With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here. I look forward to your continued support.","sameAs":["http:\/\/enta-d.co.jp\/","https:\/\/www.facebook.com\/norimenman\/","https:\/\/www.instagram.com\/enta.d\/","https:\/\/x.com\/norimenman","https:\/\/www.youtube.com\/c\/entadnorimenman"]},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/norimen.net\/lifeline-rope-rebar-friction\/#local-main-organization-logo","url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","contentUrl":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2016\/10\/site_title_logo.png","width":220,"height":50,"caption":"\u65b0\u30a8\u30f3\u30bf\u306e\u6cd5\u9762\u7ba1\u7406\u587e"}]}},"jetpack_likes_enabled":true,"jetpack_sharing_enabled":true,"publishpress_future_action":{"enabled":false,"date":"2026-08-21 15:35:47","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category","extraData":[]},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"jetpack_featured_media_url":"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2021\/04\/50d69730bc22d76e71e8f3502c6f2e1a.jpg","_links":{"self":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/43964","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/comments?post=43964"}],"version-history":[{"count":1,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/43964\/revisions"}],"predecessor-version":[{"id":61898,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/posts\/43964\/revisions\/61898"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media\/43978"}],"wp:attachment":[{"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/media?parent=43964"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/categories?post=43964"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/norimen.net\/en\/wp-json\/wp\/v2\/tags?post=43964"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
