I am summarizing government-released statistical information. For more detailed data, please refer to the government statistics portal (e-Stat) or the statistics data published by respective ministries and agencies.

Isolation at the workplace based on occupation: Frequency of direct conversation is highest among students and corporate executives. Lowest among the unemployed.

Regular Employees vs. Non-Regular Employees: The frequency of direct conversation 4 to 5 times a week is 15.8% among regular employees and 14.2% among non-regular employees, showing relatively similar trends. The frequency of less than once a week is higher, especially among non-regular employees, at 18.0%. Those in stable positions tend to have a lower frequency of less than once a week and relatively higher frequencies of direct conversation.

Company Executives and Self-Employed Individuals: Company executives and self-employed individuals exhibit relatively high frequencies of direct conversation 4 to 5 times a week at 22.9% and 18.3%, respectively. Self-employed individuals also show a higher frequency of 2 to 3 times a week at 14.1%. Executives and self-employed individuals tend to engage in more work-related communication.

Students: Students demonstrate an overwhelmingly high frequency of direct conversation 4 to 5 times a week at 62.3%, with other frequencies being lower. Students often engage in communication with various individuals through academic and school-related activities, particularly with a significant emphasis on the 4 to 5 times a week frequency.

Unemployed and Jobless Individuals: Both unemployed and jobless individuals exhibit a relatively high frequency of about once a week. The unemployed also show higher frequencies of 2 to 3 times a week and less than once a month, potentially indicating a temporary reduction in communication.

Other Occupations: Individuals in other occupations show a relatively higher frequency of 2 to 3 times a week. Frequencies of 4 to 5 times a week are somewhat higher, while frequencies of less than once a month are relatively lower.

Overall, there are differences in the frequency of direct conversation based on occupation and gender. Students, executives, and self-employed individuals tend to show relatively higher communication frequencies, while unemployed or jobless individuals potentially exhibit lower frequencies. Understanding how occupational circumstances impact feelings of isolation requires consideration of social factors and situations.
