Oshikatsu (推し活), a term combining “oshi” (推し, favorite) and “katsu” (活, activity), represents the devoted practices of fans who actively support their favorite idols, anime characters, and public figures. From attending concerts and collecting merchandise to engaging in online fan communities, oshikatsu has become a major force in Japan’s entertainment industry, influencing everything from consumer spending to brand marketing strategies.
The Evolution of Oshikatsu: From Idols to Anime and Beyond
The roots of term can be traced back to Japan’s idol boom in the 1970s and 1980s, when stars like Seiko Matsuda, Hikaru Genji, and SMAP gained massive followings. Fans would attend concerts, buy records, and join official fan clubs. The trend intensified in the 2000s with the rise of AKB48, whose “election system” encouraged fans to purchase multiple CDs to vote for their favorite members.
Today, oshikatsu extends beyond traditional idols to anime, video games, VTubers, and even corporate mascots. Brands have capitalized on this cultural movement, creating exclusive merchandise and events tailored to dedicated fans.
