Tour of Traffic Light with Sounds in Japan

Hi, I'm Kyami, a Japanese.
I'm a traffic light geek.

In Japan, there are pedestrian crossings with sounds for visually impaired.
There are two types of sounds: melodic and onomatopoeic.

This channel, I am posting a video about the sound of traffic lights in Japan, which I have been researching for over 15 years.
Let's enjoy in the fun of Japanese traffic light with sounds!
