First get three days\u2019 worth solidly in place, then expand to a week if you have the capacity.<\/p>\n<h3 id=\"q2-1\">Q2: How much do stockpiled foods cost per person?<\/h3>\n<p>About 3,000\u20135,000 yen for three days is the guide. Choose 5-year-storage foods and the annual cost is around 600\u20131,000 yen per person. Rolling-stock dried vegetables can be handled as employee-benefit expenses, so the dedicated stockpiling cost can be held down even further.<\/p>\n<h3 id=\"q3\">Q3: Do stockpiles matter even for a tenant office?<\/h3>\n<p>Yes. There are cases where the building as a whole has stockpiles, but stockpiles for each tenant company are also recommended. Food in particular requires consideration of individual preferences and allergies, so preparing your own gives peace of mind.<\/p>\n<h3 id=\"q4\">Q4: Do stockpiled foods need to accommodate allergies?<\/h3>\n<p>If any employees have allergies, you should prepare accommodating items. Many dried vegetables have vegetables as their only ingredient and contain no major allergens (wheat, egg, dairy, etc.), making them excellent as allergy-friendly foods.<\/p>\n<h3 id=\"q5\">Q5: Is there a legal obligation to stockpile?<\/h3>\n<p>In principle there\u2019s no legal obligation, but in Tokyo the \u201cOrdinance on Measures for Stranded Commuters\u201d sets a best-effort obligation for businesses to keep three days\u2019 worth of stockpiles. In other regions too, BCP-development guidelines recommend stockpiling.<\/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\/storage-shelf-life\/\">How to Store Dried Vegetables and Their Shelf Life | Tips After Opening, Explained<\/a> \/ <a href=\"https:\/\/agriture.jp\/en\/sustainable\/fairtrade-2025\/\">A sustainable future achieved by rethinking fair-trade consumption<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>\u3053\u306e\u8a18\u4e8b\u3067\u308f\u304b\u308b\u3053\u3068 \u5185\u95a3\u5e9c\u63a8\u5968\u306b\u57fa\u3065\u304f\u5f93\u696d\u54e11\u4eba\u3042\u305f\u308a\u306e\u5099\u84c4\u5fc5\u8981\u91cf \u54c1\u76ee\u5225\u306e\u9078\u5b9a\u57fa\u6e96\u3068\u5fc5\u8981\u6570\u91cf\u306e\u8a08\u7b97\u65b9\u6cd5 \u898b [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","meta":{"_acf_changed":false,"swell_btn_cv_data":"","footnotes":"","ssp_meta_description":"\u5185\u95a3\u5e9c\uff08\u9632\u707d\u62c5\u5f53\uff09\u306e\u30ac\u30a4\u30c9\u30e9\u30a4\u30f3\u3067\u306f\u3001\u4f01\u696d\u306b\u5bfe\u3057\u3066 \u5f93\u696d\u54e11\u4eba\u3042\u305f\u308a\u6700\u4f4e3\u65e5\u5206\u306e\u5099\u84c4 \u3092\u63a8\u5968\u3057\u3066\u3044\u307e\u3059\u3002\u9996\u90fd\u76f4\u4e0b\u5730\u9707\u5bfe\u7b56\u5927\u7db1\u3067\u306f\u3001\u767a\u707d\u5f8c3\u65e5\u9593\u306f\u6551\u52a9\u30fb\u6551\u51fa\u6d3b\u52d5\u304c\u6700\u512a\u5148\u3068\u3055\u308c\u308b\u305f\u3081\u3001\u305d\u306e\u9593\u306f\u5916\u90e8\u304b\u3089\u306e\u652f\u63f4\u306b\u983c\u308c\u306a\u3044\u524d\u63d0\u3067\u5099\u3048\u308b\u5fc5\u8981\u304c\u3042\u308a\u307e\u3059\u3002","ssp_meta_keyword":"\u4f01\u696d\u306e\u9632\u707d\u5099\u84c4\u30ea\u30b9\u30c8\u5b8c\u5168\u7248","ssp_meta_canonical":"","ssp_meta_robots":"","ssp_meta_title":""},"categories":[39],"tags":[86,31],"vegetable":[],"class_list":["post-1823","sustainable","type-sustainable","status-publish","format-standard","hentry","category-sustainability","tag-office","tag-health-management"],"acf":{"summary":"\u4f01\u696d\u306e\u9632\u707d\u5099\u84c4\u30ea\u30b9\u30c8\u3068\u3057\u3066\u3001\u5185\u95a3\u5e9c\u63a8\u5968\u306e\u5f93\u696d\u54e11\u4eba\u3042\u305f\u308a3\u65e5\u5206\u5099\u84c4\u3092\u57fa\u6e96\u306b\u3001\u98f2\u6599\u6c349L\u30fb\u4e3b\u98df9\u98df\u30fb\u4e7e\u71e5\u91ce\u83dc6\u301c9\u888b\u30fb\u7f36\u8a703\u301c6\u7f36\u3068\u3044\u3046\u5177\u4f53\u7684\u306a\u5fc5\u8981\u91cf\u3092\u89e3\u8aac\u3057\u307e\u3059\u3002\u30a2\u30eb\u30d5\u30a1\u7c73\u30fb\u4e7e\u30d1\u30f3\u30fb\u7f36\u8a70\u30d1\u30f3\u306e\u9078\u5b9a\u57fa\u6e96\u3001\u898b\u843d\u3068\u3055\u308c\u304c\u3061\u306a\u91ce\u83dc\u5099\u84c4\u306e\u91cd\u8981\u6027\u3001\u30ab\u30bb\u30c3\u30c8\u30b3\u30f3\u30ed\u3084\u7c21\u6613\u30c8\u30a4\u30ec\u7b49\u306e\u751f\u6d3b\u7528\u54c1\u3001\u5206\u6563\u4fdd\u7ba1\u3068\u5e741\u56de\u68da\u5378\u3057\u306e\u7ba1\u7406\u30dd\u30a4\u30f3\u30c8\u309250\u4eba\u898f\u6a21\u306e\u8a08\u7b97\u4f8b\u4ed8\u304d\u3067\u7d39\u4ecb\u3057\u307e\u3059\u3002","product":null},"_links":{"self":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable\/1823","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable"}],"about":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/types\/sustainable"}],"author":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/comments?post=1823"}],"version-history":[{"count":0,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/sustainable\/1823\/revisions"}],"wp:attachment":[{"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/media?parent=1823"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/categories?post=1823"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/tags?post=1823"},{"taxonomy":"vegetable","embeddable":true,"href":"https:\/\/agriture.jp\/en\/wp-json\/wp\/v2\/vegetable?post=1823"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
