We Welcome Entry into Force of the Treaty on the Prohibition of
Nuclear Weapons and Urge the Japanese Government to Immediately
Consider Joining the Treaty
Today, on January 22, the Treaty on the Prohibition of Nuclear Weapons (TPNW) enters into
force, rendering nuclear weapons illegal for the first time in history. From today, this
international law prohibits all activities involving nuclear weapons, including their use,
possession, threat to use, development and testing.
The entry into force of the TPNW is an historic accomplishment, to which joint efforts of the
Hibakusha of Hiroshima and Nagasaki and civil society in and out of Japan, with an
overwhelming majority of governments of the world, made great contribution, tirelessly
appealing, “No more Hiroshimas, No more Nagasakis” and “Abolish nuclear weapons”. We
wholeheartedly welcome the entry into force of the treaty.
With the coming into force of the TPNW, our struggle for the abolition of nuclear weapons is
entering a new stage. We must make 2021 a year of great advance to realize a world without
nuclear weapons, building on the TPNW as leverage.
Under the COVID-19 pandemic, clinging onto nuclear weapons by major nuclear weapon
states, including the U.S. and Russia, is placing human community in greater crisis. A
nuclear weapon-free world is a common goal of the international community. These nuclear-
armed states must take the lead in achieving it. Especially, they should make sincere effort to
make progress in nuclear disarmament towards the 10th NPT Review Conference in August,
and the First Conference of States Parties to the TPNW to be held later this year.
We call on all anti-nuclear peace movements and civil society organizations in the nuclear-
armed states as well as “nuclear umbrella” states to launch actions in solidarity to urge their
own governments to join the TPNW.
In achieving a nuclear weapon-free world with the TPNW as leverage, the role of Japan, the
only country to have suffered the atomic bombing, will be critically important. However, the
Japanese government has refused the TPNW. In his administrative policy speech delivered to
the January Ordinary Diet Session, Prime Minister Suga did not utter a word about the
TPNW in spite of the treaty going into force, and even stated in the press conference that he
had no intension to sign it.
Changing Japan into a country to play a role befitting the A-bombed country is an
international mission the Japanese peace movement should fulfill. Japan’s accession to the
TPNW commands a majority support from the Japanese people. In order to achieve this task,
we call on all the people of Japan to join and develop the “Signature Campaign to Urge the
Japanese Government to Sign and Ratify the TPNW” into a broad-based national movement.
