Can I Use My Steam Deck 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 Steam Deck 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. Valve documents an included 45W USB-C PD supply and requires the AC source to match the rating on that supply. Its cited public documents do not establish the AC input range, frequency or grounding for every replacement. Read the exact supply label and follow Valve instructions.

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.
