Your Nintendo Switch charger's voltage range matches Japan's 100V and the plug fits, so you can use it directly — no adapter or converter needed. As a final check, confirm the voltage range printed on the device label.

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.
