Is this the world’s oldest tweet? Viral X post in Japanese shows impossible 1992 timestamp

Published on March 27, 2026

In a curious twist of social media history, a post Eiko Kano has gone viral for allegedly showcasing the world’s oldest tweet, dated September 2, 1992. Given that Twitter, now rebranded as X, was launched in 2006, the timestamp has naturally raised eyebrows and sparked intrigue among both users and historians.

The post features content that many are interpreting as a tweet, but the timestamp appears to predate the platform’s existence by a staggering 14 years. This has led to a flurry of speculation and humor surrounding the concept of “time travel” on social media, with users jokingly suggesting that Kano may have crossed into an alternate timeline where Twitter was an active platform in the early ‘90s.

Despite the excitement, some keen-eyed users have presented alternative theories. They argue that the post may actually stem from 2011, with the unusual display of the date attributed to glitches or bugs that can occur on digital platforms. This notion has fueled further discussions about the evolving nature of social media and how it preserves or distorts the timeline of events.

As the anniversary approaches of Jack Dorsey’s first tweet, dated March 21, 2006, the viral nature of Kano’s post has rekindled interest in the history of Twitter and its cultural impact. It has also prompted users to delve deeper into the early days of social networking, examining how far the medium has come since its inception.

The humorous theories and discussions surrounding this peculiar post are a testament to the ways in which social media continues to captivate users, not just through current events, but also through its past and the lore that surrounds it. Whether or not Kano’s post holds any historical significance, it serves as a reminder of the playful engagement that defines online interactions today.
