Emperor Naruhito ascended the throne on May 1, a day after his 85-year-old father, now referred to as Emperor Emeritus Akihito, became the first living Japanese monarch to abdicate in over 200 years.
In accordance with his ascension, the new imperial era of Reiwa (meaning "beautiful harmony") began, bringing the 30-year Heisei (meaning "achieving peace") Era to a close.
The 59-year-old earlier signaled his intent to adapt to "the changing times," while also saying his years with his parents would serve as "major guideposts" for him as he performs his nonpolitical duties as the symbol of the state in the years ahead.
