Paintings on display in a Saitama gallery are renewing memories of a mineral poisoning case in the Meiji Era and the politician who tackled Japan's first known major environmental disaster.

The paintings by Iri and Toshi Maruki, the husband and wife team known for their works depicting the horrors of the U.S. atomic bombings of Hiroshima and Nagasaki, are being displayed at the Maruki Gallery for the Hiroshima Panels, located in Higashimatsuyama.

The exhibition is being held to mark the Sept. 4 centennial of the death of Diet member Shozo Tanaka at the age of 71.
