These have been around for quite some time. I remember encountering them in Japan about 13 years ago. It was in a fancy store in Tokyo, next to the Palace. As soon as I entered, my 30 year old ears alerted me that they hadn’t died off at 25 as planned. The one clerk in the store couldn’t turn it off and apologized profusely. I decided to have fun, and in my broken Japanese, accused her of having a device to ward off gaijin. She denied it profusely as I walked out, laughing... on to the next store.
