Just last month, many going for their morning stroll in Tokyo's Yoyogi Park looked up in the sky only to be shocked by the surreal sight of a giant floating head. The captivating but unnerving spectacle had many recalling terrifying scenes from horror manga legend Junji Ito's The Hanging Balloons, and with good reason!

While the mysterious floating head looming over Tokyo was certainly caused quite a morning of wonder and perhaps even terror for quite a few, it was revealed to be the latest creative endeavor by contemporary art collective [mé] as part of the Tokyo Tokyo Festival, a festival celebrating the art and culture of Tokyo.

The project, masayume, was something the group had begun working on months prior in collaboration with The Tokyo Metropolitan Government and Arts Council Tokyo (Tokyo Metropolitan Foundation for History and Culture), when they took online submissions from people around the globe willing to have their face float over the Tokyo Skyline in a massive weather balloon.

Well, just when we thought the sky was free of floating disembodied heads, masayume returned for a one day surprise (on of course, Friday the 13th) last week to float over Eastern Tokyo.

As for a refresher on exactly why the team chose for the giant head to float over Tokyo, masayume is a work of art that [mé] hoped to make a communal experience that didn't require for a crowd to gather in any one given place to see, instead being able to see head floating six or seven-story building and shared over social media, streaming, and genuine surprise.

In a press release, the group describes both the origin of the project and its intent--to cause reflection on the idea of "individual" and "public" when seen at a distance.

When viewed from a train, many may have imagined that the head might actually be attached to an unseen gigantic body.

Those who wish to follow the project can follow at the official website, as well as on Twitter. Perhaps you'll be able to spy on its next appearance, or even one day have your head floating above Tokyo!
