If you’re traveling to Japan soon, one of the smartest things you can sort out before you go is your data plan—because the second you land, you’re going to need it. In this video I break down how to choose the right eSIM for Japan travel based on what you’ll actually use data for in Tokyo (and beyond): Google Maps for trains, translation apps, restaurant bookings, messaging your hotel, and just getting out of the airport without stress. I also talk through what your options look like, what they really cost, and how to match a plan to your trip length so you’re not overpaying. I walk through how Saily works step-by-step: download the app on iPhone or Android, pick a Japan plan (or a regional Asia plan), install the eSIM directly on your phone, and then it connects automatically to a local network once you arrive. I’ve been using Saily for about two years and it’s been consistently reliable across multiple trips, plus they’ve expanded coverage and added features over time. I also cover practical details like plan sizes (starting at under $4 for 1GB/7 days), 5G support when available, and the fact that it’s data-only—so you’ll want WhatsApp, Telegram, or FaceTime for calls and texting. What makes Saily stand out for me is the extra security and privacy layer: ad blocking, web protection, and a virtual location feature that works like a mini-VPN. Add in data-usage alerts around 80% and 24/7 in-app live chat, and it’s one of the simplest ways to get affordable, fast data in Japan that just works when you land.
