There seem to be more coin laundromats than there were 10 years ago. I felt that way when I lived in Tochigi Prefecture.
When I was in my twenties, I lived in a two-room apartment (with a toilet, but no bath) right next to Futako-Shinchi Station on the Den-en-toshi Line, and used a coin laundry to do my laundry.
それなりに重宝していましたが、不経済であること、衛生的にもちょっと、待ち時間がもったいないけど、仕方ないやら、必要性に迫られるやらで使っていました。
時はなのに流れ、アパートは減少し、風呂付きの賃貸マンションが急増するなかで、コインランドリーも減ってしまったと認識していました。
しかし、店内改装(男女別、過ごしやすくする工夫)やら、洗濯機と乾燥機の機能向上(技術革新)やら、業界としての努力が重ねられるとともに、長時間労働や共稼ぎという働き方が増えたことにより、「洗濯時間の短縮、省力化」へのニーズが高まった、という要因がコインランドリー事業の収益性を高めているのだと推測されます。
さらに、人口が増え続けている都市圏では、居住環境の影響も大きいと考えられますね。核家族化、高齢化、1人暮らし人口の急増による洗濯物の減少、深夜に洗濯機は使いにくい、日当たりの悪い部屋が多いといったことも、コインランドリーの需要を支えているのでしょうね。
In my family, coin laundry was very useful.
However, it is uneconomical, sanitary-wise, and the waiting time is a waste, but in my household, it can't be helped, and I use it out of necessity.
As time passed, the number of apartments decreased, and the number of rental apartments with baths increased rapidly, and I realized that coin laundry facilities were also decreasing in number.
However, as the industry has made repeated efforts, such as renovating stores (separated by gender and making it easier to spend time) and improving the functionality of washing machines and dryers (technological innovation), the number of long working hours and dual-income working styles has increased. It is speculated that this has increased the need for ``shorter laundry time and labor savings,"which is a factor that is increasing the profitability of the coin laundry business."
Furthermore, in urban areas where the population continues to increase, the living environment is likely to have a large influence. Demand for laundromats is also supported by the decline in laundry due to the proliferation of nuclear families, the aging population, and the rapid increase in the number of people living alone, the difficulty of using washing machines late at night, and the fact that there are many rooms with poor sunlight.
