You moved to Tokyo from the US. Your hair managed fine back home — then June arrived and everything changed. Here’s exactly what’s happening and what works.
Why Tokyo Is Different From Anywhere in the US
Even Florida and Houston humidity — often cited as the worst in the US — doesn’t match Tokyo’s sustained 80–90% atmospheric moisture during rainy season and summer. US humidity tends to be intermittent. Tokyo’s is relentless for months. Products formulated for US conditions routinely fail here. Why Tokyo humidity is different →
The Voltage Problem
The US runs on 110V; Japan runs on 100V. Your American hair dryer technically works in Japan without a converter — but it’s operating outside its designed voltage range and will underperform over time. For stays over 6 months, a Japan-compatible dryer makes a real difference. Dyson Supersonic is dual voltage (100–240V) — works equally in Japan and the US. Best hair dryers in Japan →
