“Is tap water in Japan safe to drink? Why is my hair feeling so stiff and frizzy ever since I moved here?”
If you have recently moved to Japan as an expat, student, or worker, you might have noticed two surprising things about Japanese tap water:
- It has a faint chemical or metallic smell (known locally as “Karuki / カルキ”).
- Taking a shower leaves your skin feeling dry and your hair unusually coarse or frizzy.
The truth is, Japanese tap water is among the safest in the world to drink straight from the faucet. However, to keep it bacteria-free, Japanese water suppliers use a high concentration of chlorine. While completely safe, residual chlorine destroys natural hair moisture and ruins the taste of your morning coffee.
Don’t worry! You don’t need to waste thousands of yen buying plastic water bottles every week. Here are 7 tested, high-rating Japanese water filters, shower heads, and hair care items that will instantly upgrade your life in Japan!
