After more than two years, Japan could soon be getting a new American ambassador.

U.S. President Joe Biden on Friday formally nominated ex-Chicago Mayor Rahm Emanuel, who served as chief of staff under President Barack Obama, as the country's ambassador to Japan, the White House said.

"The alliance between the United States and Japan is the cornerstone of peace and prosperity in a free and open Indo-Pacific, and I would proudly represent our nation with one of our most critical global allies in one of the most critical geopolitical regions,” Emanuel said in a statement.
