Aya Kyogoku was born in Japan, presumably in the 1970s, based on her career trajectory. Details about her specific birthdate and childhood remain private, but it can be inferred that her upbringing occurred during a period of significant technological and cultural change in Japan, potentially exposing her to early forms of gaming and technology.

During her formative years, Kyogoku likely received a standard Japanese education. While specific details are unknown, it's probable that she developed an interest in arts, design, technology, or storytelling. The growing popularity of video games during this period would have likely played a role in influencing her career interests.

It is assumed that Aya Kyogoku received some form of higher education, possibly related to graphic design, programming, or game development, before joining Nintendo. Given her later role, studies in fields associated with creativity and technical skills are most likely, although this is speculative.
