Although it is the Internet age, the way people communicate with each other has also changed a lot. But Japan's traditional home mailbox still plays a big role. It seems that many people still can't live without the traditional home mailbox.
These custom mailing boxes are still busy every day. First, Japanese people have the habit of reading newspapers, and every family now generally subscribs to at least one newspaper. And every day a large number of advertisements of various kinds, what second-hand houses, what cram school, what sale, are crammed into the mailbox. The mailbox is full almost every day. This is the general function of Japanese home mailboxes.
Another important function of the Japanese family mailbox is to receive official and personal letters from the government and relevant departments. These are still the main means of communication. Matters of local government in Japan are usually directly addressed to individuals, such as letters and notices concerning taxes, health care and welfare, which are written and delivered through the post. There are also quite a few personal letters in the mail.
Sometimes postcards are still used in large numbers, such as sending postcards for New Year greetings, which is still an important thing for Japanese people to do during the New Year. Before the year to take out a certain amount of time to make a variety of postcards sent. On the first day of each year, the post office delivers New Year postcards to every mailbox. This is the first event of the Japanese New Year's Day. You can see the importance of email.
But in my observation, because the elderly in Japan are used to traditional print media. So the larger audience for print ads is also these older people. It can also be seen that in today's Internet era, the penetration rate of the elderly in Japan who use smart phones and other smart terminals is not as high as that of the elderly in China. So things like media, advertising, and personal contact are still traditional, which is one of the reasons email is still doing its job.
