Abstract
"A title" is not the work itself. But the relation with the work to which it is given is very close. And it not only expresses and explains the contents, but as for it, the charm of a work influences them intuitively. In the present age, a "title" is in various fields. Furthermore, it may induce a large amount of wealth. However, the research which tackles it is rare. Though it was familiar, since the example is too much huge, researchers will not be able to hold a clue. However, the start of research is being opened by development of information machines and equipment and resources. By this report, I will try the consideration about the "title" in connection with the classic family register of Japan and China. I want to specifically try the analysis from viewpoints, such as ontology of succession nature, acceptance, and a category title.
