A Japanese saw is a tool that helps people cut things like wood. It's different from a regular saw because instead of pushing back and forth, you only pull it back and the teeth cut while you do that. The handle is usually made of wood and fits nicely in your hand. There are different kinds of Japanese saws for different jobs, like cutting straight lines or making curvy shapes. They are great because they can make very precise cuts and are easy to use, even for beginners!
