Tama Hills eco tour
INAGI CITY, Japan -- Yoshitaka Yamaguchi, 374th Civil Engineer Squadron Environmental Flight, leads an eco tour of the Tama Hills Recreation Area May 13 for citizens of Inagi City. Yokota civil engineers lead five eco tours each year for citizens of Inagi City and Tama City, two communities which surround the recreation area. The site, a former Japanese Imperial Army munitions processing and storage plant, was so well concealed by the surrounding terrain that it remained undetected by Allied forces throughout World War II. Officials maintain the site's biodiversity and have also erected historical plaques throughout the 250-acre site containing bunkers, foundations and tunnels. (U.S. Air Force photo/Osakabe Yasuo)
