The Creative Commons Weblog mentions Japanese work on a "free use mark".
I found some more pages on details. They are in Japanese however.
One is a working document of Monkasho (the Ministery of Education, Culture, Sports, Science and Technology) of December 24, 2002.
It lists four "free use marks" and gives some explanation about each.
Free for non-commercial use.
Free for use for handicapped people.
Free for educational use.
This document is accompanied by a paper on the contract law questions concerning use of the mark (for example: what happens if someone used one of the marks in error).
An earlier paper of September 2002 discusses all of the above plus
- restrictions on the number of people for which a copy may be provided legally
- a restriction not to publish on the Internet
- a restriction against derivative works.
