The stone quarry ruins at Nokogiriyama in Chiba Prefecture have recently garnered attention as a spectacular viewpoint that evokes the worldview of Studio Ghibli’s masterpiece “Castle in the Sky.” The vertically hewn massive rock walls and lush vegetation sprouting from the crevices are reminiscent of the fantastical world where Pazu and Sheeta embarked on their adventure. This article provides a comprehensive explanation of this mystical place known as the “Laputa Wall,” covering everything from access methods and historical background to photography spots and nearby attractions.
About Nokogiriyama Stone Quarry Ruins “Laputa Wall”
A Spectacular View Reminiscent of Castle in the Sky
Nokogiriyama is a mountain with an elevation of 329.4 meters spanning across Kyonan Town and Futtsu City in Awa District, Chiba Prefecture. Among the stone quarry ruins scattered on the north slope of this mountain, the place known especially as the “Laputa Wall” is characterized by a vertical rock wall reaching a height of approximately 96 meters.
The rock wall, which was vertically excavated to extract stone materials, has merged with nature over time, with vegetation growing through the crevices and moss covering its surface. This unique landscape, reminiscent of the ancient ruins depicted in director Hayao Miyazaki’s “Castle in the Sky,” eventually earned it the affectionate nickname “Laputa Wall.”
Industrial Heritage Born from Boshu Stone Quarrying
The stone quarry ruins of Nokogiriyama are not merely a tourist destination but also valuable industrial heritage that tells the history of Japan’s stone material industry. The “Boshu stone” excavated in this area is a type of tuff known for its ease of processing and excellent fire resistance, making it a high-quality stone material.
From the Edo period until the 1980s, excavation continued for approximately 300 years, with the stone being used in many historical structures including Edo Castle, Yasukuni Shrine, and Waseda University buildings. Quarrying was primarily performed by hand, with stoneworkers using traditional methods of splitting rock by driving in wedges called “arrows.”
The vertical rock walls visible today possess a beauty reminiscent of a massive sculpture, created as a result of digging deeper and deeper in search of quality stone materials, producing a tapestry of horizontal tunnels and excavation surfaces.

Attractions and Photography Spots at Laputa Wall
Main Photography Spots
Views from the Observation Deck
An observation deck is installed in front of Laputa Wall for safely enjoying the scenery. From here, one can look up at the 96-meter vertical rock wall directly and experience its overwhelming scale.
Countless traces of “arrow holes” left from the quarrying period remain on the rock wall surface, allowing visitors to observe the handwork of past stonemasons. On sunny mornings, the entire wall is illuminated, revealing the stone’s texture and color distinctly, making it ideal for photography.
Compositions from Horizontal Caves
Several horizontal caves remain at the quarry site, excavated in pursuit of quality stone materials. When looking out from inside these caves, one can capture compositions that feel like viewing from inside an ancient ruin as depicted in “Castle in the Sky.”
The contrast between the cave’s darkness and outdoor brightness, the stone’s texture, and the landscape woven by visible greenery through the gaps are popular for Instagram-worthy photography. However, some areas have unstable footing, so exercise caution for safety during photography.
Changes in Appearance Throughout the Day
Early Morning (6:00–8:00)
During misty hours, one can enjoy a more fantastical atmosphere. The massive rock wall emerging through the mist resembles the scene where Laputa Castle appears from within clouds. However, poor visibility of the ground requires sufficient caution.
Morning (9:00–12:00)
Sunlight illuminates the entire rock wall, and Boshu stone’s characteristic whitish color appears beautifully. This is the most suitable time for photography. Tourist crowds are relatively small, allowing leisurely enjoyment of the scenery.
Afternoon (13:00–16:00)
Shadows appear on the rock wall, emphasizing its three-dimensional quality. The strong contrast between light and shadow allows dramatic photography. Weekend afternoons see increased tourist numbers.
Dusk (16:00–18:00)
The rock wall bathed in sunset takes on warm orange hues. As sunset approaches, the wall’s silhouette appears mystically. However, darkness follows sunset, so attention must be paid to descent timing.
Other Attractions at Nokogiriyama
History and Attractions of Nihon-ji Temple
Nihon-ji, an ancient temple believed to have been established in 725 by imperial decree of Emperor Shomu, is located on Nokogiriyama. Known as the oldest imperial temple in the Kanto region, the grounds contain numerous attractions.
Nihon-ji Great Buddha (Yakushi Rurikō Nyorai)
A Buddha statue carved into the cliff face with a height of 31.05 meters, it is one of Japan’s largest. More than twice the size of the Great Buddha in Kamakura (approximately 13.35 meters tall), its magnitude is awe-inspiring. In 1783, Hidenori Ōno and his 27 disciples spent three years carving it.
Once deteriorated through weathering, it was restored over 6 years in 1969 to its current form. As Japan’s largest seated Buddha and said to be larger than the Great Buddha in Nara, its significance is immense.
Jigoku no Nozoki (Hell’s Lookout)
An iconic spectacular spot of Nokogiriyama, this is a rock jutting out from a 100-meter cliff where one can stand and view a vast panorama of Tokyo Bay below. Those with acrophobia may find it challenging, but the view becomes a lifelong memory.
On clear days, one can view Yokohama, Kawasaki, Tokyo’s urban skyline across Tokyo Bay, and even Mount Fuji.
Hyakushaku Kannon
A Kannon statue approximately 30 meters high carved into the quarry rock wall. Created between 1960 and 1966 to honor those who died and perished in World War II and traffic accident victims, this statue maintains harmony between natural and artificial elements, conveying a solemn atmosphere. It represents an interesting example of quarry site utilization distinct from Laputa Wall.
Sengohyakurakan (1,500 Arhats)
Over 1,500 arhat statues are placed on cliff surfaces and within caves at the quarry site. Created from the late Edo period through the Meiji era by disciples, each statue has a unique expression. It is said that as one gazes upon these arhats, one will surely find a face resembling oneself or an acquaintance.
Tokyo Bay’s Spectacular Panoramic View
From near Nokogiriyama’s summit, one can enjoy 360-degree panoramic views. Beyond Tokyo Bay, one can see mountains of the Boso Peninsula, the Izu Peninsula, and on clear days, even Mount Fuji.
The view from the observation platform is particularly exceptional, with ships passing through Uraga Channel visible below, the Miura Peninsula and Yokohama’s Landmark Tower on the opposite shore, and even Tokyo Skytree visible in the distance. At dusk, the beautiful scenery of the sunset over Tokyo Bay and the lights of the opposite shore unfold.

The Relationship Between Laputa Wall and Castle in the Sky
Official Connections
Importantly, the Nokogiriyama stone quarry ruins called “Laputa Wall” have not been officially acknowledged by Studio Ghibli or director Hayao Miyazaki as a model location for “Castle in the Sky.” Rather, because its landscape resembles the film’s worldview, visitors began calling it “just like Laputa,” and the nickname “Laputa Wall” eventually became established.
Studio Ghibli generally maintains a policy of not explicitly stating whether locations are settings or models for their works. This reflects the production team’s intention to allow viewers to freely expand their imagination.
Why It Resembles Laputa
Atmosphere of Ancient Civilization Ruins
The Laputa Castle depicted in “Castle in the Sky” is a massive sky-city left by an advanced ancient civilization. Stone structures covered in greenery that convey the passage of time share many similarities with Nokogiriyama’s quarry ruins.
Vertically hewn rock walls, regularly spaced arrow hole marks, light streaming through horizontal caves, and vegetation growing from rock crevices—these elements combine to create a mystical landscape where human creation and nature have merged.
Nature’s Return After Human Intervention
In the film, Laputa Castle is portrayed as a once-flourishing civilization that has gradually returned to nature after its decline. Nokogiriyama’s quarry site similarly shows nature reclaiming a place abandoned decades ago as quarrying ceased, perfectly aligning with this worldview.
Verticality and Openness
One impressive aspect of the film is the giant walls and structures of Laputa Castle. Nokogiriyama’s quarry ruins similarly evoke the grandeur of Laputa with their overwhelming scale provided by the 96-meter vertical rock wall.
As a Sacred Site for Ghibli Fans
Despite the absence of official connections, “Laputa Wall” is recognized among Ghibli fans as one of several “sacred sites.” Many who have actually visited report experiencing the sensation of entering the film’s world, sharing these experiences on social media.
However, when visiting, please keep the following in mind:
- Understand that this is not an officially designated Ghibli sacred site
- Show consideration for locals and other visitors
- Respect natural environments and historical sites
- Exercise appropriate conduct
History and Cultural Value of Boshu Stone
History of Boshu Stone Quarrying
Boshu stone quarrying began in earnest in the 17th century during the Edo period. The tuff found at Nokogiriyama was highly valued as a building material due to its ease of processing and excellent fire and water resistance.
Edo Period Prosperity
During the Edo period, vast quantities of Boshu stone were used in Edo Castle’s stone walls, samurai residences, and religious buildings. Stone shipped from Kanaya Port to Edo greatly contributed to the city’s construction. During this era, many stonemasons gathered around Nokogiriyama, and the stone industry flourished.
Development in Meiji, Taisho, and Showa Eras
From the Meiji era onward, as modern architectural demand increased, Boshu stone quarrying expanded. It was used in military facilities in Yokosuka, government buildings in Tokyo, university structures, and many other important buildings.
Quarrying techniques also evolved, with machinery supplementing hand labor. However, the traditional method using “arrows” remained the primary technique, with skilled stoneworkers’ techniques passed down through generations.
Late Showa Period Decline
From the 1950s onward, the demand for stone declined as concrete became widespread, and quarrying gradually shrank. Around 1985, most quarry sites closed, ending approximately 300 years of Boshu stone quarrying history.
Structures Built with Boshu Stone
Historical structures using Boshu stone remain in various locations:
- Yasukuni Shrine: Used in stone walls and stone steps
- Waseda University: Multiple buildings including Okuma Auditorium
- Yokosuka Naval Facilities: Docks, warehouses, etc.
- Edo Castle: Portions of stone walls
- Zojoji: Stone steps and stone walls
- Kamakura Temples and Shrines: Stone steps, stone walls, etc.
These structures demonstrate Boshu stone’s durability, maintaining their original appearance over 100 years later.
Value as Industrial Heritage
The Nokogiriyama quarry ruins are valuable industrial heritage conveying the history of Japan’s stone material industry. Arrow holes remaining in vertical walls, horizontal caves excavated for quarrying, and traces of transport routes all tell of quarrying techniques and labor practices from that era.
In recent years, the value as industrial heritage has been reassessed, with preservation and utilization initiatives emerging. Beyond its value as a tourist resource, it holds high educational value as a place to learn about local history and culture.
