ランダムトレカ

• 読み: ランダムトレカ
• ローマ字: randamu toreka
• 漢字の分解: ランダム (random, from English) + トレカ (trading card, abbreviated from トレーディングカード) → randomly assigned photo card
• 発音: /ɾaɴ.da.mu.to.ɾe.ka/

意味

Random trading card; a photo card included with purchases where you don't know which member or design you'll receive.

ランダムトレカ is the engine driving the gacha-like collectibility of idol merchandise. Because you can't choose which card you get, fans buy multiple copies of the same album or product, boosting sales numbers. The randomness creates a thriving secondary market for trading and selling. While fans enjoy the excitement of 'pulling' their favorite member's card, the system is also criticized for encouraging excessive spending — essentially applying gacha mechanics to physical goods.

例文

1. ランダムトレカで推し出なくて5枚も買ったのに。
2. ランダムトレカの仕様やめてくれないかな、指名買いさせてほしい。
3. ランダムトレカだから開封する瞬間がドキドキする。
