In this report I restricted the discussion to the selection of the castles for this consideration and to the basic consideration. I feel disappointed that any researchers couldn't fully understand the details of the all castles on the list, generally because in their investigation they only used the reports in the present generations or used the questionnaire to the present person in charge of cultural properties.
I think that the researcher has to investigate historical documents of each castle carefully and directly, even if it is necessary to decrease the number of the castles.
