However, their direct use is limited to local areas due to difficulties in transport and long-term storage.<br>This is where <strong>onsen concentration technology<\/strong> plays an essential role. So, how exactly is onsen water concentrated?<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">1. <strong>Thermal Evaporation Method<\/strong><\/h3>\n\n\n\n<p>Onsen water is heated to evaporate its water content, leaving behind concentrated minerals. This is a relatively simple approach, but some minerals can be sensitive to heat, so careful control is needed to preserve their qualities.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Membrane Concentration (Reverse Osmosis) Method<\/strong><\/h3>\n\n\n\n<p>Using special membranes, water is separated from the minerals and active components, concentrating them effectively. Since this method works at low temperatures, it helps retain the natural properties of the original onsen water.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>Cryoconcentration (Freezing) Method<\/strong><\/h3>\n\n\n\n<p>By cooling and partially freezing the onsen water, water molecules are separated and removed. This approach prevents heat-related deterioration and preserves the unique qualities of each spring.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">4. <strong>Combination with Powdering Techniques<\/strong><\/h3>\n\n\n\n<p>Further drying the concentrated onsen water into powder improves its storage stability and portability. This makes it ideal for products such as bath salts and cosmetics, expanding its use in global markets.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">\u2705 <strong>Conclusion<\/strong><\/h3>\n\n\n\n<p>Onsen concentration methods are the <strong>key to sharing Japan\u2019s healing culture with the world<\/strong>.<br>By using advanced technologies, Japan can protect its onsen heritage while opening up new domestic and international opportunities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u2668\ufe0f \u65e5\u672c\u306e\u6e29\u6cc9\u306e\u6fc3\u7e2e\u65b9\u6cd5\u306b\u3064\u3044\u3066 \u65e5\u672c\u304c\u8a87\u308b\u6e29\u6cc9\u306f\u3001\u8c4a\u5bcc\u306a\u30df\u30cd\u30e9\u30eb\u3068\u81ea\u7136\u306e\u6075\u307f\u304c\u8a70\u307e\u3063\u305f\u300c\u7652\u3057\u306e\u8cc7\u6e90\u300d\u3067\u3059\u3002\u3057\u304b\u3057\u3001\u305d\u306e\u307e\u307e\u3067\u306f\u8f38\u9001\u3084\u9577\u671f\u4fdd\u5b58\u304c\u96e3\u3057\u304f\u3001\u73fe\u5730\u3067\u3057\u304b\u697d\u3057\u3081\u306a\u3044\u306e\u304c\u8ab2\u984c\u3067\u3057\u305f\u3002\u305d\u3053\u3067\u6ce8\u76ee\u3055\u308c\u3066\u3044\u308b\u306e\u304c\u300c\u6e29\u6cc9 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":117,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[82],"tags":[222,153,152,150,223,148,145,174,147,221,142,144,140,137,219,218,135,141,220,139],"class_list":["post-115","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-82","tag-concentratedonsen","tag-futureofonsen","tag-highconcentrationonsen","tag-hotspringessence","tag-hotspringresearch","tag-japaneseinnovation","tag-onsenconcentration","tag-onseninnovation","tag-onsenscience","tag-onsentechnology","tag-142","tag-144","tag-140","tag-137","tag-219","tag-218","tag-135","tag-141","tag-220","tag-139"],"_links":{"self":[{"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/posts\/115","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=115"}],"version-history":[{"count":2,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/posts\/115\/revisions"}],"predecessor-version":[{"id":118,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/posts\/115\/revisions\/118"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=\/wp\/v2\/media\/117"}],"wp:attachment":[{"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=115"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=115"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/onsenfudousan.jp\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=115"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
