I remember reading a case of Japanese corporate culture before, and I am eager for a detailed case. Describe as follows

In Japan, one day, an international student drove a Toyota car to the supermarket for shopping. When he came out of the supermarket, he found an old man washing his car carefully. He thought the old man might be a beggar, but on closer inspection, he was well dressed and had an extraordinary temperament. When he approached Toyota, the old man bowed deeply and said, "Thank you for using Toyota. As a Toyota person, I have an obligation to clean your car. " A retired man has such strong feelings for his company's products. This is Toyota culture, a spiritual belief rooted in the hearts of Toyota people.
