Professor Yasuhiro Kotera's research lab focuses on the psychological and mental health impacts of environmental and workplace interventions, particularly nature-based therapies such as shinrin-yoku and nature walks, as well as organizational practices like New Ways of Working and self-compassion interventions. The lab investigates how these approaches influence mental well-being, work-life balance, and psychological resilience, especially in occupational and academic settings. Their work emphasizes evidence-based, systematic reviews and meta-analyses to evaluate the methodological quality and effectiveness of mental health interventions.

Abstract Shinrin-yoku, immersing oneself in nature using one’s senses, has been receiving increased attention internationally. While most of the existing studies have focused on physical health, this systematic review and meta-analysis examined the mental health impacts of shinrin-yoku, using the PRISMA guidelines (PROSPERO registry: BLINDED). Of 497 articles retrieved on databases including PubMed/MEDLINE, PsycINFO, Science Direct and Google Scholar, twenty met the inclusion criteria. All studi
Although the importance of work-life balance (WLB) is related to occupational psychological outcomes in many countries and industries, these relationships have not been explored in UK construction industry, a major sector of the UK economy. This workforce suffers from high rates of mental health problems and low help-seeking. Accordingly, the purposes of this study were to explore relationships between WLB, mental health, attitudes towards mental health problems, along with work schedules. One h
Digitalization of knowledge work is essential for today's organizations, responding to diversified employee needs. Many organizations are already implementing some form of flexibility to help workers perform work and non-work duties, while maintaining high productivity. While these changes in workplaces, "New Ways of Working (NWW)", have been discussed in the literature, a systematic appraisal of evidence of NWW has not been conducted. Relating to poor work-related mental health worldwide, this
Self-compassion, sharing some commonalities with positive psychology 2.0 approaches, is associated with better mental health outcomes in diverse populations, including workers. Due to the COVID-19 pandemic, there is heightened awareness of the importance of self-care for fostering mental health at work. However, evidence regarding the applications of self-compassion interventions in work-related contexts has not been systematically reviewed to date. Therefore, this systematic review aimed to syn
Academic motivation is recognised as a key factor for academic success and wellbeing. Highly motivated students actively engage with academic activities and maintain good wellbeing. Despite the importance of motivation in education, its relationship with engagement and wellbeing remains to be evaluated. Accordingly, this study explored the relationships between motivation, engagement, self-criticism and self-compassion among UK education postgraduate students. Of 120 postgraduate students approa
Purpose The primary purpose of this descriptive study was to compare the levels of, and relationships among mental health problems, mental health shame, self-compassion, work engagement and work motivation between workers in Japan (collectivistic and success-driven culture) and the Netherlands (individualistic and quality-oriented culture). Design/methodology/approach A cross-sectional design, where convenience samples of 165 Japanese and 160 Dutch workers completed self-report measures about me
The benefits of nature for our health have been an increasing research focus in recent years. In the context of a global increase in mental health diagnoses, the potential health benefits of nature have attracted attention. One practical nature treatment is to walk in nature. However, evidence for this practice on mental health has not been comprehensively appraised to date. This systematic review synthesized the effects of nature walks for depression and anxiety, and evaluated the methodologica
Abstract Poor mental health of university students is becoming a serious issue in many countries. Malaysia - a leading country for Asia-Pacific education - is one of them. Despite the government’s effort to raise awareness, Malaysian students’ mental health remains challenging, exacerbated by the students’ negative attitudes towards mental health (mental health attitudes). Relatedly, self-compassion and resilience have been reported to improve mental health and mental health attitudes. Malaysian
Abstract Malaysia plays a key role in education of the Asia Pacific, expanding its scholarly output rapidly. However, mental health of Malaysian students is challenging, and their help-seeking is low because of stigma. This study explored the relationships between mental health and positive psychological constructs (academic engagement, motivation, self-compassion, and well-being), and evaluated the relative contribution of each positive psychological construct to mental health in Malaysian stud
The COVID-19 pandemic has negatively impacted the mental health of healthcare workers in many countries including Japan. While many survey-based findings have reported the serious state of their wellbeing among healthcare workers, the first-hand experience of the mental health and coping in this population remains to be evaluated. Accordingly, this study aimed to appraise them using constructionist thematic analysis on semi-structured interviews attended by a purposive and snowball sample of 24
Though negative impacts of COVID-19 on occupational mental health have been reported, the mental health of psychotherapists has not been evaluated in depth. As this occupational group treats ever-increasing mental health problems, it is essential to appraise key factors for their mental health. Accordingly, this study aimed to explore burnout of professional psychotherapists. A total of 110 participants completed self-report measures regarding burnout, self-compassion, work-life balance and tele
There is growing awareness of mental health problems among UK business students, which appears to be exacerbated by students’ attitudes of shame toward mental health. This study recruited 138 UK business students and examined the relationship between mental health and shame, and mental health and potential protective factors such as self-compassion and motivation. A significant correlation between each of the constructs was observed and self-compassion was identified as an explanatory variable f
This study aimed to examine the relationships between mental wellbeing and positive psychological constructs in therapeutic students (psychotherapy and occupational therapy students). The number of therapeutic students has increased recently; however, they suffer from poor mental health, which may be improved by potentiating their positive psychological constructs, bypassing mental health shame. Therapeutic students (<i>n</i> = 145) completed measures regarding positive psychological constructs,
The current pandemic of the coronavirus disease 2019 (COVID-19) has negatively impacted medical workers' mental health in many countries including Japan. Although research identified poor mental health of medical workers in COVID-19, protective factors for their mental health remain to be appraised. Accordingly, this study aimed to investigate relationships between mental health problems, loneliness, hope and self-compassion among Japanese medical workers, and compare with the general population
