The ongoing United Nations General Assembly in New York has seen a new phase emerge in Japan's diplomacy, with Fumio Kishida likely taking on a larger role in representing the country on the world stage as he struggles to build a political legacy domestically.

Kishida’s packed agenda for his three-day stay in the United States reflected how his foreign policy priorities have largely remained unchanged since he assumed the premiership.

Hours after he landed in the United States on Tuesday, he took part in a multilateral meeting, co-chaired by Japan, with the aim of reviving negotiations on a treaty to ban the production of fissile material for use in nuclear weapons — known as the Fissile Material Cut-off Treaty.
