推し活
おしかつ
oshikatsu
= “oshi activities” — actively supporting your favorite idol, character, or artist
Oshikatsu fuses oshi (your favorite) with katsu (activity), turning fandom from a passive hobby into a full lifestyle. It is not just liking someone from a distance — it is the buying, traveling, decorating, and cheering you actively do for them.
Oshikatsu literally combines 推し (oshi) and 活動 (katsudou, activity) into the shortened compound 推し活. Oshi itself comes from the verb 推す (osu, “to push” or “to recommend”) — the person you push forward and champion above all others. Oshikatsu is everything you do to support that oshi: collecting guzzu (goods like photocards, acrylic stands, and keychains), attending raibu (live concerts) and events, making ensei (遠征) trips (traveling specifically to see your oshi), decorating a itabaggu (a bag covered in pins and badges of your oshi), organized cheering (ouen) at shows, and budgeting money specifically for these pursuits, often called kakin (spending/investing). What started as niche idol-fan behavior in the 2000s and 2010s has become a mainstream, media-covered phenomenon in Japan, with entire product lines, cafes, and merchandising built around supporting an oshi of any kind — idols, anime characters, VTubers, athletes, or actors.
Keep the roles straight: oshi (推し) is the person or character you support, while oshikatsu (推し活) is the activity of supporting them. You can turn it into a verb with suru: oshikatsu suru means “to do oshi activities.” The word carries a warm, wholesome connotation in Japanese — it is framed as a positive, identity-affirming hobby rather than an obsessive one, which is different from more negative fan stereotypes. It also implies active participation: someone who only watches from afar without buying goods, attending events, or actively cheering is usually just called a fan, not someone doing oshikatsu.

Formal / Cultural context
推し活市場は近年急速に拡大し、企業も専用商品を展開している。
Oshikatsu shijou wa kinnen kyuusoku ni kakudai shi, kigyou mo senyou shouhin wo tenkai shite iru.
The oshikatsu market has expanded rapidly in recent years, with companies now developing dedicated product lines for it.
The roots of oshikatsu trace back to the AKB48 era of the late 2000s, when fans were encouraged to pick a specific member to support through handshake events and elections, cementing the idea of a personal oshi rather than just liking a group as a whole. That single-target devotion — one member, one character, one performer you champion above the rest — became the emotional core of the practice and later spread far beyond idol groups into anime, gaming, and eventually VTubers, whose fans built some of the most elaborate oshikatsu rituals around live streams and digital merchandise.
In the 2020s, oshikatsu crossed over from subculture into mainstream Japanese life. It won a spot on the annual list of buzzwords, and businesses outside the entertainment industry — stationery brands, transparent bag makers, even banks offering “oshikatsu savings accounts” — began designing products around it. This commercialization turned what used to be a private, sometimes stigmatized hobby into something openly celebrated and economically significant, discussed on morning talk shows and covered in marketing reports about Japan’s fan economy.
Beyond the spending and collecting, oshikatsu is often described by fans in emotional terms — having an oshi to support gives structure and motivation to daily life, a sentiment summed up in the popular phrase that your oshi is your reason to keep going (oshi ga ikiru gendouryoku, 原動力 meaning “driving force”). This framing has made oshikatsu resonate as more than consumerism: for many, it is a self-care practice, a source of community with fellow fans, and a meaningful outlet during stressful periods of work or study.
