If you’re visiting Japan with your family, staying connected is not just a luxury—it’s a necessity. From navigating Tokyo’s complex trains to keeping kids entertained with YouTube, you need reliable internet.
I live in Japan, and I’ve tested various SIM options. Today, I’m reviewing Airalo eSIM.

🚀 Real Test: My Experience in Tokyo (2026)
Many people ask, “Is Airalo fast enough?”
I tested the Airalo “Moshi Moshi” plan here in Japan. It connects to the SoftBank 4G network — the same reliable network that covers Tokyo, Osaka, and Kyoto.
Here is the truth.
1. Speed & Stability
I consistently got 4G/LTE speeds. It wasn’t “lightning fast 5G,” but it was perfectly stable.
- Google Maps: Loaded instantly. No lag when searching for trains.
- Instagram/TikTok: Stories and videos loaded smoothly.
- YouTube Kids: My kids watched videos in the stroller without buffering. (This is the most important part!)
2. Personal Hotspot & Tethering: A Lifesaver for Parents
Yes, the Airalo Japan eSIM (Moshi Moshi) fully allows tethering and Personal Hotspot. You can easily share your data connection with your laptop for remote work, or connect your kids’ iPads to watch YouTube during long Shinkansen rides. There are no extra fees for using the hotspot feature—just turn on “Personal Hotspot” in your phone’s settings and you are good to go!
Did you know? Some ‘Unlimited’ SIM cards actually block tethering. But Airalo allows it! This means you can share data with your kids’ iPad during long trips like the Shinkansen. A total lifesaver for parents.”
🆚 Comparison: Airalo vs. Traditional SIM vs. Pocket WiFi
Why do travelers choose Airalo over renting a Pocket WiFi at the airport?
Why Airalo Wins for Families:
- vs. Pocket WiFi: Pocket WiFi is heavy and needs charging. You have enough to carry with a diaper bag and stroller. You don’t need another device!
- vs. Physical SIM: Swapping tiny SIM cards on a plane with a sleeping baby on your lap? Nightmare. eSIM is digital and instant.
🗣️ Reddit Q&A: Answering Your Fears
I checked Reddit (r/JapanTravel) to see what travelers are worried about. Here are the answers based on my local experience.
Q: “Is tethering (personal hotspot) allowed with the Airalo Japan eSIM?”
A: Yes, absolutely! Unlike many traditional “Unlimited data” SIM cards that block or restrict sharing, Airalo allows you to use your phone as a hotspot. You can freely share your data with your family’s iPads or laptops without any hidden fees.
Q: “Is 10GB enough for a 2-week trip?”
A: Usually, yes. If you use hotel WiFi for heavy downloads and only use data for Maps/Web/Social Media outside, 10GB is plenty. If you plan to watch Netflix on the train, get 20GB or download shows beforehand.
Q: “Does Airalo slow down (throttle)?”
A: Unlike “Unlimited” plans, Airalo gives you full speed until you use up your data. Many “Unlimited” SIMs slow down to 2G speeds after using 2GB/day. Airalo’s fixed data plans are actually safer and more reliable.
Q: “Is coverage good in rural areas?”
A: Yes. Airalo connects to SoftBank or KDDI, which are major Japanese carriers. I had a strong signal in Disney queues and city centers. (Note: Just like other SIMs, the signal can sometimes be unstable deep in subway tunnels.)
💡 How to Get Started (In 5 Minutes)
Setting it up is easier than you think. You can do this before you leave your home country.
