Artificial Moons, 2020

The Makuhari New City, located in Chiba City, is sometimes mistakenly introduced as Makuhari City in overseas companies and news. Taking the words of the mayor at the time, "If everyone makes a mistake, it would be interesting to create a fictional city," to heart, the art project "Multilayered City 'Makuhari City'" was launched to explore what is necessary to create a new city. And this work, which was the first public art and exhibited as a city monument, was held as a commemorative exhibition with the support of Chiba City.
"Artificial Moons" is a light sculpture that takes as its theme the reality that emerges from a series of coincidences, based on the culture of "praying to and loving moonlight," which has existed throughout East Asia since ancient times and can be traced back to the Jomon period in Japan.
The nine moons, which are also the motif of the city crest of "Makuhari City", continue unpredictable movements in virtual space through N-body simulation, and a unique and enormous lighting system that is in sync with this movement illuminates a giant 150m building with a mysterious moonlight. This is a ritual that connects the fictional "Makuhari City" and the real Makuhari New City residents, and it is an attempt to breathe life into a brand new story while considering that "the source of life is the sun and the source of culture is the moon.”
In Japan, there are festivals such as the "Kebesu Festival" and one of the three major festival, the "Kanda Festival," but their origins are unknown. Also, the design of the "City Emblem," which is the symbol of the city, is sometimes made by puns or whim. For example, Fukuoka city has 9 "F" and Kurume city has 9 "R" in its emblem. Incidentally, the city emblem of Makuhari City uses nine moons, which is a pun using "ma(ru)," meaning circle in English, and "ku," meaning nine in English, from the word "Makuhari) In other words, whether it is a cultural anthropological ritual or a symbol for the cohesion of a modern community, all of the things that we see, participate in, and believe on a daily basis, called "Place of dependence," do not have a proper historical background that can be understood.
The Makuhari New City is a completely reclaimed land and a cultural desert without any historical or traditional foundations. For 1.5 months, this work was visible from over a kilometer away at night. What impact will this sudden event during the coronavirus pandemic, have on the memories of citizens and how will they inherit this fact? Can artificial moons, which were created in an artificial city, bring about connections of prayer and spirit there? We hope it will be a catalyst for transitioning from a cultural desert to a cultural forest.
For this work, a unique reflective lighting system using 16 moving lights, one of the world's largest in terms of light intensity as moving light, was constructed to produce natural light, and a 150-m-long building and virtual space were used as supports. It is also depicted in a science fiction short story created as part of the Multilayered City “Makuhari" project.
「Artificial Moons」は、東アジア一帯に古来から存在し日本では縄文時代まで遡ることができる「月の光に祈りを捧げ、また愛する」という文化を下敷きに、偶然の連続から生み出される実在性をテーマにした光の彫刻だ。
