畳（たたみ、taたmi）
- tatami mat

The Japanese word 畳, read たたみ (tatami), refers to a traditional type of flooring used in Japanese homes and other buildings. It's a modular flooring unit, typically rectangular in shape. The core is made of compressed straw, and the surface is woven with soft rush grass (igusa). 畳s provide a comfortable and resilient surface to walk on and offer a distinctive smell and texture. They also have insulating properties, helping to regulate the temperature of a room. The word 畳 can also be used as a counter word for counting the number of mats.
