Shigeru Mizuki's Yokai Meets the Planetarium — An "Uncanny World"
What Is "Shigeru Mizuki's Yokai Summer Festival 88 Mysterious Constellations"?
Shigeru Mizuki spent his career depicting yokai from Japan and around the world, and his imaginative universe continues to captivate audiences today.
This event brings that world of Shigeru Mizuki's yokai together with the unique space of a planetarium, which projects a starlit sky.
Inside the dome, all 88 constellations floating in the night sky transform into "yokai constellations" — a little eerie, a little endearing. Visitors can also enjoy special footage offering an immersive experience unique to a planetarium, as if stepping directly into the yokai's world, along with festival game stalls given a yokai makeover.
From "a place to view the stars" to "an uncanny world" — enjoy this special experience, available only this summer, at Konica Minolta Planetaria Tokyo, where the line between reality and fantasy blurs.
