Danchi is a residential building that began to be built in Japan during the 60s, when the economy was booming.

At that time, Japan's economy was developing rapidly, and a large number of laborers were pouring from the countryside to the cities.

In Japan, the original housing was single-door, single-family houses, which obviously could not meet the large housing demand, so a large number of land plots began to be built in urban areas.

Danchi is a Japanese Chinese word that refers to a planned and concentrated construction of apartment and residential buildings.

This type of residential building could provide many houses in one building, which greatly alleviated the housing problem in Japan at that time.

At that time, there were not as many high-rise buildings as there are now, and the planned construction of the regimental land looked magnificent, and the supporting household appliances were the symbol of modern life at that time - a three-piece set of televisions, washing machines, and refrigerators.

The regiment became an ideal housing for the people of the time.

With the acceleration of urbanization, urban land is becoming increasingly scarce, and large-scale residential building construction is gradually moving to suburban areas.

Construction has begun in the suburbs of Tokyo and Osaka, and this kind of large-scale residential community in the suburbs is called newtown, which is larger than the ordinary danchi and has more complete community facilities.

As a result, people who are struggling to find a place to live in the center of the city have new options.

They work in the city center during the day and rush back to their homes on the outskirts of the city at night, where the intense work and long commutes keep them at home for a short time, almost having to go to bed after dinner.

So Newtown was jokingly called Bedtown.

Half a century has passed in the blink of an eye, and the danchi and newtowns in Japan have become obsolete little by little, and the maintenance of danchi in many places has become a problem.

The original design of the house was aimed at a small family of three or four, and the young people who moved in were getting older, and their children were growing up and leaving home to form a new family.

The overall aging of the residents who stayed in the regimental area is very prominent.

In recent years, some of these residents have been widowed or divorced, and the number of elderly people living alone has gradually increased.

They live alone in cold apartments, some have no friends, no contact with neighbors, and children don't greet them.

In a long and lonely life, they gradually rely on frozen food, instant noodles, alcoholic beverages... The elderly in the apathetic city are always the most vulnerable people who are easily overlooked.
