As someone who spends several months each year traveling through Asia, I’ve tried countless SIM options but the eWave has become my go-to. I started my most recent trip in Osaka, moved on to Kanazawa for a tea ceremony, then rode the Shinkansen up to Sapporo. From the moment I landed at Kansai International, activation took less than five minutes. Just scan and I was online. Speeds in Tokyo and Osaka consistently hovered around 100 Mbps. Even on the bullet train between Nagoya and Tokyo, I only saw a brief dip to 4G for about 5 minutes, otherwise I maintained solid LTE. Battery drain was also minimal. I’d estimate a 3–4 percent hit per hour of moderate usage (maps, email, social media), which is better than most eSIMs I tested. Customer support was impressively quick when I messaged them to confirm my extension, within 5 minutes I had my plan renewed remotely. If you need an affordable and reliable, fuss-free connection across multiple prefectures, this eSIM is hard to beat.

Purchased for a business trip to Hiroshima. Activated instantly and delivered consistent 40–50 Mbps. Ideal for messaging and email on the go.
Elena Martinez (verified owner) –
I choose the 1 GB/day plan because I only needed data to upload small design files and handle video calls occasionally. After scanning the QR code at Narita, I was connected before grabbing my bags. During co-working sessions in Tokyo, I typically consumed 300–400 MB uploading slides and checking client briefs. The remaining data was enough for messaging and quick web searches. Speeds in Shibuya and Shinjuku averaged 55 Mbps, so uploading a 50 MB file never took more than a minute. On a weekend side trip to Kamakura, I used about 700 MB for photos and map navigation, and even after hitting 1 GB, I still could send text updates at 256 kbps. Battery usage remained low, about 5 percent per hour of mixed use. For remote workers or digital nomads who don’t need endless streaming but do require dependable, budget-friendly connectivity, this daily plan is exactly what I needed: straightforward, transparent, and dependable all over Japan.
