In 1971, the Japan Toy Association (JTA) established Toy Safety (ST) Standard and Safety Toy (ST) Mark Program to improve toy safety in Japan. This standard and program has contributed greatly to toy safety since then.
The ST Mark is given to toys that comply with the Toy Safety Standard, which has been regulated by the Japan Toy Association since 1971. The ST Mark is only approved for use with toys whose mechanical and physical characteristics, flammability, and chemical properties have undergone strict safety inspection. Toys carrying this mark have been created with the utmost care and consideration and are officially approved as safe for use.
