What is katatsu?

A kotatsu is a traditional Japanese heating table, consisting of a low wooden table frame covered by a futon or blanket, with a heat source underneath. It provides warmth during the colder months, allowing people to sit comfortably while enjoying meals or relaxing. The design encourages social interaction, as family and friends gather around it. Kotatsu are popular in Japanese homes and are often associated with cozy winter gatherings.
