YataLogic’s analysis

The key point of this case

Shows current progress, the next action and what counts as completion.

From official information

Officially documented uses

  • Japan Post describes its Kids’ Site as teaching materials for learning about letters and post offices through Posukuma and friends and role-playing postal delivery.
  • “How to address a letter” presents seven points in sequence: the recipient’s postal code, name and address; the sender’s address, name and postal code; and the stamp.
  • The delivery section uses character dialogue to explain how many people handle a letter, then connects to role-play.
