Your answer: Brazil → Japan
Plug adapter
Adapter required
Japan uses Type A, B; your Brazil plug (Type C, N) doesn't fit. Pack a Type A/B adapter — or a universal one if you travel often.
Voltage converter
Not needed
Both countries are on the same low-voltage standard (127V in Brazil, 100V in Japan). Your devices work as-is.

What this means for your trip
Going from Brazil to Japan you'll need a plug adapter, but voltage is identical on both sides, so that's one less thing to worry about.
Japan uses Type A/B outlets; Brazil uses Type C/N. The shapes are incompatible, so every plug you bring needs a Type A/B adapter to reach the socket. The cheapest option is a simple shape-only adapter for that one country; if you travel often, a universal adapter (fits every country) pays for itself in a single trip.
Voltage is the same on both ends (127V vs 100V, 60Hz vs 50Hz), so every charger that works at home works in Japan without modification. No voltage converter, no hunting for "100-240V" on the brick.
Frequently asked
Do I need a travel adapter for Japan from Brazil?
Yes. Japan uses Type A/B outlets, which don't accept Brazil's Type C/N plugs. Pack a Type A/B adapter — or a universal one if you travel often.
What type of plug does Japan use?
Japan uses Type A and Type B outlets at 100V, 50Hz. Two flat parallel pins. Common in North America, Central America, and Japan.
What's the voltage in Japan?
Japan runs on 100V at 50Hz. That's on the low-voltage standard, lower than Brazil's 127V supply. Most modern phones, laptops, tablets, and camera chargers are dual-voltage (check for "100-240V" on the brick) and work on either. Single-voltage devices like hair dryers, curling irons, and travel kettles will not — bring a dual-voltage travel version or a voltage converter.
Are Brazil chargers dual-voltage?
Most — but not all. Check the charger brick for a line that reads something like "INPUT: 100-240V, 50/60Hz." If you see that, the charger works on either voltage standard and you only need a plug adapter. If it lists just "120V" (or just "230V"), it's single-voltage and can't be plugged straight into the other side without a voltage converter.
