Stay Connected in Japan with eSIM
Get instant mobile data across Japan. Coverage in Tokyo, Osaka, Kyoto, and 200+ destinations. From $4.99 with no contracts.
Why Choose eSIM for Japan Travel?
Japan welcomes over 30 million tourists annually to experience Tokyo's neon-lit streets, Kyoto's ancient temples, Osaka's food culture, and Hokkaido's natural beauty. Staying connected in Japan is essential for navigating complex train systems, translating Japanese text, booking restaurants, and sharing cherry blossom photos. Many travelers traditionally rent pocket WiFi devices at airports for $8-15 per day, but this requires carrying and charging an extra device. Japan eSIM offers a better solution.
With My eSIM Global's Japan plans, you get instant mobile data access as soon as you land at Narita, Haneda, or Kansai airports. No need to wait in line for pocket WiFi rental, worry about device deposits, or remember to return equipment before your flight. Simply purchase your eSIM online before departure, scan the QR code, and you're ready to navigate Tokyo's subway, use Google Translate at restaurants, or video call home from a ryokan in Hakone. Your phone becomes your complete travel companion.

eSIM vs Pocket WiFi vs Roaming: Cost Comparison
Here's how Japan eSIM compares to pocket WiFi rental and international roaming for a typical 10-day trip to Japan:
| Option | Data Included | 10-Day Cost | Savings |
|---|---|---|---|
| Pocket WiFi Rental | Unlimited (throttled after 1GB/day) | $80-150 | - |
| International Roaming | Varies (often limited) | $100-150 | - |
| Japan eSIM (10GB/30 days) | 10GB high-speed data | $24.99 | Save $55-125 (70-85%) |
The savings are substantial. For a couple traveling to Japan for 10 days, choosing eSIM over pocket WiFi or roaming can save $110-250. That's enough for several sushi dinners, entry to multiple attractions, or a ryokan stay. Plus, you don't need to carry or charge an extra device, and there's no risk of forgetting to return the rental equipment.
