TOKYO — The US ambassador to Japan on Friday missed a ceremony marking the 79th anniversary of the atomic bombing of Nagasaki in protest of Israel not being invited.

Rahm Emanuel instead attended a prayer meeting at a Tokyo temple with Israeli ambassador Gilad Cohen and Britain's Julia Longbottom, who also boycotted the Nagasaki event.

Former US ambassador John Roos in 2010 became the first American representative to attend the Hiroshima commemoration and followed suit in Nagasaki two years later.

Nagasaki's mayor, Shiro Suzuki, has insisted that Cohen's exclusion from the annual event in the southern Japanese city was "not political."

Instead, it was to avoid possible protests over the Gaza conflict and ensure a "smooth ceremony in a peaceful and solemn environment."

Emanuel, former chief of staff for ex-president Barack Obama, on Friday rejected this.

"I think it was a political decision, not one based on security, given the prime minister (of Japan) is in attendance," he told reporters after the ceremony at the Buddhist temple.

The snub drew "a moral equivalence between Russia and Israel — one country that invaded versus one country that was a victim of invasion," he added.

Russia and ally Belarus have not been invited to either Nagasaki or Hiroshima since Moscow's 2022 invasion of Ukraine.

"My attendance would respect that political judgment and political act. I cannot do that in good conscience," Emanuel said.

Cohen said: "On behalf of the state and the people of Israel, we extend our sympathy and stand by the victims of the Nagasaki A-bomb, their families and the people of Japan today."

Lower level

At the Nagasaki event, Suzuki made no direct mention of Israel but expressed concerns about world peace in light of the Ukraine and Gaza conflicts.

"With no end in sight to Russia's invasion of Ukraine and fears of an escalation of armed conflict in the Middle East, important norms that have been upheld could be lost. We are facing such a critical situation," he said.

The United States and Britain sent diplomats below ambassador level to Nagasaki, as did Germany, France, Italy and the European Union. Canada and Australia reportedly followed suit.

The British and German embassies echoed Emanuel's comments about Russia and Belarus, while a spokesman for the French Embassy called Suzuki's decision "regrettable and questionable."

Cohen, who attended a similar memorial ceremony in Hiroshima on Tuesday, said last week that the Nagasaki decision "sends a wrong message to the world."

In Washington, State Department spokesman Matthew Miller on Thursday defended Emanuel's decision.

"I think our position on it and our respect for Japan when it comes to this anniversary is well-documented, and goes beyond — far beyond — the ambassador not attending one event," Miller said.

On Friday, government spokesman Yoshimasa Hayashi again declined to comment, saying it was a matter for event organizers in Nagasaki.
