Japanese Emperor of the Day Yuya Matsuda announces his upcoming marriage; both parties are under twenty years old. (Note: The term "日影帝" could also be translated differently depending on context, but here it seems to refer to a young, celebrated actor. "柳乐优弥" is transliterated as "Yuya Matsuda" for broader recognition in English.) A more refined translation might be: "Japanese actor Yuya Matsuda announces his marriage; both Matsuda and his partner are under twenty."
