Comment by Yuko Nagayama

Based on the expo’s theme of “connecting,” I conceived the theme of the architecture in particular as two types of connections: the cultural connection and the technological connection between Japan and the Middle East. In terms of the cultural connection, I took my starting point from the similarities we can see between Middle Eastern and Japanese geometrical patterns, and explored this across a facade that is a new kind of geometrical 3D lattice serving as the structure and environmental filter. For the technological connection, I wanted to incorporate the element of water based on the water technology long utilized in the Middle East region. It is my hope that future connections with the Middle East as well as between people can emerge from this pavilion.



Along with supporting the communications infrastructure for the NTT Group over a century, NTT FACILITIES harnesses the latest developments in ICT to provide an advanced fusion of experience and technology for energy and architecture cultivated across a wide range of professional fields. Specialists with varied expertise supply multifaceted services in energy conservation, cost reduction, and risk management in order to tackle the many problems society now faces in energy, architecture, and the environment.


By seeking out new approaches to energy through IoT measures for energy conservation or solar power and other means of energy creation and sustainable energy, and constructing the latest types of smart buildings, NTT FACILITIES contributes to addressing the environmental issues with which the Japan Pavilion is also concerned. Moreover, it aspires to combat global warming by realizing a decarbonized society.




Obayashi Corporation has handed down its DNA of honest craftsmanship and technology since its founding in 1892. We have relied on that DNA to complete buildings and infrastructure emblematic of their era. We completed Tokyo Central Station (currently Tokyo Station) in 1914. We later went on to rebuild the Main Tower of Osaka Castle and construct the Tokyo Bay Aqua-Line expressway. In recent years, we have engaged in construction of Roppongi Hills (a complex building in a large-scale redevelopment project) and TOKYO SKYTREE (the world’s highest free-standing tower).
Obayashi aims to be a leading sustainability company. Meanwhile, we are developing next-generation technologies including energy conservation tech and expanding our business into new domains. For example, we are leveraging the technology we have learned from the construction business to get into the renewable energy business.


Obayashi has played an active role in constructing facilities for many expositions since the 1903 National Industrial Exhibition in Osaka. We constructed halls and pavilions for Japan World Expo '70 in Osaka, Expo 2005 in Aichi, and Expo 2010 in Shanghai. For Expo 2020 in Dubai, our Group company Obayashi Middle East will construct the Japan Pavilion. In this project, the Obayashi Group will make full use of our abundant knowledge and expertise from years of experience. The new pavilion will give people a new place to meet the world in the Middle East.
