The toilets of new facilities such as department stores and theme parks are almost 100% Western style. However, if you look closely at the toilets on the Expressway, there is always a Japanese-style booth in some areas. The ratio is about 1: 9 for Japanese and Western style. This ratio has not changed since Nihondaira PA, the first modernized Expressway toilet in Japan. The reason is that the Expressway is a place that is used by all types of customers, young and old. As long as there are people who want a Japanese style, we want to respond to the voices of customers. Appearance of such feelings is 1: 9. It is a golden rate that treats all customers equally. Please continue to use both Japanese and Japanese schools with confidence.
