Opportunity Loss from Stiff Shoulders and Back Pain Estimated at Over 500 Million Yen Annually for a 1,000-Employee Company! Survey Reveals 93.4% Experience Daily Decline in Concentration

Well Body Inc. (Headquarters: Minato-ku, Tokyo; Representatives: Junichi Mizuno and Naoto Yoshimura), which provides corporate physical care service "Offi-Stretch®", conducted a survey titled "Fact-Finding Survey on Physical Fatigue and Workplace Conditions" targeting 152 business professionals nationwide. As the fourth in a series of surveys, this installment focuses on the impact of physical discomfort on corporate productivity. Survey Summary: 93.4% of respondents reported some loss of concentration during the day, averaging 44.5 minutes per day. Based on this, Well Body estimates that for a company with 1,000 employees, annual opportunity loss could exceed 500 million yen, an invisible cost not reflected in financial statements. Calculation: Using 44.5 minutes lost per day, 240 working days per year, and an hourly wage of 3,109 yen (based on average annual salary of 5.45 million yen for regular employees from NTA survey), estimated losses are: 300 employees: ~170 million yen; 500: ~280 million; 1,000: ~550 million; 3,000: ~1.66 billion yen. Note: This is an estimate based on subjective reports, not actual financial loss. Survey Results: Only 6.6% reported "always able to concentrate". Breakdown: almost 0 min: 6.6%; 15–30 min: 46.7%; about 1 hour: 36.8%; 2 hours or more: 9.9%. The 2+ hours group corresponds to over 25% of work time affected. Previous survey showed sales/customer service roles had worst average loss (55.5 min/day). Presenteeism: The concept of working while impaired by physical or mental issues, which is invisible in attendance records and financial statements. Mizuno: Chronic stiffness and pain are often normalized; there is a gap between employee discomfort and management awareness. Survey details available for free download.
