Can I Use My Laptop Charger 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: Your laptop charger can work in Japan if its actual input rating, frequency and plug match the local supply.

Conditional compatibility

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit.

Why

Use directly only if your actual input rating covers the local voltage and frequency and your plug fits with any required grounding. A typical category profile does not confirm your own unit. The cited Dell adapter accepts 100–240V, 50–60Hz, but one model does not verify every laptop supply. Read the actual INPUT label and preserve any required grounding. A voltage converter is unnecessary only when the full local voltage and frequency are covered and the manufacturer permits use.

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.

Conditional Dell guidance, not a no-earth claim for all laptop chargers.
Dell: 16S 65 W USB-C power adapter specifications: Power adapter, Table 1: 100-240 V AC, 50-60 Hz, 1.70 A maximum input; 65 W is rated DC output. This Dell 16S DS16265 example does not establish other supplies, category bounds or grounding.

Final check: look for "INPUT 100-240V" or a matching local voltage on the label before you plug in.
