Do I need a voltage converter for my iPhone in Japan?

No. iPhones and most modern smartphones are dual voltage (100-240V) and work fine with Japan's 100V power. You just need the right plug adapter if you're not from North America.

Can I buy electronics cheaper in Japan?

Some items like portable chargers, headphones, and camera accessories can be good value in Japan, especially at duty-free shops. However, major electronics like laptops and phones are often more expensive than US prices.

What about bringing my hair dryer to Japan?

Hair dryers from 220-240V countries (Europe, Australia) will not work properly in Japan's 100V system without a voltage converter. North American hair dryers work but may run slightly slower. Consider buying one in Japan instead.

Are there restrictions on portable chargers on flights to Japan?

Portable chargers must be in carry-on luggage and under 100Wh capacity (about 27,000mAh). Larger ones require airline approval. Remove all batteries from checked devices.

How to Pack Electronics for Travel to Japan

Japan uses Type A and Type B outlets (same as North America) with 100V power, so US travelers need voltage converters for high-wattage devices. Bring a universal adapter for other plug types, pack batteries separately for flights, and consider buying a portable phone charger in Japan where they're excellent quality.

Check your device voltage requirements. Look at the power adapter labels on your devices. Most modern electronics (phones, laptops, cameras) are dual voltage (100-240V) and work fine in Japan. Hair dryers, curling irons, and other high-wattage devices often need a voltage converter since Japan uses 100V.
Pack the right adapters. If traveling from North America, you likely won't need adapters since Japan uses Type A and B outlets. European, Australian, and UK travelers need a universal adapter or specific Japan adapter (Type A/B). Pack at least two adapters for multiple devices.
Prepare portable chargers and batteries. Remove all batteries from devices and pack them in carry-on luggage. Portable chargers must go in carry-on and should be under 100Wh capacity. Japan has excellent portable chargers available at convenience stores if you need extras.
Organize cables and accessories. Pack all charging cables, camera memory cards, and device accessories in a dedicated electronics pouch. Bring backup cables for essential devices. Japan has excellent electronics stores (Yodobashi, BIC Camera) if you need replacements.
Consider regional electronics differences. If bringing gaming devices, check region compatibility. Some games and content may be region-locked. Pack headphones as many Japanese trains and public spaces expect quiet behavior.
