Managing Humidity and Dry Air

Japan tends to swing between humid summers and dry winters. This guide explains how to respond to both.

Humidity is a year-round issue in Japan, but the direction changes by season.

In rainy season and summer

Focus on ventilation, dehumidifiers, and mold prevention.

In winter

Focus on humidifiers and keeping indoor air from becoming too dry.

A simple temperature-humidity meter can help you decide when you actually need to add or remove moisture.
