The UNEP International Environmental Technology Centre in Shiga, completed in 1995, stands as a significant example of late twentieth-century institutional architecture. Located in Kusatsu, Shiga Prefecture, this social education facility was designed collaboratively by Nikken Sekkei and the Shiga Prefectural Department of Civil Engineering and Architecture. The building exemplifies the thoughtful integration of environmental awareness into its architectural design, reflecting its purpose as a center dedicated to sustainable technology and environmental education. Its completion marked an important development in Japan's commitment to environmental initiatives during the post-industrial era.
