Keitai Mizu has begun! Read about the project as it unfolds.

Spatial Dialogues and the Boat People Associationas part of SHIBUYA: UNDERGROUND STREAMS, are holding a mobile treasure hunt for art! Keitai Mizu artists are wondering: would you like to join in?

When: 15 minute game, 2nd June @ 5pm and 6pm, 3rd and 4th June @ 11am, 12pm, 1pm, 2pm, 3pm, 4pm.

Where: Jingu-dori Koen Park, Shibuya, Tokyo


We’ve placed various water-related creatures and objects made by Australian and Japanese artists around the site.

Participants will be given 15 minutes to take camera phone pictures of the sea creatures whose habitat is Tokyo. You must then distinguish between the real and imaginary, local and foreign objects and send ONLY the images of Tokyo-related sea creatures to the Keitai Mizu Twitter account (@keitaimizu) via camera phone apps like Instagram.

The winner will be the one who correctly guesses the most objects in 15 minutes.

We will also feature a version of the game using Tokyo joao chizu to discover the underground rivers.

Images will then be uploaded to the Spatial Dialogues website.

Shibuya: Underground Streams is like a subterranean octopus, spreading its multiple tentacles across Jingu-dori Koen Park (a park in Shibuya) and emanating from shipping containers. Jingu-dori Koen Park is a place and space for leisure and respite from the cacophony of Tokyo yet this project encourages visitors to navigate the park’s unique cartography while reminding us that Tokyo comprises little rivers and hidden tributaries concealed under trains and roads. These secret detours and submerged narratives allow the artists to inhabit an unexpected terrain. Working offsite to gallery or museum programs, Japanese and Australian artists occupy the outdoors with a series of interventions through video projections, soundscapes, sculpture and a mobile treasure-hunt. Engaging a range of publics especially the passerby, visitors are invited to discover these temporary, mostly un-monumental, public artworks.

Geographies of place and space as social theory are subtly enacted in Keitai Mizu through a constellation of sculptural sea creatures, imaginary and real, scattered across Jingu-dori Koen Park. These mysterious forms are mobilized via an ingenious game: an outdoor treasure hunt whereby people are invited to capture the creatures on their camera phones and share with online audiences in order to create narratives about water, space and climate change. By deploying humour and gaming, the park becomes a place of enchantment and discovery. A site for clandestine encounters, this collaborative project carefully introduces artworks in a public setting. In doing so, the artists allude to the urgency of climate change, waterways, migratory flows and urban renewal.
