Tokyo City Symphony

In celebration of the tenth anniversary of Roppongi Hills, a renowned landmark of Tokyo, its developer, Mori Building Co., Ltd. (Headquarters in Minato-ku, Tokyo, Japan, President and CEO: Shingo Tsuji) has launched a sensational digital campaign TOKYO CITY SYMPHONY on April 23, 2013 (JST) as one of the main features of the anniversary project carried out under the theme “LOVE TOKYO”.

The TOKYO CITY SYMPHONY digital campaign is an interactive website which allows users to experience playing with a 3D projection mapping on a 1:1000 miniature model of the city of Tokyo. The handcrafted model is an exact replica of the cityscape of Tokyo in every detail.


Three visual motifs are projected onto the city in sync with music: “FUTURE CITY,” conjuring futuristic images, “ROCK CITY” that playfully transforms Roppongi Hills into colorful musical instruments and monsters, and “EDO CITY,” or “Traditional Tokyo,” that portrays beautiful Japanese images.


Users can play a complex, yet exquisitely beautiful harmony on the city by pressing the different keys on the computer keyboard. Each key would then play a different beat along with various visual motifs, creating over one hundred different sound and visual combinations. Each user is assigned a symphony score of eight seconds and this can be shared on Facebook, twitter and Google+. The numerous symphony scores submitted by the users are put together online to create an infinite symphony.


The miniature model of Tokyo used for this project owned by Mori Building Co., Ltd., is known to be one of the largest in Japan at five square meters. Each building was actually photographed and carefully handcrafted. This elaborative city model was used at a presentation to the IOC (International Olympic Committee) delegation in 2009, on the bid to host the Olympic Games. At the TOKYO CITY SYMPHONY website, users can experience playing with 3D projection mapping on a massive piece of land at the heart of Tokyo, which would in real life, cover over 6,400 acres of the city.


Japan’s very best creators have teamed up for the TOKYO CITY SYMPHONY. Heading the team as creative director is Tsubasa Oyagi, the winner of numerous awards including three Gold Lions at the 2012 Cannes Lions for the OK Go x Pilobolus: All Is Not Lost-Video Dance Messenger, and the Grand Prix at the Japan Media Arts Festival. This project is the first creation of Oyagi at his newly founded creative boutique SIX. P.I.C.S., a production house known for various interactive movie creations designed the projection mapping, and TAKCOM, a renowned creator trusted by top artists for music video production was assigned as projection director. Also on board are industry-leading creators Kampei Baba as web director and Takayuki Watanabe as programmer, both who work for Bascule Inc., famous for creating interactive websites. The music was entrusted to Koshi Miura, a member of Kuchiroro, an artist unit belonging to Ryuichi Sakamoto’s record label, popular across all ages.

TOKYO CITY SYMPHONY is just one of the various attractions planned for the celebration. Mori Art Museum will be showing “ALL YOU NEED IS LOVE – From Chagall toKusama and Hatsune Miku,” exhibiting the works by various artists including Yayoi Kusama and Hatsune Miku. Other fun activities include “Les Girafes,” a festive spectacle of eight meter tall giraffe puppets and a live performance by the French group COMPAGNIE OFF.
