Objectives: The aim of this review was to summarize the lessons learned from the experience in protecting the health of workers engaged in operations following the accident at the Fukushima Daiichi Nuclear Power Plant (NPP). Methods: We reviewed all types of scientific papers examining workers’ health found in Medline and Web of Sciences as well as some official reports published by the Ministry of Health, Labour and Welfare of Japan and other governmental institutes. Results: The papers and reports were classified into those investigating workers at the Fukushima Daiichi and Daini NPPs workers engaged in decontamination operations in designated areas, and other workers. Regarding workers at the NPPs, many efforts were made to establish an emergency-care and occupational health system. Risk management efforts were undertaken for radiation exposure, heat stress, psychological stress, outbreak of infectious diseases, and fitness for work. Only a few reports dealt with decontamination workers and others; however, the health management of these workers was clearly weaker than that for workers at the NPPs. Conclusions: Many lessons can be learned from what occurred. That knowledge can be applied to ongoing decommissioning work and to future disasters. In addition, it is necessary to study the long-term health effects of radiation exposure and to accumulate data about the health of workers engaged in decontamination work and other areas.

Objectives: To elucidate the factors that influence occupational physicians’ decision to issue an employer warning.Methods: The interview was conducted with 10 Japan Society for Occupational Health certified occupational physicians (COPs) and certified senior occupational physicians (CSOPs) to create nine fictive scenarios in which an occupational physician may need to consider issuing a warning. Sixteen CSOPs assessed the seriousness of the problem in each of nine scenarios where they may need to consider issuing an employer warning. Next, using a survey questionnaire, 597 COPs and CSOPs were asked to rate how likely they were to issue a warning in each of the nine scenarios, and answer items on their characteristics and number of previously issued warnings. A multilevel logistic regression analysis nested for various scenarios was used to assess the odds ratio (OR) of being likely to issue a warning.Results: Valid questionnaires were obtained from 117 participants (19.6%). The ORs and 95% confidence intervals (CIs) were as follows: mean score of seriousness of the problem, 5.90 (4.50-7.75); years of experience as occupational physician, 1.04 (1.02-1.06); women, 1.75 (1.20-2.54); being a part-time occupational physician without in-house experience, 2.08 (1.31-3.29); and having previously issued two or more times warnings, 1.99 (1.29-3.06), compared with those who had never issued a warning.Conclusions: Occupational physicians’ likelihood to issue a warning was associated with the seriousness of the problem as assessed in various scenarios, years of experience as occupational physician, gender, employment type, experience as in-house occupational physician, and number of past warnings.

A nuclear accident occurred at the Fukushima Daiichi Nuclear Power Plant of Tokyo Electric Power Company (TEPCO) as a result of a mega-earthquake and tsunami in March, 2011. A large number of workers were engaged in response and recovery operations under a complex structure of involved companies. They were exposed not only to radiation but also to other health hazards. TEPCO implemented programs to prevent radiation exposure, but had no effective systems for managing the other health risks and few occupational health (OH) professionals contributed to the health risk management. The University of Occupational and Environmental Health (UOEH), Japan, dispatched physicians to a quake-proof building at the plant t provide first-aid services from mid-May, 2011, and took a strategic approach to protecting workers’ from existing health risks. UOEH presented recommendations on OH systems and preventive measures against heat stress to the Government and TEPCO. The Ministry of Health, Labour, and Welfare issued guidelines to TEPCO and contractors. TEPCO implemented a comprehensive program against heat stress according to the guidelines and in cooperation with UOEH. As a result, we successfully prevented severe heat illness during summer 2011. From our experiences, we believe that the following recommendations should be considered: 1) the role of OH and the participation of experts should be defined in emergency response plans; 2) regulations should allow the national government and main companies involved to lead safety and health initiatives for all workers at disaster sites; and 3) OH professionals, response manuals and drills should be organized at a national level.

Objectives: The objective of this study was to estimate a risk of cardiovascular and cerebrovascular diseases for each worker and to determine whether this risk is associated with the incidence and costs of presenteeism, absenteeism, and medical/drug treatments.Methods: Established risk equations were used to estimate the 10-year probability of developing coronary artery disease and ischemic stroke in male workers aged 40-65 years who were recruited from four pharmaceutical companies in Japan. The incidence of presenteeism was defined as existence of presenteeism for the past a month, and the incidence of absenteeism was defined as existence of sick-leave for the past three months by a self-administered questionnaire. Each cost was calculated based on the human capital method. Data on medical/drug treatments were collected from health insurance claims.Results: The risks were calculated for 6047 workers. Individuals at moderate and high risk of coronary artery disease had a significantly higher rate of presenteeism and absenteeism than workers at low risk. Workers at moderate and high risk of ischemic stroke also had a significantly higher rate of presenteeism and absenteeism than workers at low risk. Mean costs for absenteeism and medical/drug treatments increased with the risk of developing coronary artery disease or ischemic stroke, while costs for presenteeism did not.Conclusions: To prevent the costs of presenteeism, workers not only at high risk but also at low and moderate risk of developing cardiovascular and cerebrovascular diseases should receive health care services.

Objectives: The present study examined the relationship between health culture evaluated by the Health and Productivity Survey Sheets and the implementation status of infection control measures against COVID-19 in the workplace.Methods: This was a cross-sectional study using the corporate data (2518 companies) collected for the purpose of selecting the excellent company of health and productivity management by the Japanese government. The explanatory variable was the overall evaluation score, and the outcome was whether or not infection control measures against COVID-19 in the workplace. We used logistic regression analysis and calculated the odds ratio adjusted for the industry sector, the corporation size, and the operating profit ratio by the overall evaluation score category.Results: The odds ratio of all infection control measurements in the workplace increased as the evaluation score increased.Conclusions: This study revealed a new finding that the presence of a healthy culture in the workplace will lead to the appropriate implementation of infection control measures during a pandemic. The company's ordinary commitment to employee health will be effective even in times of health crisis, such as during the outbreak of the pandemic.

An important challenge to occupational health services in Japan is the necessary shift from regulation-based occupational health program to health risk-based program. The Occupational Safety and Health Management System (OSHMS) is an effective tool for introducing risk-based activities. To date, the Five Management system has been used to manage occupational health activities. This classification, however, does not show the interactions among the listed activities. Nor is it clear how this system contributes to the PDCA (Plan/Do/Check/Act) cycle for continual improvement. The category in the Five Management system called “Roles of the Occupational Physician” covers most of the occupational health services required in Japan. The items listed in the Five Management system were compared to the guidelines of OSHMS from the International Labour Office and issues that should be solved for occupational health activities with OSHMS were clarified. Seven issues are discussed in this paper; (1) occupational safety and health policy and audit that can drive the PDCA cycle effectively, (2) reclassification of occupational health activities with several different objectives, (3) set up of targets, (4) risk assessment methods that can prioritize health risks compared to safety risks, (5) exposure assessment methods for risk assessment, (6) flexibility of laws and regulations, and (7) development of talented professionals for risk-based occupational health activities.

This paper reviews the circumstances, current situation, and issues for Japanese occupational health physicians and discusses future developments. The Industrial Safety and Health Act requires workplaces that regularly employ 50 or more workers to appoint one occupational health physician. Their duties have been expanded by amendments to the Act, and they now have increased authority. Under these conditions, the occupational health physicians not only comply with laws and regulations but also follow a professional code of ethics. After the Act was amended in 1996, occupational health physicians had to complete additional training requirements. Basic training courses are provided by the Japan Medical Association (JMA) and the University of Occupational and Environmental Health, Japan. Most of the occupational health physicians certified by the JMA do not spend enough time on occupational health. Many Japanese occupational health work issues can be separated into issues of exposure, labor, and the occupational health system. Occupational health is characterized by changing needs because of new industrial structures and technological innovations. Given occupational health physicians' expanding duties and professional development, they need to collaborate with one other and other occupational health staff to meet society's expectations.

Objectives: In Japan, employee fitness for work is determined by annual medical examinations. It may be possible to reduce the variability in the results of work fitness determination, particularly for situation, if there is consensus among experts regarding consideration of limitation of work by means of a single parameter. Methods: Consensus building was attempted among 104 occupational physicians by employing a 3-round Delphi method. Among the medical examination parameters for which at least 50% of participants agreed in the 3rd round of the survey that the parameter would independently merit consideration for limitation of work, the values of the parameters proposed as criterion values that trigger consideration of limitation of work were sought. Parameters, along with their most frequently proposed criterion values, were defined in the study group meeting as parameters for which consensus was reached. Results: Consensus was obtained for 8 parameters: systolic blood pressure 180 mmHg (86.6%), diastolic blood pressure 110 mmHg (85.9%), postprandial plasma glucose 300 mg/dl (76.9%), fasting plasma glucose 200 mg/dl (69.1%), Cre 2.0mg/dl (67.2%), HbA1c (JDS) 10% (62.3%), ALT 200 U/l (61.6%), and Hb 8 g/l (58.5%). Conclusions: To support physicians who give advice to employers about work-related measures based on the results of general medical examinations of employees, expert consensus information was obtained that can serve as background material for making judgements. It is expected that the use of this information will facilitate the ability to take appropriate measures after medical examination of employees.

Objectives: Presenteeism refers to the condition of working while having health problems and can be one of the perspectives to assess the incompatibility between workers and their jobs. The purpose of this survey was to find out what kind of occupational health issues can be detected by occupational physicians' interviews focusing on presenteeism. Methods: We conducted interviews with workers suffering from presenteeism in a food manufacturing company. The Work Functioning impairment scale (WFun) was used as the indicator of presenteeism. We discussed the occupational health issues and the necessity of additional interventions. Results: Thirty-nine workers with WFun score of 21 or higher were interviewed, and we have found nine cases in need of support. The workplace issues were structured into four categories: (i) health problems that are difficult to identify through health checkups, (ii) health problems missed by the stress check program, (iii) health problems caused by workload that cannot be identified by workplace patrols, and (iv) health problems that are not considered because they do not require support. Conclusions: We discovered new workplace issues by interviewing workers suffering from presenteeism.

Objectives: To identify what types of information were useful and/or difficult to obtain for occupational physicians during the COVID-19 epidemic, and how information should be provided to help occupational physicians in the event of future outbreaks of emerging infectious diseases. Methods: The list was developed by categorizing information about COVID-19 delivered by researchers to a group of occupational physicians after the COVID-19 outbreak. We created a survey and asked the group about the usefulness and ease of obtaining each type of information. Results: In total, 79.1–100% of the occupational physicians said that each type of information was “Useful”. Information on the nature of the virus; clinical course, testing, and treatment; infection prevention measures; regulations in Japan; immigration restrictions in Japan; and guidelines were all considered useful by more than 95%, as was information about the introduction of information aggregation websites by public institutions, academic societies, experts, and others, and sharing of case studies by information distribution group members. These last two items also had a high percentage of respondents who said that they “only obtained the information because it was distributed this way”. Conclusions: Constructing a system for automatic distribution of information that is useful to occupational physicians and difficult to obtain elsewhere may make it easier for occupational physicians to respond more smoothly to emerging infectious disease outbreaks within a company.

Objectives: The working-age population is rapidly declining in Japan, so the government has adopted “health and productivity management” (HPM). This policy initiative aims to encourage corporations to view health promotion activities as an investment in their employees’ health. The objective of this study was to examine the association between organizational factors and knowledge of the organization's effectiveness and program participation levels, and to understand the factors that affect effectiveness of corporations’ activities.Methods: We used data from all corporations that completed the HPM Survey Sheets in 2018 (n = 1800). The explanatory variables were organizational factors: written company-wide policy, agenda item at management-level meetings, regular education for managers, and full-time occupational health staff. The outcome variables were knowledge of the corporation's status on the effectiveness indicators (employees’ exercise habits, risk for high blood pressure, visiting hospital after a health examination, and long-term sickness absences) and rates of participation in four areas (health education, exercise program, dietary program, and influenza vaccination). The associations between organizational factors and knowledge on effectiveness indicators and rates of program participation were analyzed using multiple logistic regression analysis.Results: All the organizational factors were related to knowledge of effectiveness indicators, but only some were associated with the program participation indicators in the model, including all explanatory variables.Conclusion: Enhancing organizational factors may lead to improvement of HPM programs and higher program participation among employees in corporations.

A novel anaerobic heterotrophic strain, designated strain sy52T, was isolated from a hydrothermal chimney at Suiyo Seamount in the Pacific Ocean. A 16S rRNA gene analysis revealed that the strain belonged to the family Petrotogaceae in the phylum Thermotogae. The strain was mesophilic with optimum growth at 48°C and the phylum primarily comprised hyperthermophiles and thermophiles. Strain sy52T possessed unique genomic characteristics, such as an extremely low G+C content and 6 copies of rRNA operons. Genomic analyses of strain sy52T revealed that amino acid usage in the predicted proteins resulted from adjustments to mesophilic environments. Genomic features also indicated independent adaptions to the mesophilic environment of strain sy52T and Mesotoga species, which belong to the mesophilic lineage in the phylum Thermotogae. Based on phenotypic and phylogenetic evidence, strain sy52T is considered to represent a novel genus and species in the family Petrotogaceae with the proposed name Tepiditoga spiralis gen. nov., sp. nov.
