This industrial heritage site, which operated from the Taish\u014d era through the wartime and postwar periods, is now used as a roadway while remaining a tourist spot that combines unique beauty with a sense of historical romance.<\/p>\n\n\n\n<p>The continuous row of concrete pillars creates a mysterious and strikingly beautiful scene, making it a photogenic location that has gained increasing attention in recent years.<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"spot-middle-banner-image\"><img decoding=\"async\" src=\"https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611483_m-1.webp\"\/><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"highlights-of-the-higashi-akadani-continuous-tunnel\"><span class=\"ez-toc-section\" id=\"Highlights_of_the_Higashi-Akadani_Continuous_Tunnel\"><\/span>Highlights of the Higashi-Akadani Continuous Tunnel<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The greatest appeal of the Higashi-Akadani Continuous Tunnel is its scenery that looks \u201cjust like the corridor of an ancient temple.\u201d Concrete pillars stand evenly spaced, and the light streaming through the arched ceiling changes in appearance depending on the time of day and season. In spring when the fresh greens emerge, or in autumn when the leaves turn vibrant colors, green and golden light filters into the tunnel, allowing visitors to capture magical, atmospheric photos.<\/p>\n\n\n\n<p>Inside the tunnel, the quiet and cool air makes it feel completely isolated from the outside world, giving you an extraordinary sensation as if you have wandered into another realm. The pitch-black soot remaining on the ceiling is evidence that steam locomotives once passed through here, offering a tangible sense of the region\u2019s industrial history.<\/p>\n\n\n\n<p>After being laid in the Taish\u014d era, this dedicated railway line experienced closures due to economic downturns\u2014earning the nickname \u201cAkarabi Line\u201d\u2014before being extended to Higashi-Akadani and reopened during World War II to meet rising military demand. Beyond the end of the tunnel lies the abandoned, rust-colored truss bridge \u201cIide River Bridge,\u201d once an important structure of the mining railway. Set against the deep green valley, it creates a striking and somewhat melancholic yet beautiful contrast.<\/p>\n\n\n\n<p><\/p>\n\n\n  <div class=\"spot-nearby-attractives\">\n    <div class=\"spot-nearby-attractives__list\">\n              <div class=\"spot-nearby-attractives__item\">\n          <div class=\"item-col\" data-offer=\"1\">\n            <img decoding=\"async\" src=\"https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/30115085_m.webp\" alt=\"\">\n          <\/div>\n        <\/div>\n\n        <div class=\"spot-nearby-attractives__item-modal\" data-offer=\"1\">\n          <div class=\"spot-nearby-attractives__item-modal__content\">\n            <div class=\"spot-nearby-attractives-image\">\n                <img decoding=\"async\" src=\"https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/30115085_m.webp\" alt=\"\">\n            <\/div>\n            <div class=\"nearby-attractives-comment\">\n              <div class=\"nearby-attractives-comment__author\">\n                <img decoding=\"async\" src=\"https:\/\/secure.gravatar.com\/avatar\/1ebc84b96fb57dd37b41610382576f2aa5dcbd37fd157d7a6ab3c6cffb8ca21d?s=96&#038;d=mm&#038;r=g\" alt=\"\">\n                <span>OsakiYohei<\/span>\n              <\/div>\n              <p class=\"nearby-attractives-comment__desc\">Higashi-Akadani Continuous Tunnel<\/p>\n            <\/div>\n          <\/div>\n        <\/div>\n              <div class=\"spot-nearby-attractives__item\">\n          <div class=\"item-col\" data-offer=\"2\">\n            <img decoding=\"async\" src=\"https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/28216132_m.webp\" alt=\"\">\n          <\/div>\n        <\/div>\n\n        <div class=\"spot-nearby-attractives__item-modal\" data-offer=\"2\">\n          <div class=\"spot-nearby-attractives__item-modal__content\">\n            <div class=\"spot-nearby-attractives-image\">\n                <img decoding=\"async\" src=\"https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/28216132_m.webp\" alt=\"\">\n            <\/div>\n            <div class=\"nearby-attractives-comment\">\n              <div class=\"nearby-attractives-comment__author\">\n                <img decoding=\"async\" src=\"https:\/\/secure.gravatar.com\/avatar\/1ebc84b96fb57dd37b41610382576f2aa5dcbd37fd157d7a6ab3c6cffb8ca21d?s=96&#038;d=mm&#038;r=g\" alt=\"\">\n                <span>OsakiYohei<\/span>\n              <\/div>\n              <p class=\"nearby-attractives-comment__desc\">The moment light pierces through the Higashi-Akadani Continuous Tunnel<\/p>\n            <\/div>\n          <\/div>\n        <\/div>\n          <\/div>\n  <\/div>\n  \n\n\n\n<div class=\"wp-block-liquid-speech-balloon liquid-speech-balloon-wrap liquid-speech-balloon-00\"><div class=\"liquid-speech-balloon-avatar\"><\/div><div class=\"liquid-speech-balloon-text\"><p>The sight of light streaming through the gaps between the pillars is magical.<\/p><div class=\"liquid-speech-balloon-arrow\"><\/div><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-enjoy-your-time-at-the-higashi-akadani-continuous-tunnel\"><span class=\"ez-toc-section\" id=\"How_to_Enjoy_Your_Time_at_the_Higashi-Akadani_Continuous_Tunnel\"><\/span>How to Enjoy Your Time at the Higashi-Akadani Continuous Tunnel<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Popular among young travelers as an \u201cInstagram-worthy spot,\u201d the Higashi-Akadani Continuous Tunnel allows you to take photos that look like scenes from a movie, depending on your framing and the way the light falls. Especially popular are shots taken with the valley in the background through the pillars, or capturing the exact moment when sunlight streams into the tunnel. If you look down through the gaps between the pillars, you can overlook the vivid blue-green and emerald waters of the Kajigawa (Iide River) flowing through the valley.<\/p>\n\n\n\n<p>Today, the continuous tunnel is used as part of Niigata Prefectural Route 335, and you can actually drive through it. Among the four tunnels, the longer sections have narrow lanes, so one-way alternating traffic is controlled by traffic signals at several points. This makes the drive surprisingly thrilling, giving you a feeling almost like being the operator of a train.<\/p>\n\n\n\n<p>Beyond the tunnel, remnants such as the Iide River Bridge\u2014an old truss railway bridge\u2014and former station sites of the old Akadani Line are scattered throughout the area. It is also possible to enjoy cycling or hiking along these routes as a \u201cpathway for exploring history.\u201d For those interested in railway heritage or industrial history, this is a truly irresistible place to visit.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large is-style-vk-image-photoFrame-tilt-left\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"685\" data-id=\"1908\" src=\"http:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611488_m-1024x685.webp\" alt=\"\" class=\"wp-image-1908\" srcset=\"https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611488_m-1024x685.webp 1024w, https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611488_m-768x514.webp 768w, https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611488_m-1536x1027.webp 1536w, https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611488_m-1x1.webp 1w, https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/12\/24611488_m.webp 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"basic-information\"><span class=\"ez-toc-section\" id=\"Basic_Information\"><\/span>Basic Information<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Spot Name\uff1aHigashi-Akadani Continuous Tunnel (Niigata Prefectural Route 335 Takiya\u2013Kami-Akadani Line)<\/p>\n\n\n\n<p>Open hours\/Closed days \uff1aClosed during winter (December\u2013April) due to road restrictions<\/p>\n\n\n\n<p>Fees\uff1aFree (open for passage)<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"access\"><span class=\"ez-toc-section\" id=\"Access\"><\/span>Access<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<iframe src=\"https:\/\/www.google.com\/maps\/embed?pb=!1m18!1m12!1m3!1d3151.9149440194037!2d139.4678118753163!3d37.815461209816185!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x5f8ad5007689bb97%3A0xefa40b8d3c41681d!2z5p2x6LWk6LC36YCj57aa5rSe6ZaA!5e0!3m2!1sja!2sjp!4v1766044731212!5m2!1sja!2sjp\" width=\"600\" height=\"450\" style=\"border:0;\" allowfullscreen=\"\" loading=\"lazy\" referrerpolicy=\"no-referrer-when-downgrade\"><\/iframe>\n\n\n\n<p>Adress\uff1aTakiya, Shibata City, Niigata Prefecture, Japan<\/p>\n\n\n\n<p>Access\uff1aAbout 40 minutes by car from the Nihonkai-Tohoku Expressway \u201cSeiro-Shibata IC\u201d<\/p>\n\n\n\n<p>Parking\uff1aNone<\/p>\n\n\n\n<p><em>*Roadside parking is possible, but please be careful not to obstruct traffic.<\/em><\/p>\n\n\n<div class=\"pickup-ryokan-banner\" style=\"background-image: url(https:\/\/ryokan-book.com\/en\/wp-content\/uploads\/2025\/11\/Ne_226_PR-2-scaled.webp);\">\n        <div class=\"pickup-ryokan-wrapper\">\n            <div class=\"pickup-ryokan-banner-header\">\n                <h2><span class=\"ez-toc-section\" id=\"Recommended_Nearby_Ryokans\"><\/span>Recommended Nearby Ryokans<span class=\"ez-toc-section-end\"><\/span><\/h2>\n            <\/div>\n            <div class=\"pickup-ryokan-info\">\n                <div class=\"pickup-ryokan-titleset\">\n                    <h3 class=\"pickup-ryokan-name\"><span class=\"ez-toc-section\" id=\"Ne\"><\/span>N\u00e9<span class=\"ez-toc-section-end\"><\/span><\/h3>\n                    <p class=\"pickup-ryokan-description\">Auberge \u2018N\u00e9\u2019 opened in October 2025 in Shibata City, Niigata Prefecture, as an exclusive one-group-per-day stay-and-dine experience.
