日本 プリペイド旅行カード IIJmio eSIM

Connected straight away as soon as arrived. Internet speed is very good +150Mbps.
Had some issues from the beginning as couldn’t do wifi hotspot. Contacted technical support and the issued was fixed.
Used them previously in Thailand trip and South Korea trip. No one beats their price.
Highly recommend them👍🏼

This was my first time using an eSIM and I had a small panic when it wouldn't activate in Australia. I contacted support and they explained it only activates once you're inside Japan. They replied really quickly and everything worked exactly as they said after landing. Really appreciate the helpful customer service.

I was originally going to rent a pocket WiFi but decided to try this eSIM instead. Honestly I'm glad I did. No extra device to carry or recharge and I still had internet everywhere I needed it. Perfect if you're travelling solo or as a couple. Much simpler than dealing with another gadget.

Overall I was really happy with this eSIM and would happily buy it again. Installation was simple and coverage stayed reliable across Tokyo, Kyoto and Nara. The only reason I'm giving four stars is because speeds dipped a little during one evening around Shibuya Crossing when it was absolutely packed, but it was still perfectly usable for maps and messaging.

I received the QR code very quickly after ordering and setup only took a few minutes. Once I arrived in Japan the eSIM connected automatically without needing to change anything. Used it for Google Translate, restaurant bookings and uploading heaps of photos every day. The connection stayed fast even around busy stations.

Used this every day for Suica top-ups, Google Maps, translation apps and finding little cafés around Kyoto. The connection stayed reliable throughout the trip and battery usage seemed pretty reasonable too. It was one less thing to worry about while travelling.

Visited during cherry blossom season when everywhere was incredibly busy. Even with the crowds I could still upload photos, check transport times and book attractions without much delay. Used the connection every day from early morning until late at night and it never let me down.

Travelled on the Shinkansen between Tokyo, Nagoya and Hiroshima and the data stayed surprisingly reliable for most of the journey. Maps, messaging and music streaming all worked really well. Having internet available while changing trains made travelling around Japan much less stressful.

If you're planning to spend most of your time sightseeing instead of sitting in hotels, this eSIM is definitely worth it. We used it for booking tickets, checking train schedules, finding restaurants and even video calling family back home. Installation was easy and the speeds were consistently good across Tokyo and Osaka.

I installed the eSIM before leaving Australia and as soon as I landed at Narita Airport it connected within about a minute. Spent two weeks travelling through Tokyo, Kyoto and Osaka using Google Maps almost constantly. Directions updated quickly even while changing trains and I never felt the need to look for public WiFi. Really easy product to use.

Google Maps worked instantly and directions loaded fast. Very helpful in busy areas.

Setup took only a few minutes and instructions were easy to follow. No issues at all.

Speed was really good even in crowded areas. Maps and translations worked instantly.

Instructions were easy to follow and setup didn’t take long. Worked straight away.

Tried activating too early and thought it didn’t work. Once landed in Japan it connected fine.

Used in Tokyo, Kyoto and Hiroshima. Coverage stayed reliable everywhere I went.

Work fine overall but instructions could be a bit more clear for beginners. After setup, no issue.

No need to find airport SIM or WiFi. Just turn on eSIM and go. Very convenient after long flight.

Used daily for maps, booking tickets and messaging. Connection stable whole trip. Battery drain also not too bad.

Email instructions were clear and setup took just few minutes. Didn’t need to contact support at all. Everything just worked.

Speed was really good in crowded places like Shibuya and Osaka station. No lag when using translation apps or uploading photos.

Used it everywhere from Tokyo to Osaka on bullet train. Signal stayed strong most of the time. Even while moving fast, Google Maps still worked fine which was very helpful.

First time in Japan and first time using eSIM, was a bit unsure but actually very simple. Just scan QR, follow steps, done. If it doesn’t connect straight away, just wait until you arrive in Japan like they say.

Got the QR email within minutes after purchase, which was really quick. Installed before flight and it activated straight away once I landed in Tokyo. Data speed was very fast, even in busy Shibuya area. Used maps and train apps all day no issues.

I’m a bit of a tech dinosaur and accidentally deleted my activation email while waiting for my flight. I messaged Global Starlink on email and they re-sent the QR code through in under ten minutes. Once I landed in Tokyo, the eSIM worked flawlessly. That kind of customer service is rare these days!

Scanned the QR code at Sydney airport and it activated the second we touched down. Used it for Google Maps and Translate constantly with zero lag

Had a bit of a blue trying to activate it at Narita, but the support team on email sorted me out in minutes

Don't bother with the overpriced pocket WiFi rentals at the airport. This eSIM is cheaper and way more convenient. It connected to the local network immediately and the speeds were fast enough

Setup was a breeze on my Pixel—just scanned the code and I was sorted. Only giving 4 stars because I had to manually toggle 'Data Roaming' on to get it working, which I didn't realise at first.

Used this for a solo trip through Hakone and the Japanese Alps. I was worried about losing signal in the mountains, but it stayed strong the whole time

Needed reliable data for Zoom calls while travelling through Kyoto. The 5G speeds were top-notch.

Signal was 5/5 even on the fast trains. I accidentally deleted my activation email, but customer service sent a fresh one within the hour.
