Projects

Here are some of Obayashi's achievements

IMPERIAL HOTEL, KYOTO

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.

KINDAI UNIVERSITY, KINDAI UNIVERSITY HOSPITAL

This relocation project was undertaken as part of the 100th anniversary of Kindai University and the 50th anniversary of the establishment of its Faculty of Medicine. The relocated hospital serves not only as a provider of advanced medical care, but also as a high-level research institution and a core hospital in times of disaster. The campus also features five open plazas that provide welcoming gathering spaces for local residents.

AIGAWA DAM

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.
