Japan connectivity FAQs
What power adapter do I need for Japan?
A Type A adapter. Japan runs on 100V — the lowest in the world — so phone and laptop chargers are fine but Australian hair dryers and styling tools often underperform or won't work.
Is an eSIM better than roaming in Japan?
Usually, yes. Australian roaming day passes run about $5 – $10 a day, while a 15-day Japan eSIM with 10GB is typically under $15 total. eSIMs are data-only, so keep your Australian SIM active if you need calls or SMS one-time codes.
