Practice monasteries provide places for monks to study and practice, similar to Buddhist colleges in China temples. In Japan, monks can be passed down, so it has become a place to receive education.
Ordinary temples are those that have existed for a long time. Many monks exploit them for various reasons to make money. For example, the Wenquan Temple in Hekou Lake at the foot of Mount Fuji, where I live, is actually the task of these monks to spread Buddhism. Drinking is ok, so is falling in love.
There are also temples such as Hata Temple and Kiyomizu Temple, which have become famous historical temples, mostly concentrated in Kyoto and Nara. It has become a must-see spot for tourists, and it is also a historic site of Y. Most of the people working in this temple are believers or foreign workers, just maintaining health and safety.
