A book does not automatically qualify for Japan Post’s international Printed Matter service. Japan Post lists books among the possible contents, but separately excludes merchandise and sale items, including books and game cards with commercial value. Decide what you are sending and why before choosing a Printed Matter rate. This is a review of published rules, not a test shipment. Japan Post: Printed Matter
“Printed on paper” is not the eligibility test
The detailed definition distinguishes different kinds of printed material. It lists photocopies and certain unfilled forms, while computer- or typewriter-produced documents have a specific exception involving two or more copies submitted together. Packaging for medicine or cosmetics does not qualify just because it carries printed text. Japan Post: qualifying and excluded contents
That means the description “paper, 300 g” is not enough to choose the service. A useful description identifies the item, whether it is merchandise, whether it has been filled in, and how it was produced. Weight becomes useful after the category is understood.
Use three hypothetical cases to find the unresolved question
The following are invented planning examples, not acceptance decisions made by a post office.
| Situation | What to check before buying postage |
|---|---|
| You sold a book online and need to mail it to the buyer | Start with the merchandise exclusion, rather than the general word “books” |
| You are sending unfilled application forms | Check that the actual forms match the listed category; do not assume completed forms have the same treatment |
| You printed one personal document from a computer | Check the detailed definition; the physical fact that a printer produced it is insufficient |
For the sold book, changing the customs description to “gift” would not resolve the service question. The shipment’s real purpose remains a sale. Choose a service that accepts the actual contents instead of changing the description to fit a preferred rate.
For a book that is not being sold, do not assume that “not a sale” settles every condition either. The official pages use both a general books category and a merchandise exclusion. If the distinction is unclear for your item, show the contents and explain the purpose at the counter before preparing a label. This guide cannot classify every personal book from its title alone.
Printed Matter does not mean customs paperwork disappears
Japan Post says material potentially subject to customs inspection can require a customs declaration and electronic customs data, using a label created with International Mail My Page. It specifically flags books and calendars as items that may be returned if required customs information is missing. Japan Post: conditions and cautions
Treat eligibility and customs preparation as two separate checks. Passing the first does not answer the second. Conversely, generating a customs label does not make otherwise excluded merchandise eligible for Printed Matter.
Before preparing the mailing, write two short statements: “This item fits the service because…” and “The customs information required for this item is…”. If either statement is based only on the word “book” or “gift,” return to the relevant conditions.
Confirm the category before closing the package
The service generally requires packaging that allows the contents to be inspected. Japan Post also specifies a “Printed Matter” or “Imprimé” marking on the address side. Japan Post: packaging and marking
There is an exception for sealed packets containing bound books or brochures, described in the English sending FAQ. This packaging exception does not override the contents rules. Keep the contents available while you resolve eligibility, then follow the instructions for the service actually selected. Do not borrow the domestic Yu-Mail inspection procedure simply because both services can involve printed material.
This guide does not quote a universal international rate or promise a delivery date. Destination-specific availability, weight and size conditions still need checking for the actual mailing. The useful first decision is narrower: whether Printed Matter is the correct category at all.
