Can I Use My E-Reader (Kindle / Kobo) in Japan?
Your e-reader (Kindle / Kobo) can work in Japan if its actual input rating, frequency and plug match the local supply.
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.

Based on what's typical for this device — confirm on the label to be sure.
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. E-readers charge over USB from a dual-voltage adapter (100–240V). A plug adapter is all you need anywhere in the world.
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.
