How to Deal with Cold Indoor Temperatures in Winter

Many Japanese apartments feel colder indoors than people expect. This guide explains what actually helps.

The problem in winter is not just the outdoor temperature. Many apartments in Japan are not insulated like homes in the US, so indoor temperatures can drop more than you expect.

Common solutions

• Use the air conditioner on heating mode
• Add thermal innerwear, slippers, and thicker curtains
• Use a humidifier if the air becomes too dry
• Warm bathrooms and changing areas carefully before bathing if possible
