Have you ever seen a stone with a rope hanging from it in a Japanese garden or in the precincts of a shrine or temple? This is called a "tome-ishi (stop stone)," and it is used to indicate that you cannot enter from this point on. The most common type of stone is a round stone with a black palm rope hung crosswise over it, and is sometimes called "sekimori-ishi" as well.

It is sometimes used as a stepping stone in the open space leading to a tea garden or a tea room, so that it does not interfere with a tea ceremony when one is being held there. It also serves to guide visitors to the right path by placing it on a path that divides into several parts.

The simple shapes of the stones blend in with the landscape, but they also play a variety of roles, such as representing boundaries and serving as signposts, and it can be said that tome-ishi is a culture filled with the deep consideration and wisdom of our ancestors.
