Can I Use My Electric Toothbrush in Japan?

Q: What plug type does Japan use?

Japan uses Type A/B sockets at 100V / 50/60Hz.

Based on what's typical for this device — confirm on the label to be sure.

Typical profile: Check your electric toothbrush's label before using it in Japan.

Why

Compatibility is unconfirmed. Read the exact INPUT voltage range and frequency on your device or power supply, and compare them with the destination. The whole local range must be covered; 110–220V does not include 100V or 230–240V. Confirm the actual plug, grounding and manufacturer restrictions. Do not plug in while these details are unknown. Toothbrush charging bases vary: Oral-B lists 100–240V, 220–240V and 110V/60Hz systems. Check the exact base label and manufacturer travel instructions. A plug adapter changes fit only; use a compatible manufacturer-approved base when the local supply is outside the rating.

Japan runs 100⁠V / 50/60⁠Hz. Japan uses 100V — the lowest standard mains voltage of any developed country. Plugs look identical to US Type A/B, but the lower voltage means even a US 120V device runs slightly weaker. The frequency is split: 50Hz in the east (Tokyo), 60Hz in the west (Osaka). This matters only for motor- and clock-based devices, not for 50/60Hz-labeled chargers.

FAQ

Can I use my electric toothbrush in Japan?

Typical profile: Check your electric toothbrush's label before using it in Japan. Japan runs 100⁠V / 50/60⁠Hz on Type A/B sockets.

Will a travel adapter let me use my electric toothbrush in Japan?

Typical profile: Not by itself. First check the label — if your electric toothbrush is single-voltage, a plug adapter will not protect it from 100V.

Do I need a voltage converter for a electric toothbrush in Japan?

Typical profile: First check the label. If it says only 120V or only 230V and that does not match Japan's 100V, do not buy or use a converter until wattage and local voltage are confirmed.

What plug type does Japan use?

Japan uses Type A/B sockets at 100⁠V / 50/60⁠Hz.
