The coat, which came in dominant blue and pink, is called a “happi,” a traditional outfit worn during festivals and special events.
The straight-sleeved clothing featured cherry blossoms, as well as other Japanese imagery.
Pope Francis immediately donned the coat, which also included words such as “gratitude,” “let’s pray together,” “may there be peace,” “what can be done to give disaster victims hope” and “we are glad that you’re the Pope.”
The moment provided some comic relief from a four-day trip that was aimed at raising awareness for the devastating effects of nuclear weapons.
The Pope arrived in Japan on Nov. 23 and left on Tuesday.
Aside from his visit to St. Mary’s Cathedral, the Pope stopped over Hiroshima and Nagasaki — the sites of the nuclear bomb droppings in World War II — and condemned the violence that affected civilians for decades.
“Convinced as I am that a world without nuclear weapons is possible and necessary, I ask political leaders not to forget that these weapons cannot protect us from current threats to national and international security,” he told followers in Nagasaki on Sunday, according to the Catholic News Service.
“In a world where millions of children and families live in inhumane conditions, the money that is squandered and the fortunes made through the manufacture, upgrading, maintenance and sale of ever more destructive weapons, are an affront crying out to heaven.”
