The Diet enacted a revised Japan Agricultural Standards Law on Wednesday, increasing penalties on those who falsely label food products.

The amendment to the law was unanimously approved during a House of Councilors plenary session. The revised law is expected to take effect around the end of May.

The revision came amid mounting criticism about the existing law's effectiveness following a spate of food false labeling scams.

Under the revised law, those who put false information on food labels, including falsified information about ingredients, will face up to two years in prison or a fine of up to ¥2 million.
