Experience the Fascinating World of 'Chi': An Event at Tokyo City View

A Revolutionary Experience: 'Chi' at Tokyo City View

From April 10 to June 8, 2026, the Tokyo City View, located on the 52nd floor of Roppongi Hills Mori Tower, will host an extraordinary event in collaboration with the acclaimed manga 'Chi: On the Movements of the Earth,' illustrated by Uo Toyo and published by Shogakukan. This immersive experience promises to change the way we perceive the world around us, as we delve into the narratives of unnamed individuals from the Middle Ages who risked their lives to prove the heliocentric model in a time when geocentrism reigned supreme.

At 250 meters above sea level, this observatory transforms everyday views into spaces of intellectual exploration. Visitors will find themselves engulfed in the profound beauty of the universe as they connect with the experiences of medieval astronomers—whose passionate pursuit of knowledge and truth serves as a reminder of humanity's quest for understanding the cosmos. The backdrop of Tokyo's skyline, starkly visible from the observatory's glass windows, becomes a unique tapestry of lights and stars, yielding a mesmerizing landscape that tells stories of chance encounters, passion, and inspiration.

The exhibition will showcase iconic scenes and memorable dialogues from 'Chi', creating a visual narrative that truly immerses its audience. It will also feature an interactive space displaying artifacts related to the world of medieval astronomy, making it a must-see experience.

Stargazing with 'MEGASTAR'

An exciting highlight of this event includes the 'Starry Sky Theatre', brought to life by Takayuki Ohira and his Ohira Lab. Utilizing the cutting-edge next-generation planetarium system known as 'MEGASTAR', visitors will be treated to the sight of millions of stars—those not visible to the naked eye—juxtaposed with the mesmerizing night views of Tokyo. This spectacular experience creates a timeless space that blends the magic of the medieval night sky that enchanted the characters of 'Chi' with the brilliance of today's scientific advancements.

Takayuki Ohira is a notable planetarium creator who succeeded in developing a lens-projecting planetarium during his university days. Born in 1970 in Kawasaki, Japan, he subsequently joined Sony, continuously innovating within the field. His brainchild, the 'MEGASTAR', capable of showcasing 1.5 million individual stars, earned a Guinness World Record. Known for his involvement in numerous exhibitions that merge science, art, and music, Takayuki has received several accolades and continues to inspire budding astronomers and enthusiasts alike.

Exclusive Merchandise and Special Events

In addition to the experience, guests can look forward to exclusive merchandise related to 'Chi' and themed items centered around astronomy, stars, space, and science—ideal souvenirs to bring home the excitement of this unique event. Furthermore, during the event's run, there will be several engaging activities such as talk shows and workshops that deepen the guests' understanding of the theme and provide ample opportunities for interaction.
