Submission Request to W3C from Vivliostyle

Submitted Materials

We, W3C Member Vivliostyle, hereby submit to the Consortium the following report, comprising the following document attached hereto:

  1. Current Status of Japanese Typography Using Web Technologies
  2. Analysis of requirements in JLREQ
  3. Analysis of requirements in EPUB3 Petition of Japanese Typesetting

We request the Submission be known as the Current Status of Japanese Web Typography Submission.


In this document, we study whether or not CSS and HTML are sufficient for the layout of paginated documents in Japan. Specifically, we study requirements in two documents: W3C JLREQ and EPUB3 Petition of Japanese typesetting from EBPAJ. We show which requirement is covered by which CSS specification and supported by major browsers. We conclude that CSS as of now is quite good for Japanese paginated documents and that it will become even better if a few more modules (most notably Paged Media) are fully developed and implemented.
