An Immersive Exhibition 250 Meters Above the City
From April 10 to June 8, 2026, Tokyo City View（東京シティビュー）—the observation deck on the 52nd floor of Roppongi Hills Mori Tower—teams up with the cult-favorite manga Chi: On the Movements of the Earth（チ。 ―地球の運動について―） for a sky-high collaboration that feels less like a promo stunt and more like a philosophical flex.
If you’ve somehow missed it, Chi: On the Movements of the Earth（チ。 ―地球の運動について―）(by Uoto) is set in 15th-century Europe, when believing the Earth moved around the sun wasn’t just controversial—it was dangerous. The series follows those who risk everything to pursue heliocentrism in an era ruled by geocentric dogma. It’s sold over 5.5 million copies, won the 2022 Tezuka Osamu Cultural Prize’s Grand Prize (as its youngest-ever recipient), and was adapted into an anime in 2024.
The anime streams globally on Netflix under the title Orb: On the Movements of the Earth, reaching well beyond Japan. Turns out, existential dread and scientific rebellion travel well.
Now the series lands somewhere fittingly symbolic: 250 meters above sea level. The everyday Tokyo skyline becomes a stage for inquiry. Glass walls frame not just city lights, but the long arc of human obsession—with stars, with truth, with being right.
Inside, the exhibition leans into themes of astronomy, space and inherited knowledge. Expect iconic scenes and lines from the series woven into the space, plus installations that channel the worldview of medieval astronomers. Less “look at this cool panel,” more “why are we so afraid of being wrong?”
And then there’s the big draw: a pop-up “starry sky theater” powered by the next-generation planetarium system MEGASTAR（メガスター）, developed with Takayuki Ohira’s Ohira Tech. It projects millions of stars—far more than the naked eye can catch. Think: the kind of sky pre-electricity humans actually saw. Now place that over modern Tokyo’s glittering sprawl. Past and present, layered in light.
During the run, you’ll also find limited-edition collaboration goods, plus themed items riffing on astronomy, space and science. Talks and workshops are in the works; details are rolling out gradually.
It’s not every day you get to argue with the universe at 820 feet in the air. If you’ve ever looked up from a city street and wondered what we’re all doing here, this might be your stop.
