Japan's Prince Hisahito turned 15 on Monday. He is the nephew of Emperor Naruhito and second in line to the throne after his father, Crown Prince Akishino.
Prince Hisahito became a third year student at a junior high school in Tokyo in April. The Imperial Household Agency says he has spent the last year in good health.
Agency officials say the prince and his classmates took part in a school project about people's lives during the coronavirus pandemic. They conducted interviews and surveys, and presented the results at a school festival in September last year.
Agency officials say Prince Hisahito appeared to have learned about the hardships and efforts of people in different industries and deepened his thoughts on what he and other children can do to help.
The prince's writing about a trip to the Ogasawara Islands won a literary prize for elementary and junior high school students. He attended an online ceremony to accept the award in March.
Officials say Prince Hisahito watched an online event during summer vacation to mark the anniversaries of the 2011 Great East Japan Earthquake and the 2016 Kumamoto Earthquake in southwestern Japan.
They say the prince watched the event with his family and learned about disaster preparedness, including possible roles children can play.
Prince Hisahito has been attending his second semester at school since September 1.
