For decades, "sex hotels" near train stations or at motorways have been part of the nightlife of Japanese cities, according to German media.
In the years immediately after the end of the second world war, these short-stay hotels were depressed, but business boomed after the economic miracle of the 1960s and then languished in the 1990s.
Now, to expand its clientele and cater to discerning customers, "sex hotels" have all the high-end amenities of a traditional hotel, which guests can rent for only a few hours.

On January 8, according to the voice of the German radio station site reports, because of very low birth rate, aging, income stagnated and most Japanese housing level increase, analysts believe that one day, the hotel will lose attraction, appeal all this means that Japan's "taste" hotel must provide new experiences, and look for a new generation of customers.

Japan now has 25,000 sex hotels.
The industry says 500 million people visit sex hotels every year, or 1.4 million a day, or 2 percent of Japan's population.
Today's sex hotels cater to all sorts of wishes, from Hello Kitty to boxing ring beds.
An interesting hotel in Osaka is famous for its merry-go-round rooms.
Some rooms have ceilings that can be opened, romantic couples can lie in bed and watch the stars, others have appliances or mirrors.
All of these hotels and lobbies have room pictures for people to choose from.
The room is equipped with a bathtub and shower, a large double bed, a television, a vending machine for snacks, drinks and sex toys, a karaoke machine and a computer game console.
In some hotels, guests can also order food in their rooms.

However, the report said that sex hotels did not have so many luxury facilities in the first place. In the 1920s, due to the small, multi-generational, and lack of private space in ordinary Japanese family homes, clock rooms were created for couples.
Most of the clock houses were closed during world war ii, but as Japan's economy boomed after the Korean war, they sprung up again.

In the late 1960s, these hour rooms became known as "love hotels", or "love hotels", as they became more sophisticated.
Some look like old castles, churches or oil tankers. Some rely on neon lights to attract customers.
As competition intensifies, operators are offering special facilities, such as rotating beds, waterbeds and jacuzzis.
Mr. Watanabe said that, like other services, hoteliers must keep updating their equipment if they want to attract repeat visitors.
As a result, the hotel was upgraded and started to be built in good places, such as the lake and the mountains.
These hotels have begun to challenge traditional hotels and entertainment venues, offering spas and fine dining.
