I grew up listening to Anzen Chitai/ Kooji Tamaki, and many other Japanese artists in the 80's and 90's. If you listen to him singing this same song when it was released, he sings now on the same tone. Many singers change the tone once they age as they can not reach the high notes anymore. A few years ago there was a survey among Japanese producers, composers... and they elected Tamaki sam as the best Japanese singer. His voice really touches deep in our hearts. BTW, there is a version of this song with an orchestra that he sings the end of the song without the microphone. It is amazing!!!
