Editor's Take:
Prince Hisahito is expected to become Emperor of Japan one day. His birth ended a long wait for a male heir. That eased pressure for changes to the succession law. He has a keen interest in insects and nature. He has co-written a scientific paper on dragonflies. His coming-of-age ceremony was a major national event. He is studying life sciences at university. He keeps a fairly private student life.
