Have you ever seen a big lion made out of hard rock or stone that's usually placed outside buildings, like temples, shrines, or even homes? Yes? That's what we call a shishi or stone lion!
Shishis are considered to be protectors or guardians of buildings, and they are usually put in pairs - one with an open mouth and the other with a closed mouth. The one with an open mouth represents "ahh" which is the first letter of the Sanskrit alphabet, meaning birth or beginning. The one with a closed mouth represents "om" which is the last letter of the Sanskrit alphabet, meaning death. Together, they symbolize the cycle of life and death.
Some people believe that shishis can ward off bad luck or evil spirits, and that they can bring prosperity and good fortune to those who pass by them. That's why you might see people rubbing the shishis' noses or patting their bodies for good luck.
Overall, shishis might look fierce and scary, but they're actually friendly and helpful creatures that serve an important purpose in Japanese culture!
