A post-concert survey handed out at a show by singer and actor Mitsuhiro Oikawa (及川光博), widely known by his nickname “Mitchy,” has gone viral on X after a fan pointed out an unusual detail: the age field is explicitly labeled as “self-declared,” letting attendees write down whatever age they like.
The post, shared by X user @mcr_con, showed a photo of the survey with the age question marked “age (self-declared)” rather than simply “age.” The post quickly racked up thousands of likes and reposts, with commenters calling it a “godly design” and praising what they described as the “prince’s consideration” for fans who may not want to reveal their real age.
Replies to the post were largely playful and appreciative. One user joked, “So it’s okay to just write a self-declared age!?” while another wrote, “I’m torn over what age to put down.” Others guessed at what age they personally would list, with one commenter joking they would go with “about 23.” Several fans framed the gesture as typical of Oikawa, with comments such as “Mitchy is so kind” and “Mitchy really thinks of everything, no matter where you look.”
As of this report, neither Oikawa nor his official concert staff have issued a public comment explaining the reasoning behind the survey’s wording.
