The Japan Aging Control Research Institute, completed in 1985, represents a distinctive example of late 20th-century institutional architecture designed by Kazuo Iwamura and Urban Design. Located in Fukuroi, Shizuoka Prefecture, this multifunctional facility seamlessly integrates research and testing laboratories, indoor athletic facilities, and clinical services within a single architectural framework. The building's design reflects the growing emphasis on comprehensive gerontological research during Japan's demographic transition period. Its thoughtful program organization demonstrates how institutional buildings can accommodate diverse functions while maintaining architectural coherence and efficiency for both research advancement and public health services.
