Humidifier (加湿器)
Japanese winters can become very dry indoors, especially when the heater is on. A humidifier is a common winter appliance.
What this is
A humidifier adds moisture back into the air. Common types include ultrasonic, evaporative, steam, and hybrid models.
Why people in Japan use it
Winter indoor humidity can drop very low in Japan, especially with air-conditioning heat. That can affect your throat, skin, and overall comfort.
What may feel different for people from the US
In Japan, summer often calls for dehumidifying while winter calls for humidifying. That seasonal switch is more noticeable than in many parts of the US.
