Introduction: Loneliness in Japan, accentuated by demographic challenges and the hikikomori phenomenon (extreme social withdrawal), has raised concerns. This study critically examines loneliness dynamics, questioning assumptions embedded in hikikomori classifications. The term “hikikomori,” originally signifying prolonged home stay, requires nuanced exploration, especially regarding outgoing behaviors’ relationship with loneliness.
Objectives: Investigating the intricate connection between outgoing behaviors and loneliness, this study questions the effectiveness of existing hikikomori classifications. Aiming to understand if these classifications accurately represent the loneliness spectrum across age groups, the research emphasizes the significance of comprehending loneliness dynamics amid societal challenges. The study explores an array of factors influencing loneliness, including demographics, mental health, and outgoing behaviors, advocating for a reassessment of assumptions linked to hikikomori classifications.
Methods: This secondary analysis employed data from a nationwide Internet addiction survey conducted in July 2012. A sample of 623 participants, representative of Japanese internet users aged 16 and above, was included for analysis. Loneliness was assessed using the UCLA Loneliness Scale, and exposure variables included demographic, mental health, outgoing behaviors, and lifestyle factors. Statistical analyses encompassed descriptive statistics, one-way ANOVA, chi-square tests, and logistic regression.
Results: Significant differences were observed in loneliness scores based on sex, age, marital status, employment, and outgoing behaviors. Mental health factors, including dissatisfaction with life and romance, life stress, and psychological distress, emerged as strong contributors to loneliness. The study challenges existing hikikomori classifications, suggesting they may not fully encapsulate the loneliness experiences of individuals engaged in routine school or work activities.
Conclusion: Findings underscore the need for a reevaluation of hikikomori, emphasizing loneliness as a complex and multifaceted issue in Japan. The study advocates for nuanced strategies to address loneliness, considering diverse demographic vulnerabilities. Limitations include the pre-pandemic sample and potential unmeasured confounding factors. -

ひきこもり支援センターや総合相談窓口のほか、ひきこもりを対象とした「居場所づくり」の実践も広がりを見せており、ひきこもりの経験者をピアサポーターとして養成するプログラムもひきこもり支援対策の一つである。大仙市におけるひきこもりの経験者自体が維持してきた居場所「ふらっと」に有償ピアスタッフシステムを導入してみた。本研究はピアスタッフシステムの効果について検討した。ピアスタッフシステムは利用者の居場所に対する安心感や楽しさを促進する効果があることがわかった。一方、ピアスタッフに挑戦する側にはポジティブ、ネガティブ両面の影響があることに注意する必要がある。報酬と役割を発生させることで、ポジティブな責任感と自信や趣味を通じた楽しさにつながる一方で、ピアスタッフは無理に自分を良く見せようとする場合もある。ピアスタッフの意義およびピアスタッフシステムの有効性を、ピアスタッフ自身も実感できるようになる工夫がさらに必要であると思われた。

There have been few population studies of hikikomori (that is, prolonged social withdrawal and isolation), and the basic correlating factors of hikikomori are yet to be identified. Therefore, this study aimed to identify the associated basic characteristics and psychiatric factors of hikikomori. Data were obtained from the Survey of Young People’s Attitudes of 5,000 residents (aged 15–39 years) who were randomly selected from 200 urban and suburban municipalities in Japan in February 2010. The chi-square test and multiple logistic regression were used in the analysis. The data contained 3,262 participants (response rate: 65.4%); 47.7% were men (n = 1,555) and 52.3% were women (n = 1,707). Its prevalence was 1.8% (n = 58), and 41% had been in the hikikomori state for more than 3 years. There were fewer hikikomori people in neighborhoods filled with business and service industries. Significantly more men were in the hikikomori group (65.5%) than in the non-hikikomori group (47.3%). The hikikomori group was more likely to drop out of education (p < .001) and to have a psychiatric treatment history compared with non-hikikomori (37.9% vs 5%, p < .001). The multiple logistic regression analyses revealed that interpersonal relationships were significantly associated with hikikomori across three models (Model 1 adjusting for all basic characteristics, OR = 2.30, 95% CI = 1.92–2.76; Model 2 further adjusting for mental health-related factors, OR = 2.1, 95% CI = 1.64–2.68; Model 3 further adjusting for a previous psychiatric treatment history, OR = 1.95, 95% CI = 1.52–2.51). Additionally, the hikikomori group was more likely to have suicide risk factors (Model 1: OR = 1.85, 95% CI = 1.56–2.20; Model 2: OR = 1.33, 95% CI = 1.05–1.67), obsessive–compulsive behaviors (Model 1: OR = 1.57, 95% CI = 1.20–2.05), and addictive behaviors (Model 1: OR = 1.93, 95% CI = 1.37–2.70). This is the first study to show that hikikomori is associated with interpersonal relationships, followed by suicide risks. Hikikomori people are more likely to be male, have a history of dropping out from education, and have a previous psychiatric treatment history.

Abstract
Background
We examined the association between caregiver burden and work productivity (i.e., absenteeism, presenteeism, and overall work impairment) among working family caregivers of people with dementia and whether job characteristics (i.e., job demands, job control, supervisor and coworker support) moderate this association.
Methods
A cross-sectional correlational study design using a web-based questionnaire survey was conducted among 379 Japanese working family caregivers of people with dementia (105 female, age range 20–77) in May 2016, which measured caregiver burden, work productivity, care situation, job characteristics, and demographics. Caregiver burden was designated as an independent variable and each aspect of work productivity as a dependent variable in a hierarchical multiple regression analysis, adjusting for demographics. Interaction terms between caregiver burden and each job characteristic were also included in the model.
Results
Caregiver burden was significantly and positively associated with presenteeism (β = 0.219, p < 0.001) and overall work impairment (β = 0.181, p < 0.001), while the association of caregiver burden with absenteeism was not significant (β = − 0.003, p = 0.953). Interaction effects of caregiver burden × coworker support on presenteeism (β = − 0.189, p = 0.023) and overall work impairment (β = − 0.172, p = 0.034) were significant. According to simple slope analyses, caregiver burden was greater at lower levels of coworker support compared to higher levels of coworker support for both presenteeism and overall work impairment.
Conclusions
Our study suggests that higher caregiver burden is associated with a decrease in work productivity. Additionally, coworker support appears to buffer the association of caregiver burden with presenteeism and overall work impairment among working family caregivers of people with dementia. -

Hikikomori is a recent phenomenon among young adults in which they isolate themselves from social contacts and responsibility for more than 6 months. This problem has assumed epidemic proportions in Japan and has been widely discussed across disciplines. Previous studies have associated hikikomori with a maladaptation to structural change, an emergent mental problem that needs new diagnosis, or an under-diagnosed schizophrenic disorder. Most previous work has adopted a clinical perspective, and there have been no qualitative studies exploring the individual feelings of people suffering from the syndrome. We adopted a qualitative method using a grounded theory approach. Data collection and analysis took place between September 2006 and August 2008. Theoretical sampling included eight informants from snowball sampling and an online observation consisting of 160 online participants. Analysis focused on informants’ first- and second-person experiences of hikikomori. Data analysis revealed one overriding theme: coping difficulties consisting of the two categories stasis and expression. As a result of conflicting demands and reduced autonomy, respondents experienced stasis, which prevented them from moving forward; “hiding” or “avoiding” heightened the expression of their behaviors. This is the first study to explore the in-depth experience of individuals suffering from hikikomori syndrome in a non-clinical setting. We argue that hikikomoriis not a result of asocial behavior, but rather an anomic response to a situation that informants felt powerless to change and from which they could see no way out. We also observed that feelings of hopelessness and relationship fatigue might be overcome by introducing a relaxed social environment that people can control during rehabilitation.

Background: Study on the medium- to long-term effect of a great earthquake on health among the victims is limited. The purpose of the present study was to investigate the medium-term (i.e., three months) effect of the Great East Japan Earthquake (occurred on March 11, 2011) on health conditions (i.e., blood pressure, hemoglobin A1c [HbA1c], blood sugar, triglyceride, and total cholesterol) among the victims, by comparing with the control population.
Methods: In June 2011, taking blood pressure and blood tests were conducted for a total of 159 victims who had stayed in the shelter located in the Tohoku region since the Great East Japan Earthquake. The same tests were conducted for a total of 1,048 control participants in Tokyo from October 2010 to December 2011. Analyses of covariance and multiple logistic regression analyses were conducted.
Results: Compared with the control group, the victim group had significantly higher systolic and diastolic blood pressure; lower HbA1c, blood sugar, triglyceride, and total cholesterol, after adjusting for age and sex. In a similar way, the victim group had a significantly higher prevalence odds ratio of hypertension; lower prevalence odds ratios of diabetes mellitus, high blood sugar, high triglyceride, and high total cholesterol than control group.
Conclusions: The present study revealed that the prevalence of hypertension is higher among the victims of the Great East Japan Earthquake. Lower prevalence of diabetes mellitus, high blood sugar, high triglyceride, and high total cholesterol among the victims may be explained by the continued inadequate diet issues after the earthquake.
