Embark on a Soul-Stirring Journey As Japan’s Gran Tenku Sightseeing Train Take You to Mount Koya Redefining Travel with Luxury, Culture, and Spiritual Immersion Starting April 2026

Japan is set to unveil a revolutionary addition to its scenic travel offerings with the introduction of the Gran Tenku sightseeing train, scheduled to begin operations on April 24, 2026. This new service promises to redefine the travel experience for visitors to Mount Koya (Koyasan), a UNESCO World Heritage site, providing an immersive journey that combines luxury rail travel with deep cultural and spiritual exploration.
The Gran Tenku train will run along the Koya Line, connecting Osaka’s Namba Station to Gokurakubashi Station, the last stop before a cable car ride up to the sacred Mount Koya. Known for its Buddhist temples, tranquil atmosphere, and historical significance, Mount Koya is one of Japan’s most important spiritual destinations. The Gran Tenku offers a seamless way for both domestic and international travelers to access this renowned site, making the journey just as enriching as the destination itself.
A Journey into Japan’s Spiritual Heart
The concept of the Gran Tenku is more than just a train ride; it is an opportunity for travelers to experience the serenity of Mount Koya before even arriving. The train’s design focuses on creating a luxury, cultural experience, offering passengers panoramic views of the changing landscapes as they journey from bustling Osaka to the peaceful mountain region. The name “Gran Tenku” reflects the journey’s blend of grand comfort and heavenly views, with “Tenku” symbolizing the sky or heaven, linking the train’s route to the lofty, spiritual heights of Koyasan.
As travelers step aboard, they will be surrounded by interiors designed to complement the natural beauty outside. The Gran Tenku features spacious, well-appointed carriages with large windows for unobstructed views of the rural landscapes, lush forests, and historic sites along the way. Passengers can expect more than just comfort; they will experience an immersive glimpse into Japan’s spiritual heritage, thanks to the curated design and ambiance onboard. The train aims to attract both spiritual seekers and travel enthusiasts who wish to explore the traditional and modern facets of Japanese culture.
Mount Koya: A UNESCO World Heritage Destination
Mount Koya has long been an essential pilgrimage site for followers of Shingon Buddhism, with Koyasan being the headquarters of this religious tradition. Its ancient temples, peaceful atmosphere, and sacred cemeteries are steeped in deep spiritual significance. In addition to its spiritual allure, Koyasan offers a wealth of cultural experiences, including staying in shukubo (temple lodgings), where visitors can practice meditation and partake in traditional Japanese Buddhist meals.
With the Gran Tenku train, Nankai Electric Railway seeks to make the journey to Mount Koya even more accessible to visitors worldwide, enhancing the spiritual tourism sector. By offering this premium train service, the company hopes to draw attention to the spiritual tourism potential of the Kansai region, bringing more international tourists to discover Koyasan’s rich history and cultural heritage.
Luxury Travel Meets Spiritual Exploration
The Gran Tenku train stands out for its luxurious features designed for ultimate comfort. The train boasts four specially designed carriages that blend luxury with the theme of cultural travel. With seating designed for only 70 passengers, the train offers an exclusive atmosphere, ensuring that every traveler has a premium experience. Inside, guests will find spacious seats that allow them to relax and enjoy the passing scenery in style.
This level of service is not typical for Japan’s traditional rail system, which is known for its speed and efficiency, but less for luxury. The Gran Tenku offers something entirely different—a chance to slow down and appreciate the cultural richness of Japan’s landscapes. It will operate daily, providing a unique travel option for visitors seeking a more introspective and scenic journey.
The train’s amenities also include relaxation lounges and restaurant-style services, where passengers can enjoy local delicacies while taking in the views. For those interested in Japanese culture, the train will also feature interactive elements related to Shingon Buddhism and the significance of Mount Koya. This blend of luxury and spirituality aims to attract travelers from all over the world who want to explore Japan’s unique combination of modernity and tradition.
Regional Tourism Boost and Global Appeal
The launch of the Gran Tenku train is expected to have a significant impact on regional tourism. While Osaka and Kyoto remain major tourist destinations, the addition of this luxury rail experience to Mount Koya provides a unique option for travelers seeking a more authentic and culturally rich experience in the Kansai region. By enhancing access to one of Japan’s most sacred sites, the train will likely increase the number of visitors to Koyasan and surrounding towns, benefiting local businesses, hotels, and cultural sites.
In a broader context, the Gran Tenku also positions Japan as a premier destination for scenic rail travel, akin to the world-famous Golden Eagle in Russia or the Rocky Mountaineer in Canada. Japan’s attention to detail, comfort, and cultural engagement is pushing the envelope on luxury train travel in Asia, making it a more globally attractive destination for rail travel enthusiasts and spiritual seekers alike.
An Elevated Travel Experience
For travelers seeking both luxury and spiritual exploration, the Gran Tenku train to Mount Koya offers an entirely new way to experience Japan. Whether visiting to immerse themselves in the ancient world of Shingon Buddhism or simply looking to experience Japan’s stunning natural beauty, this train promises to redefine travel expectations.
As April 2026 approaches, excitement around this new addition to Japan’s tourism infrastructure is building. With its luxurious comfort, scenic views, and deep cultural connection, the Gran Tenku train is set to become a must‑see attraction for those looking to experience the spiritual and natural beauty of Japan in an entirely new way.
