At the Urban GX Village, where Obayashi Corporation will exhibit, we will offer displays and interactive programs that inspire a sense of anticipation for the future. Through this initiative, we will share the Obayashi Group's goal of a sustainable future society.
OBAYASHI Thinking explores how we build—from on-site realities tackling social challenges and core technologies to the design concepts behind our architectural projects.

Here are some of Obayashi's achievements
We completed the construction of Imperial Hotel, Kyoto, a project that harmoniously balances preservation, restoration, and expansion while inheriting the architectural character of the Yasaka Kaikan, a Registered Tangible Cultural Property of Japan. As the fourth hotel in the 135-year history of Imperial Hotel, this new property stands as a contemporary landmark that seamlessly integrates cultural heritage with modern design, creating a refined space in harmony with the historic streetscape of Gion.
Kirin BioMaterials Company, Limited Clinical Trial Material Facility
Following the establishment of Kirin BioMaterials, we constructed a clinical trial material facility that also houses office functions. The front facade expresses the energy and dynamism of Kirin BioMaterials.
A dam planned as a fundamental flood control measure for the Aigawa River basin in northern Osaka Prefecture, following the heavy rains of July 1967 known as the Hokusetsu Heavy Rainfall, has been completed. Constructed approximately 6 to 7 km from central Ibaraki City, the dam helps protect downstream areas from increasingly frequent short-duration heavy rainfall. It significantly enhances flood control capacity and contributes to creating a safer living environment for local residents.
Webcor, a member of the Obayashi Group, constructed “Oso Tower,” a student housing facility with approximately 400 beds, within the Mesa Court residential community at the University of California, Irvine. The building features enhanced study spaces and lounges designed to foster interaction among students, supporting both living and learning. It is an environmentally conscious building that is expected to achieve LEED Platinum certification.
OAK LOGISTICS CENTER NAGOYA
OAK LOGISTICS CENTER NAGOYA is an urban logistics facility developed, designed, constructed, and operated through collaboration across the Obayashi Group. Electricity generated by solar power is used within the facility, while surplus power is supplied to facilities operated by Obayashi Road. The facility also employs Obayashi’s proprietary microbial nutrient “Chloroclean™” to remediate groundwater contaminated with VOCs (volatile organic compounds).
