That\u2019s far larger than absenteeism (loss from taking sick leave). That\u2019s because presenteeism affects all employees a little at a time and, being \u201cinvisible,\u201d tends to get put on the back burner.<\/p>\n<p>In a Ministry of Economy, Trade and Industry survey, the loss from presenteeism is estimated at<strong>about 600,000\u2013800,000 yen per person a year<\/strong>. For a company of 50 people, that\u2019s 30\u201340 million yen a year.

A guideline of 60,000\u201370,000 yen a month and up.<\/p>\n<h3 id=\"3\">Method 3: Meal-Subsidy Programs (Vouchers, E-Money)<\/h3>\n<p>A method of letting employees use nearby restaurants with meal vouchers or e-money. With the FY2026 tax reform, the tax-free allowance is expected to expand to 7,500 yen a month.<\/p>\n<h3 id=\"4_1\">Method 4: Nutrition Education and Food-Education Events<\/h3>\n<p>Regularly hold seminars by registered dietitians and introduce healthy menus. An approach that changes employees\u2019 eating behavior from the knowledge side.<\/p>\n<h2 id=\"_8\">How to Measure the Effect of Food Measures<\/h2>\n<p>\u201cWe introduced the measure but we don\u2019t know if it worked\u201d is a problem, isn\u2019t it?

Being self-assessment there is bias, but it\u2019s perfectly usable for tracking change over time and comparing before and after a measure.<\/p>\n<h3 id=\"q2\">Q2: Are there causes of presenteeism other than diet?<\/h3>\n<p>Of course. Lack of sleep, mental health, allergies, and back and shoulder pain are also major factors. That said, because diet indirectly affects all these factors, it can be called the most fundamental measure.<\/p>\n<h3 id=\"q3\">Q3: How long until food measures show an effect?<\/h3>\n<p>\u500b\u4eba\u5dee\u306f\u3042\u308a\u307e\u3059\u304c\u3001\u98df\u7fd2\u6163\u3092\u898b\u76f4\u3057\u305f\u52b9\u679c\u306f2\u301c4\u9031\u9593\u3067\u4f53\u611f\u3059\u308b\u4eba\u304c\u591a\u3044\u3067\u3059\u3002\u7d44\u7e54\u5168\u4f53\u306e\u30c7\u30fc\u30bf\u3068\u3057\u3066\u6709\u610f\u5dee\u304c\u51fa\u308b\u306e\u306f\u30013\u301c6\u304b\u6708\u304c\u76ee\u5b89\u3067\u3059\u3002<\/p>\n<h3 id=\"q4\">Q4: Can you really get nutrition from dried vegetables?<\/h3>\n<p>Dried vegetables retain nutrients such as dietary fiber, minerals, and vitamins A and E almost intact. Eating 350 g of fresh vegetables every day is ideal, but for people who find that hard in practice, dried vegetables are an easy supplementary means.<\/p>\n<h3 id=\"q5\">Q5: Do even small companies need presenteeism measures?<\/h3>\n<p>If anything, smaller companies need them more. If one person out of ten sees a performance drop, the impact on the whole is far greater than at a large company. Setting out dried vegetables can be started from around 10,000 yen a month, so give it a try first.<\/p>\n\n\n\n\n\n<h3 class=\"wp-block-heading\">Recommended reading<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/agriture.jp\/en\/sustainable\/\">Sustainable initiatives<\/a> \/ <a href=\"https:\/\/agriture.jp\/en\/oem\/\">Commercial dried vegetables<\/a> \/ <a href=\"https:\/\/agriture.jp\/en\/product\/\">Product lineup<\/a> \/ <a href=\"https:\/\/agriture.jp\/en\/sustainable\/veg-dashi\/\">What is vegetable dashi?
