Japanese monks, known as "homeowners", are mainly responsible for the religious life of believers near temples, especially relying on the income from funerals and cemeteries to maintain a stable life. Japanese monks can get married openly, usually the eldest son inherits his father's mantle, which is called "heir" in Japanese; Sons below the eldest son will enter the society to make a living, choose their jobs freely, and sometimes become monks at home with their eldest brother. If a monk has no son, and his son is unable or unwilling to become a monk due to illness or other reasons, he is often the son-in-law of his eldest daughter and inherits his father's monk mantle.
Monks in Japan are generally highly educated, and Buddhist universities in Japan are very large. Many students are sons of monks who will be "homeowners" in the future, and some women who plan to be nuns in the future. Of course, Buddhist universities also accept students who are not monks, and the son of a monk does not have to study at Buddhist universities. In addition to Buddhism, Buddhist universities offer many other subjects, which are not much different from secular universities. They are qualified to be teachers or instructors in schools, juvenile reformatories, prisons and other places. So most Japanese monks can engage in social work.
After the Meiji Restoration, Japanese monks generally married, which was the product of specific historical conditions. Due to the famous Martin Luther Reformation in modern Europe, Protestant clergy broke the Catholic convention and began to allow marriage. We can't treat Japanese monks differently just because they get married, or think that Japanese Buddhism has only two treasures, Buddhism and Taoism, and there is no monk treasure. In fact, Japanese "workshop owners" are really doing the work of promoting Buddhism. They are by no means white believers, and the Buddhist life of ordinary believers is conducted under their guidance.
