What Will Happen to Nakano Sunplaza? The Uncertain Future of a Tokyo Landmark



Nakano Sunplaza, a landmark building in Tokyo’s Nakano district, has stood as a symbol of the area since its opening in 1973. For over 50 years, it has served as a beloved multi-purpose facility, featuring a concert hall, hotel, restaurants, and a wedding venue. But now, its future is hanging in the balance.


■ Nakano: Tokyo’s Hub for Hobbyists

Just minutes from Shinjuku by train, Nakano is a highly accessible and popular neighborhood. It's best known for Nakano Broadway, a shopping complex packed with stores dedicated to manga, anime figures, vintage cameras, watches, and all manner of niche collectibles. The area is also known for its great food and is a favorite among foreign tourists and locals alike.




■ A Unique Shape and Cultural Heartbeat

When it opened, Nakano Sunplaza's distinctive triangular design made it stand out in a city that had few tall buildings at the time. It was envisioned as a local landmark—and it became exactly that. The upper-floor restaurants offered spectacular views, and the building's dramatic silhouette became iconic.

At its heart was the 2,222-seat concert hall, which hosted countless live performances across genres. Over the years, it became a cultural touchstone for fans of idol pop, anime songs, and voice actors. It even earned a reputation as something of a “sacred venue” for fans of these scenes.


■ A Complicated Road to Redevelopment

The push for redevelopment began due to several factors: aging infrastructure, seismic safety concerns, and changes in ownership. Here’s a brief timeline:

  • 2002: Ownership transferred from the Ministry of Health to a public-private third-sector entity involving Nakano Ward.

  • 2008: Nakano Ward acquired full ownership and began formal redevelopment planning.

  • 2012: A structural survey revealed that the building failed to meet modern earthquake safety standards.

  • Early 2020s: Plans were announced for a massive new complex—Nakano Sunplaza City (tentative name)—featuring a 62-story, 262-meter skyscraper.

  • 2024: Demolition was scheduled to begin, but rising construction costs (from ¥181 billion to an estimated ¥350 billion) forced the project to halt.

  • Late 2024–2025: New proposals, including twin tower designs and more residential space, were floated but rejected.

  • March 2025: Nakano Ward officially announced that it would not approve the revised plans, effectively resetting the entire redevelopment process.


■ A Farewell Marked by City Pop Nostalgia

On July 2, 2023, Nakano Sunplaza hosted its final concert: a performance by Tatsuro Yamashita, a legend of Japanese city pop. It was a fitting, poetic farewell that reflected the building’s deep cultural roots.


■ A Symbol of Urban Dilemmas

Many local residents opposed demolition, calling for preservation of the building's unique architecture and cultural legacy. Yet rising material costs, complex negotiations with developers, and the lack of a clear path forward have left the building in limbo. The originally planned completion by 2029 is now unlikely.

For now, the iconic building stands unused—caught between the past and an uncertain future.

What’s clear is that leaving it in this half-finished state benefits no one. Residents, fans, and city planners are all watching anxiously to see what comes next. Nakano Sunplaza has become more than a redevelopment project—it’s now a test case in how Tokyo handles the delicate balance of nostalgia, necessity, and future growth.

Tokyo’s Public Road Karts: A Revolutionary Tourist Attraction or an Urban “Obstacle”?

As a Tokyo resident, I have to admit that watching tourists dressed in colorful character costumes racing through the streets on low-profile karts is quite an entertaining sight. It brings a bit of whimsy and brightness to the otherwise concrete-dominated urban landscape—a welcome break from the everyday routine of businesspeople and commuters.  Seeing groups of Mario-like characters zipping past famous landmarks like Shibuya Crossing or Asakusa’s historic temples can be oddly charming, making you smile even on a hectic day. Yet behind the smiles, selfies, and social media buzz, there lie some growing urban challenges that Tokyo must reckon with. Real-life Mario Kart — but not exactly “Mario Kart” These public road kart tours appeared around the early 2010s. The concept is clever and simple: tourists zip through famous Tokyo spots such as Shibuya, Asakusa, and Shin-Kiba on mini karts, dressed up in playful costumes. This is the only activity that lets you experience the world of J...

Super Simple Japanese History: From Emperors to Anime!

Japan’s history is a wild ride—from ancient emperors and sword-wielding samurai to sushi trains and anime culture. If you’ve only got a few minutes, here’s your fast-track crash course through the ages.  Ancient Beginnings (c. 14,000 BCE – 538 CE) Japan’s earliest people, during the Jomon period (c. 14,000–300 BCE) , lived in harmony with nature. They fished, hunted, and made intricate pottery—some of the oldest in the world. In the Yayoi period (c. 300 BCE–250 CE) , things started to change. Rice farming, bronze tools, and new social structures came in from the Asian mainland, especially China and Korea. These changes led to more organized communities and eventually, the rise of ruling elites. The Kofun period (c. 250–538 CE) is named after the huge keyhole-shaped tombs built for powerful leaders. The idea of a divine emperor, said to descend from the sun goddess Amaterasu, began here—setting the stage for Japan’s imperial legacy. Early Empires and Court Cul...
