Platforms in Japan are different from the platforms in Europe.
At first, the platform's level is as same as the train doors. Which means handicapped passengers on wheelchairs do not have big problems to get on and get off the train. Then, there are tactile pavings to assist passengers who are visually impaired. The yellow lines in the picture are the tactile pavings. Japanese stations now have more escalators and elevators than in 90s but tactile pavings were already introduced since 70s.
Also, there are more advertisements. These ads can be very widerange. It can be an ad of a concert of a foreign music band, products, services, hospitals, dentists and schools.
If you travel by train in Japan, you should check the platforms too!
