of
understanding and user-friendliness. Below, let me explain the notable features of the
white paper.
