Twenty years of Twitter!

Today, and March 21st annually, is First Tweet Day, Twitter最初のツイートの日 in Japan. It commemorates the very first tweet on this day in 2006, by co-founder Jack Dorsey. The very first post on the platform was a simple "just setting up my twttr".

But that simple line marked the beginning of a new era in online communication, where short, real‑time messages could ripple across the world in seconds. Some people use the day to look back at their own first tweets. But for all, it is a reminder how online presence has evolved and how even the smallest beginnings can spark global change.

Twitter may officially be known as "X" now, but a lot of people, myself included, continue to call it Twitter and refer to posts on the platform as "Tweets"! Twitter / X remains highly popular in Japan. In fact, it is the second most used social media platform (after LINE) in Japan.
