The Japanese railrways of the end of the year beginning of the year

A happy new year! This year thanking you in advance!

I introduce the Japanese railroad of the beginning of the year this time at the end of the year.

In Japan, all-night service of the railways are performe from the last day of the year to New year's day.It is for visitors who go to new year's visit shrines.The night train isn't included.
However, it is decided when crews and station staffs work by a Japanese law in the middle of the night so that salary changes an extra it. Therefore, there is the route that isn't run all night by railroad either of the big city.
All-night service seems to be perfome by the subway of U.S.A and European subways throughout the year, but it is difficult in Japan.Because, it performes the check such as tracks of the midnight.
However, there is the person to want to operate the railroad for 24 hours.
