Travel essentials for Japan

Adapters, plugs, tap water, tipping and health basics.

Power & adapters

Type A, B adapter required

You need a Type A adapter. Japan's 100V is the lowest mains voltage in the world — modern phone and laptop chargers handle it fine, but Australian hair dryers, curling wands and shavers will run slowly or not at all.

100V, 50Hz in eastern Japan, 60Hz in western Japan

Tap water

Safe to drink

Tap water is safe and good quality everywhere in Japan. Public water fountains are common; bring a refillable bottle.

Staying connected

Outstanding, including in subways, on the shinkansen and in rural areas.

Japan is one of the best-value eSIM destinations — 10GB for 15 days is typically under AUD $15, versus $5 – $10 per day for Australian roaming.

Japan travel essentials 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 tap water safe to drink in Japan?

Yes. Tap water is safe and high quality across Japan, so a refillable bottle will save you money.
