The Consumer Affairs Agency (CAA) embarked on an investigation into all 1,271 products that it has approved for "tokuho" -- or "food with specified health uses" -- labeling by Sept. 28.
The move has come in response to revelations earlier this month that a mail-order company based in Osaka had the "tokuho" approval revoked for its products because they had falsely labeled ingredient amounts.
The CAA instructed the approximately 200 companies that carry "tokuho" products to submit the results of their most recent tests on their products showing detailed ingredients -- either from analyses conducted by a registered testing organization or from tests they conduct as part of their standardized quality management protocol -- within a month.
The agency expects to receive data from April 2014 onward. It is also demanding that companies that have made slight changes to their "tokuho" products, or have stopped selling any such products report the changes to the CAA.
The agency plans to carry out unannounced inspections in the future.
