Tatan (Fans of Other Members)

Tatan (Fans of Other Members)

"Tatan" (他担 - literally "other-in-charge") is a Japanese subculture slang term referring to fans who support members of a group other than one's own favorite (Oshi).

In multi-member J-pop groups, theater ensembles, or mobile games with large rosters, "Tatan" is a foundational term used to coordinate merchandise trades, discuss group dynamics, and set boundaries within the community.

Key Takeaways (30-Second Summary)
  • Fandom Coordinates: A label that helps fans define their social circles and align trading agreements based on whom they support.
  • Merchandise Trading Partners: Ideal allies for blind-bag trades, as they want the characters you didn't pull and vice versa.
  • Low-Drama Relationships: Since they support different members, there is minimal romantic jealousy or status competition compared to "Dotan" (same favorite) connections.

Origins in Johnny's Fandoms

The word "Tatan" evolved from Johnny & Associates idol groups, where fans declared their loyalty by saying they were "in charge of" (Tantou) a specific member. Under this taxonomy, if you are a fan of Member A, fans of Member B are "Tatan." This nomenclature has since spread into anime fandoms, voice actor projects, and global K-pop circles, acting as the standard term for fans of alternative bias members.

Fandom friends trading trading cards

Fan A: "I bought five blind packs and ended up with three of Ken's cards, but my oshi is Rin."

Fan B: "Don't worry. I have a Tatan friend who supports Ken. I'll ask her if she has Rin's card to trade with you."

Terminology Matrix: Jitan, Dotan, and Tatan

Term Definition
Jitan (自担) Your primary favorite ("my bias").
Dotan (同担) Fans who share the exact same favorite as you.
Tatan (他担) Fans of other members in the same group.

Inter-Fan Etiquette Rules

Even though you do not share the same favorite, never make denigrating remarks about other members—such as calling them "unpopular" or "weak performers." Every member is precious to their respective fans. Celebrate the group as a whole, support each other during ticket draws, and maintain respectful boundaries to ensure a healthy community space.
