Akihiko Kondo

is a Japanese man known for symbolically marrying the fictional Vocaloid character Hatsune Miku in 2018 during a formal wedding ceremony. In high school, Kondo had an interest in real women, but he was rejected by them. Soon after, he decided he would not marry one. Later, Kondo was bullied at work and took sick leave due to depression. During his leave, in 2007, Kondo discovered Hatsune Miku; this helped Kondo return to the workplace. In 2017, he purchased a Gatebox device that allowed people to interact with holograms, including Hatsune Miku. Kondo's interaction with the hologram made him sure of marrying the character. He arranged a formal wedding which cost 2 million yen and was attended by 39 people; it received mixed reactions.

Since then, Kondo has given lectures about his relationship, including at Kyoto University. He has since identified as fictosexual—people who have romantic attraction to fictional characters. In 2023, Kondo founded the General Incorporated Association of Fictosexuality to help the public's understanding of the subject. Sources have identified Kondo as a fighter for the rights and acceptance of fictosexuals; a professor described him as "a pioneer for the fictosexual movement." Kondo was first romantically interested in a fictional character when he was in fifth grade. Kondo and Hatsune Miku's honeymoon was in Sapporo, the headquarters of Crypton Future Media. Kondo booked flights and a hotel room for two. to provide comfort to fictosexuals, hold meetings with people that have similar views, and improve the understanding of the subject by the public.
