Meanings

  • 1. A specific envelope used to hold cash for gifts or payments in ceremonies and business (distinct from decorative ceremonial bags).
  • 2. A postal or administrative envelope used to submit ballots, applications, or official papers where the item must remain concealed.
  • 3. A commercial packaging form (padded or gusseted) described as an envelope for shipping small goods or documents.
  • 4. Usage in bookkeeping or payroll to refer to a packet containing pay or expense cash.
  • 5. Extended/figurative use to mean an enclosing container or cover in non-literal descriptions (e.g., a protective outer layer).

Origin

Distinct paper envelopes in Japan became common during the Meiji era (late 19th century) as Western stationery and postal systems were adopted; prior to that, written messages were typically folded and sealed without separate paper wrappers, and mass-produced envelopes gained popularity with modern postal reforms and industrial paper manufacturing.

Composition

  • 封 (fuu) – means to seal, close, or confine; conveys the idea of closure or official sealing.
  • 筒 (tou) – means tube, cylinder, or hollow container; evokes a receptacle for holding items.
  • Together the characters form the compound meaning of a sealed receptacle or container for papers—metaphorically a “sealed tube” that becomes the envelope.

Usage

Found in homes, offices, banks and post offices, envelopes are purchased at stationery shops and convenience stores and used for mailing, handing in documents, gifting cash, and filing; formality affects presentation—business correspondence often requires plain, standardized sizes and properly written addresses, while ceremonial uses employ specialized decorative covers—and postal regulations determine allowable sizes and folding methods for mailing.
💡 Tips
Visualize a small sealed tube: 封 = seal, 筒 = tube, so 封筒 (fuutou) is a sealed tube for letters—imagine sliding a letter into a short paper tube and sealing it shut.

Variations

  • 封書 (fuusho) – a sealed/formal mailed letter (emphasizes the sealed document rather than just the wrapper).

  • 窓付き封筒 (madotsuki fuutou) – window envelope used for displaying an address printed on enclosed paper.
