Tokyo kuromu sabaku (1978)
In 1976, a year before the issue was still being discussed in the media, Yamamura and his crew visited Horie-cho, Edogawa-ku, the “town of hexavalent chromium,” and, based on Tsuchimoto's extensive data, traced the chromium that was dumped in various places in the Tokyo metropolitan area since the Taisho Era.
