One thing you should be aware of when living in Japan is mold.
Due to Japan’s hot and humid climate, mold can quickly grow on bathroom surfaces, shoes, and clothes if not properly managed.

Preventing Bathroom Mold
One of the most common places for mold to grow is the bathroom. Even Japanese people often struggle with keeping it under control. However, there are ways to prevent it.
If your bathroom has a drying function, make sure to use it every time after taking a shower or bath.
If there is no drying function, turn on the ventilation fan or open the window and door to improve airflow.
The most important rule is to do this every time to prevent mold buildup.
Dealing with Mold on Clothes, Bags, and Shoes
If mold has already appeared on your clothing, bags, or shoes, follow these steps:
Check the severity of the mold.
If the mold is mild, simply wiping it with alcohol should be enough to kill the spores.
If discoloration has occurred:
For colored fabrics: Use an oxygen-based bleach (such as "ワイドハイター") by applying it with a cotton swab or paper towel to remove the mold stains.
For white fabrics: Use a chlorine-based bleach (such as "キッチン・ハイター"). However, be careful, as chlorine bleach may cause discoloration on colored fabrics.
By taking these precautions, you can prevent and manage mold effectively in your home!
