Japan Outlets: Guide for Those Arriving from Brazil

If you've just arrived in Japan from Brazil, one of the first questions is usually about Japanese outlets. Will Brazilian appliances work? Do you need an adapter? And is the voltage different?

In this Manual do Japão guide, we simply explain how outlets work in Japan, the differences from Brazil, and how to easily solve this by using proper outlet adapters, avoiding damage to your devices.

How are outlets in Japan?

In Japan, the outlet standard is Type A, with two flat parallel pins, similar to that used in the United States. Unlike Brazil, most residential outlets don't have the round grounding pin.

Instead, many outlets have their own grounding compartment, usually with a small cover or screw. Some appliances and adapters come with a green wire with a yellow stripe, which should be connected or fastened with a screw at that point to ensure proper grounding.

This system is common in Japanese homes and is completely normal, especially for appliances requiring greater electrical safety.

Important: Brazilian 3-pin outlets (Type N) do not fit directly into Japanese outlets.

Voltage in Japan vs. Brazil

Another essential point for those arriving from Brazil:

🇧🇷 Brazil: 127V or 220V
🇯🇵 Japan: 100V

Most modern chargers (phones, laptops, cameras) are auto bivolt (100–240V), but appliances like hair dryers, straighteners, and coffee makers may not work correctly or burn out.

✔️ Always check the appliance: Input 100–240V.

Brazil to Japan Outlet Adapter

The simplest and safest solution is to use a Brazil → Japan (Type A) outlet adapter.

This adapter:

• Allows using Brazilian appliances in Japan

• Does not change voltage (not a transformer)

• Is small, cheap, and easy to find in Japan or on Amazon Japan

⚠️ Attention: adapter does not convert voltage. For appliances that don't accept 100V, a transformer is needed.

Which adapter to buy in Japan?

For those who just arrived, we recommend adapters that are:

• Compatible with Type A

• Compact (good for travel)

• Have safety certification in Japan

👉 At Manual do Japão, we indicate tested and well-rated adapters on Amazon Japan, ideal for newly arrived Brazilians.

Quick summary for those who just arrived

• Japan's outlets are different from Brazil's

• Brazilian outlets don't fit directly

• Voltage in Japan is 100V

• Adapters solve the fitting issue

• Some appliances need a transformer

Conclusion

Understanding how Japan's outlets work prevents headaches in the first days in the country. With a simple correct adapter and attention to voltage, you can safely use your Brazilian appliances.
