The government said Tuesday it will send invitations to 195 nations for events in the fall to mark Crown Prince Naruhito's enthronement, following Emperor Akihito's abdication next month.

The abdication ceremony, set to begin at 5 p.m. on April 30, is expected to be attended by about 300 guests, including Prime Minister Shinzo Abe and his Cabinet members. Abe will offer words of gratitude before the 85-year-old Emperor speaks to the representatives of the people, the government said.

All 195 nations are recognized by Japan as states.
