In recent years, alternative ruin tourism has gained popularity, attracting anime fans, ruin enthusiasts, and wedding photographers alike. From remote deserted islands and abandoned amusement parks to mining site ruins, the strong postmodern vibe ensures every snapshot is stunning. Japanese travel agencies have curated 7 of the latest "ruin" Instagram spots, unveiling their mysterious allure, legendary backstories, and unique features.

●Deserted Island Category

1. Hashima Island (Gunkanjima) [Nagasaki Prefecture] Nagasaki City

Hashima Island began coal mining development in 1890 and became a key pillar of Japan’s modernization through its coal mining industry. Though small, the island once housed nearly 5,000 residents at its peak. After closing in 1974, it became a deserted island, yet many of its former facilities—such as hospitals, schools, shrines, and a cinema—remain intact. In 2015, Hashima was designated a UNESCO World Heritage Site, drawing renewed attention and prompting tour operators to offer trips to this hauntingly atmospheric island.

2. Tomogashima [Wakayama Prefecture] Wakayama City

Tomogashima (Friend Islands) is a deserted island floating in the Kii Channel off Wakayama. It retains wartime gun batteries used by the Japanese army, with red-brick structures now covered in vegetation, creating a dreamlike landscape reminiscent of a real-life "Laputa." Loved by both ruin enthusiasts and anime fans, it’s a highly talked-about destination. Most of the island is open for exploration, accessible via speedboat from Kada Port.

3. Sarushima Island [Kanagawa Prefecture] Yokosuka City

Sarushima is the only deserted island in Tokyo Bay. Once used as a naval fortress with gun batteries, it’s now part of Sarushima Park with walking trails for leisurely strolls. The island retains its tunnels, barracks, and ammunition depots, offering glimpses of its past and preserving historical memories.

It’s just a 10-minute boat ride from Yokosuka’s Mikasa Bridge or about an hour from Tokyo, making it a must-visit for fans of light ruin travel.

●Amusement Park Category

4. Kezo Numa Amusement Park [Miyagi Prefecture] Osaki City

In 1979, a Sendai real estate developer opened Kezo Numa Amusement Park to boost local tourism. Due to the economic downturn, visitor numbers declined, and it closed in 2001. The Ferris wheel and other rides were preserved, and park staff continue regular maintenance. While entry is restricted, guided tours are occasionally offered to the public.

● Mining Site Ruins Category

5. Kitazawahuyu Sennkoubaato [Niigata Prefecture] Sado City

Located at the Sado Gold Mine, the Kitazawahuyu Sennkoubaato (Kitazawa Flotation Plant Ruins) is known as the “No. 1 flotation plant in East Asia” due to being the world’s first successful large-scale application of the froth flotation method for gold and silver ore extraction, and for its remarkably high processing capacity. Though visitors cannot enter the site, they can view the remaining concrete framework from the outside and still be struck by its overwhelming visual presence. During the tourist season, a nighttime light show is held, adding a magical atmosphere.

6. Former Shime Kōgyōsho Vertical Shaft Headframe [Fukuoka Prefecture] Shime Town, Sakawa District

The “Former Shime Kōgyōsho Vertical Shaft Headframe” was built by the Japanese Navy during wartime to secure coal supplies. Constructed using modern reinforced concrete techniques, the shaft extends 430 meters underground and the towering structure stands 47.65 meters high, exuding an unmatched presence. Although access is restricted, the area around it has been turned into a park, allowing visitors to appreciate up close the impressive scale and mysterious aura of this massive tower.

7. Osarizawa Mine [Akita Prefecture] Kazuno City

The Osarizawa Mine, which has been in operation for approximately 1,300 years, is said to be Japan’s largest mine. Legend has it that even the gold leaf used on the Great Buddha at Tōdai-ji Temple came from here. After closing in 1978, it was preserved as an industrial heritage theme park. Guided tour participants can view the ruins of the flotation plant and smelter, and the inside of the mine shaft features recreations of miners at work during its operational days.

※ Notes: Japanese ruins are also places where etiquette is highly valued. Before visiting, be sure to do your research and follow proper behavior—do not damage property or cause disturbances. These sites are still privately owned, so please use official entry points. Unauthorized entry may be considered trespassing. Many structures are old and in disrepair, posing risks of collapse, so always prioritize your safety.
