The market price of Japkasai is about 60 minutes = 20000 yen, 120 minutes = 30,000 yen, 180 minutes = 40,000 yen. Apart from the super-discount body care massage, the main price range of massage in Japan is about 60 minutes = 6000 yen, 120 minutes = 12000 yen, 180 minutes = 18000 yen, so the price more than double is the market of Japkasai. You can see that it is the price. For example, let's say you started a private business. Suppose you run 20 days a month. If one person is treated for 180 minutes a day, the monthly sales will be 360,000 yen. Of course, if you do it in earnest, it will be a business that makes a lot of money. Of course, it can also be recommended as a side business. If you perform the treatment for 180 minutes by yourself for 10 days a month, the monthly sales will be 180,000 yen. In any case, once you have acquired the skills, you can make a profit without incurring monthly purchasing costs. The massage business is a job that earns the trust of customers and increases the number of repeaters. It is a business model that will surely continue to increase profits as long as it can attract customers.
