[SUMMARY] In this study, we investigated how people with chronic obstructive pulmonary disease（COPD） manage their daily life, particularly the physical and social aspects. The 6 subjects included people with moderate （stage II） COPD, all were men ＞ 65 years old. We collected data using semi-structured interviews, and analyzed the data using a qualitative method. The results identified the following 7 characteristics ; “paying more attention to the body regions unrelated to COPD than those related to COPD.” , “getting along with family or acquaintances without simultaneously considering COPD.”, “ not considering COPD, and neither emphasizing nor hiding that they have COPD.”, “ leading an easy daily life, not thinking of serious things”, “ choosing daily activities based on the awareness that they are aging.” , “devising plans to ease symptoms or maintain health.” , and “becoming strongly aware of the harmfulness of tobacco strongly, and deciding to quit smoking.” . We found that the subjects manage their daily life in conscious and unconscious ways. Simultaneously, we revealed that the subjects manage their daily life without considering the fact that they have COPD. Based on the results of this study, the following recommendations are made to improve nursing care support : １） advise people with moderate COPD to become more conscious of COPD, to the extent not experiencing negative effects on their mental and social aspects, to prevent it from becoming more severe, : and 2） urge people with moderate COPD to have a negative view of tobacco, to successfully quit smoking.
