The 'Reiwa' meme originates from the official announcement of Japan’s new imperial era on April 1, 2019. Chief Cabinet Secretary Yoshihide Suga presented the name 'Reiwa' to the public by holding up a traditional calligraphy placard. The stoic delivery and the blank-canvas nature of the sign immediately turned it into a global sensation. It is primarily used as a 'sign-holding' template where users replace the kanji with their own jokes, political statements, or fandom references. The meme symbolizes the dawning of a new age, making it perfect for dramatic announcements or ironic declarations of personal milestones.
