Care Tips for your Kotatsu Table

Care Tips for your Kotatsu Table

A kotatsu is more than just a piece of furniture; it's a beloved part of many homes, especially during the cold winter months. This traditional Japanese heating system, which combines a table, blanket, and heat source, provides a cozy spot for family gatherings, relaxation, and even the occasional nap.

Like any cherished household item, a kotatsu requires a certain level of care and maintenance to ensure it continues to provide comfort and warmth for many years. This article provides a comprehensive guide on how to care for your kotatsu, from cleaning to storage and everything in between.

Understanding Your Kotatsu

Before diving into the maintenance aspect, it's important to understand the components of a kotatsu. The typical kotatsu consists of four main parts: a frame, a heater, a top, and a futon (the blanket).

Cleaning Your Kotatsu

Proper cleaning of your kotatsu is key to its longevity. Each part of the kotatsu requires a different cleaning approach.

Cleaning the Frame and Top

The frame and top of the kotatsu, usually made of wood, should be cleaned with a soft, dry cloth to remove dust and dirt. If necessary, a slightly damp cloth can be used for a more thorough cleaning. Avoid using harsh cleaning agents as they can damage the wood.

Cleaning the Heater

Safety first - before cleaning the heater, ensure it's switched off and unplugged. A vacuum cleaner can be used to remove dust from the vents, while a dry cloth can be used to wipe down the heater's exterior. Check the manufacturer's instructions for specific cleaning guidance.

Cleaning the Futon

The futon can accumulate dust and dirt over time, as well as potentially food or drink spills. Most futons come with a removable cover that can be machine washed. Check the cleaning instructions on the label. If it doesn't have a removable cover, a gentle vacuuming can help remove dust and a damp cloth can be used to clean spots.

Storing Your Kotatsu

The kotatsu typically isn't used all year round. When the weather warms up, it's time to store it away. Proper storage is crucial to prevent damage.

Storing the Frame and Top

Before storing, clean the frame and top as described above. Store these parts in a dry, cool place. You can cover them with a cloth to prevent dust accumulation.

Storing the Heater

Make sure the heater is clean and fully cooled down before storing. Wrap the cord carefully to prevent damage. Store the heater in a dry place where it's not likely to get damaged.

Storing the Futon

Clean the futon before storage. If it's machine washable, a final wash before storage is ideal. Once clean and dry, store the futon in a cool, dry place. Consider using a storage bag to protect it from dust and pests.

Regular Checks and Maintenance

Regularly check the condition of all kotatsu parts, especially the heater, for any wear and tear or potential issues. This can prevent small problems from turning into big ones. Ensure the heater works properly, and the cord and plug are in good condition. Check the frame and top for any damages.


Proper care and maintenance of your kotatsu can extend its lifespan and ensure it remains a safe and cozy part of your home. Remember, each part of your kotatsu needs specific care, from cleaning the wooden parts to washing the futon and safely storing the heater. With regular checks and proper storage, your kotatsu will be ready to provide warmth and comfort every winter!
