There has been a growing movement to reflect the voices of service users in the support service systems. Although there is some knowledge about environments that promote help-seeking behavior, no research has indicated the needs among young adults who could not seek help（poor help-seeking）despite requiring support. This study examines the environment desired by young adults with poor help-seeking toward supportive service systems.

We analyzed 206 responses from open data of a survey of young residents aged 18-39 conducted by the Komae city, Tokyo. Respondents were classified into three groups based on the presence or absence of burdens and related help-seeking behavior: the non-difficult group（50 respondents）, the help-seeking behavior group（91 respondents）, and the poor help-seeking group（64 respondents）. Sociodemographic factors and life satisfaction were compared by chi-squared tests and t-tests. Logistic regression analysis was conducted to examine the responses of human and environmental resources for facilitating help-seeking behaviors in each group.

One in two to three individuals classified into poor help-seeking group reported positive response（Yes）to some potential human and environmental resources for facilitating help-seeking behaviors such as anonymity, acceptable characteristics of service provider to consult their distress, and availability of service. However, lower rates of the positive response, lower life satisfaction, and more financial problems were found in poor help-seeking group than in other groups. It was also shown that most of reasons for the poor help-seeking were due to not knowing where to seek help.

The results suggest that young adults with poor help-seeking is unable to express their needs despite requiring support. Expanding the availability of remote service through SNS and developing the support system considering disparities related to financial problems and health literacy would be helpful for facilitating help-seeking behavior among poor help-seeking group.
