110 Million Memories! (Okkusenman!) is a legendary internet anthem that originated on the Japanese video-sharing site Nico Nico Douga in the mid-2000s. The song is a lyrical arrangement of the Dr. Wily Stage 1 theme from the 1988 NES classic Mega Man 2, focusing on the bittersweet feeling of growing up and losing the innocence of childhood. The term Okkusenman, meaning one hundred and ten million, represents the countless memories of youth that fade as time passes. It became a global phenomenon, representing the peak of Niconico culture and early viral video history. Today, the meme is used to express intense nostalgia, the struggle of adulthood, or simply to celebrate the iconic 8-bit soundtrack that defined a generation of gamers.
