The Japanese and U.S. governments are set to arrange an official trip by U.S. President Barack Obama to Japan in April, people familiar with bilateral relations said Wednesday.

During the trip, Obama and Prime Minister Shinzo Abe will reaffirm their commitment to strengthening the bilateral alliance in light of the growing regional presence of China and North Korea's nuclear development programs, they said.

It would be Obama's first official visit to Japan since November 2010, when he attended a summit of the Asia-Pacific Economic Cooperation forum in Yokohama.
