Why is the post red?
The first post boxes were established in Japan more than 100 years ago, in 1871. At that time, mailboxes were still made of wood and did not have the red color we see today.
In other words, the post was not red from the beginning.
It was not until 1908, 37 years after the first post was built, that post boxes turned red.
It was in 1908, 37 years after the first post was built, that the first red post made of iron was placed in the town. The reason for painting the posts red at that time seemed to be that red was the most conspicuous color. The decision was based on what color would stand out best when placed in the town.
The reason why the post boxes are red is because the color stands out.
