A famous open-air bath that can accommodate 200 people at once, located along the Ichido River flowing near Zao Onsen town. There are two women's baths in the upstream section of the river and two men's baths in the downstream section, separated by changing rooms. Both baths are made of large stone formations, providing a rustic and liberating open-air experience. The hot spring, with a source temperature of about 51\u00b0C, is a strongly acidic sulfur spring known as \"beauty-making water,\" with the source water flowing directly into the bath. From June to October, there is a special operation of the \"Night Large Open-Air Bath,\" which is full of charm, so be sure to check it out.<\/p>","protected":false},"author":9,"featured_media":194250,"template":"","meta":{"_acf_changed":false,"ep_exclude_from_search":false},"categories":[75],"tags":[],"class_list":["post-269910","travelpost","type-travelpost","status-publish","has-post-thumbnail","hentry","category-spot"],"blocksy_meta":{"styles_descriptor":{"styles":{"desktop":"","tablet":"","mobile":""},"google_fonts":[],"version":8}},"acf":[],"_links":{"self":[{"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/travelpost\/269910","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/travelpost"}],"about":[{"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/types\/travelpost"}],"author":[{"embeddable":true,"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/users\/9"}],"version-history":[{"count":0,"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/travelpost\/269910\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/media\/194250"}],"wp:attachment":[{"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/media?parent=269910"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/categories?post=269910"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.allway-japan.com\/en\/wp-json\/wp\/v2\/tags?post=269910"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
