My love for Japan began the moment I arrived in Tokyo. The country amazed me with its harmony of ancient traditions, cutting-edge technology, breathtaking nature, and a culture unlike any other. Since then, Japan has become a part of my life, and I return there again and again. Today I help travelers discover the real Japan: I create personalized itineraries, give lectures, and prepare guests for their unforgettable journey. I would be delighted to open Japan for you too!
An electrical outlet in Japan
Before packing your bags for Japan, it’s important to understand the country’s unique electrical system. Unlike many other destinations, Japan uses a specific combination of voltage, plug types and frequency standards that every traveller should be familiar with. This guide from the Itinerary Expert will help you prepare properly and avoid unpleasant surprises during your trip.
Japan’s Electrical System: Key Characteristics
One of the most important things to know about electricity in Japan is the voltage. While travellers from Europe and Israel are used to 220 volts, and those from North America expect about 120 volts, Japan operates on 100 volts. This difference can be significant for certain devices and is something you should check in advance.
Another key characteristic is that Japan is divided into two frequency zones. In the eastern regions-including Tokyo, Yokohama and Hokkaido-the electrical frequency is 50 Hz. In the western regions-including Osaka, Kyoto and Nagoya-the frequency is 60 Hz. This split dates back to the early development of Japan’s power network, when companies in the east imported German generators, while those in the west purchased American ones.
Tip from the Itinerary Expert: Before you travel, check the small print on your chargers and devices to confirm their supported voltage and frequency. It can save you money, time and frustration once you arrive in Japan.

Japanese power outlets are very similar to those used in North America. They follow the Type A standard, featuring two flat parallel pins. However, unlike modern American outlets, most Japanese sockets do not include a grounding pin. In newer buildings, you may encounter Type B outlets, which add a third hole for grounding.
Unique Grounding Solutions
A notable feature of Japan’s electrical system is its approach to grounding. Instead of integrating a third grounding hole directly into the socket, many Japanese homes include a separate grounding point. This is typically a small metal tab or screw located near the outlet where a grounding wire can be attached. Larger appliances such as refrigerators and washing machines often come with a dedicated grounding cable that connects to this point.
Devices That Work Safely in Japan
Understanding which devices will operate correctly in Japan is essential. Most modern electronics-including laptops, smartphones and tablets-come with power adapters designed to support a wide voltage range (100-240V) and both frequency standards. This information is usually printed on the device or charger.
Heat-producing appliances require special attention, as they are most affected by voltage differences. This includes:
- Hair dryers
- Hair straighteners
- Irons
- Electric kettles
If these devices are not built for international use, they may work poorly or even become damaged when used with Japan’s 100-volt system. In such cases, purchasing a local device or using a suitable voltage transformer is the safest choice.
Tip from the Itinerary Expert: When in doubt, avoid bringing heat-producing appliances from home-they are the most common source of electrical issues for travellers.

If you arrive in Japan and realise you need a plug adapter or voltage converter, you’ll find them easily in most major cities. Akihabara in Tokyo and Nipponbashi in Osaka are the country’s best-known electronics districts, offering every type of adapter, converter or accessory a traveller might require. Large retail chains such as Yodobashi Camera and Bic Camera also operate throughout Japan and stock a wide selection of travel-friendly electrical equipment.
Additional Options
In addition to specialised electronics stores, travellers have several convenient alternatives:
Many hotels keep spare adapters for guests.
100-yen shops, including Daiso, sell basic adapters at very low prices.
Large train stations and airports often have travel-gear shops that offer various adapters and small electrical accessories.
Tip from the Itinerary Expert: If you forget to pack an adapter, check with your hotel first-many provide them free of charge.
Charging Devices During Your Trip
Japan makes it easy to keep your devices powered throughout your travels. On modern Shinkansen trains, power outlets are located next to the window seats, so it’s worth requesting these when booking your ticket. Many restaurant chains, especially family restaurants and fast-food cafés, offer charging sockets for customers. You will also find public charging stations in large shopping centres and major train stations; some are free, while others require a small payment.

Purchasing Appliances for Use Abroad
If you’re considering buying electrical appliances in Japan to use in your home country, there are several important points to keep in mind. Most devices sold in Japan are designed to operate exclusively on 100 volts, which means they may not function correctly in regions with higher voltage standards. However, major cities and international airports often feature shops that specialise in products for travellers, offering appliances adapted for global use.
How to Identify International-Compatible Devices
When shopping for an appliance, check for labels such as “For Travel Overseas” or review the technical specifications to confirm that the device supports a 100-240V voltage range. This ensures the appliance can be used safely once you return home. It’s also helpful to verify whether the product includes the necessary plug adapters or if they must be purchased separately.

Before travelling to Japan, it’s a good idea to:
Review the specifications of all devices you plan to bring.
Carry a universal power adapter that fits Japanese outlets.
Use a voltage converter for any device that cannot operate on 100 volts.
Tip from the Itinerary Expert: A universal adapter is often the most useful item you can pack-it works anywhere in Japan and eliminates the guesswork.

Japan places a strong emphasis on responsible energy use. During the summer months, when temperatures and electricity demand rise significantly, the country often encourages both residents and visitors to reduce unnecessary consumption and use electricity efficiently.
