Using Your eSIM Across Tokyo, Kyoto, Osaka, and Beyond

Breeze keeps you connected across Japan's busiest cities and most rewarding detours. Here's what that looks like on the ground:

Tokyo

Tokyo's transport system is incredibly efficient but can be overwhelming for first-time visitors. BreezeSim data keeps your Suica card topped up, lets you book Shinkansen tickets, and powers essential apps like Navitime and Google Maps, which provide real-time Tokyo Metro and JR East train information. Whether you're navigating Shibuya Crossing or finding your platform in Shinjuku Station, staying connected saves time.

Kyoto

Kyoto's famous temples, shrines, and historic districts are best explored with a reliable data connection. Use your phone to reserve timed-entry tickets where required, navigate the city's bus network, plan an early morning visit to Fushimi Inari, and discover hidden machiya teahouses tucked away in Gion's traditional streets.

Osaka

From sampling street food in Dotonbori to spending a day at Universal Studios Japan, BreezeSIM data can help you make the most of Osaka. You can check Tabelog restaurant reviews, book last-minute Universal Studios Express Passes, navigate the city's subway system, and avoid missing out on popular attractions.

Hiroshima

A connected phone enhances visits to Hiroshima's Peace Memorial Park with streaming audio guides and historical resources. BreezeSIM data also makes it easy to book the JR Ferry to Miyajima, check departure times, and navigate to the famous floating torii gate at Itsukushima Shrine.

FAQs

日本 eSIM FAQs

eSIM stands for "embedded SIM", because everything you need is digitally built into your smartphone or tablet. Think of it as the evolution of the SIM card, it's just like your old SIM, but better! Now there are no tiny holes or bits of plastic to deal with, so you never have to think about swapping out SIM cards again. Wave goodbye to the old and say hello to the future of mobile connectivity!

Ensure your phone is both network-unlocked and eSIM-compatible before making a purchase. All iPhones made since 2018, as well as most new Android models, are compatible. You can check your device's compatibility here. To find out if your phone is network unlocked, follow our guide here.

You can't make regular network calls or send SMS with your eSIM, but you can keep your existing SIM active if you still want access to these services. Just make sure you confirm any charges with your network provider before you travel. And remember, while Breeze eSIM plans are designed just for data, you can still use messaging and voice apps like WhatsApp, Messenger, iMessage, and more. These apps all work great with the data connection your breeze eSIM provides.

Your eSIM is delivered instantly to your email after purchase, no waiting, no shipping. Setting up your eSIM is easy, and we'll send a step-by-step guide after purchase. Or, you can head to our eSIM installation guide here.

First, you need to make sure you've got a reliable internet connection, so make sure you're connected to Wi-Fi. Go to Settings > Mobile Data > Add Data Plan. This can vary by model, so if you can't see this option, find your steps here.

  • Turn on mobile data and data roaming.
  • Scan the QR code. Open the camera and scan the code in the email you received after buying your eSIM. The easiest way to do this is to print your email or save the code to your computer screen.
  • Once you've scanned the code, you can download your eSIM straight to your mobile device.
  • Choose a name for your data plan.
  • Click the "data only" option. As breeze eSIMs are for data, you can keep your regular SIM if you want to make network calls or send SMS texts.
  • Make sure you turn off data roaming on your main SIM to avoid being charged for voice and text

We'll send you regular updates, and you can check the data used on your eSIM in the My Account area of your Breeze login.

Yes. Breeze connects to KDDI, providing coverage across all major cities, suburbs, and well-travelled highways in Japan.

Japan eSIM connects to KDDI (au), one of Japan's three national 5G operators alongside NTT Docomo and SoftBank. Your device automatically connects to the strongest available signal.

Your validity begins when your eSIM first connects to a network in Japan, not when you purchase or install it. Install before you fly and activate when you land.

If you need more data while travelling in Japan, log in to your Breeze account, select your active eSIM, and choose the top-up option to add more data.

Absolutely. Your Japan eSIM provides excellent coverage in Tokyo, Kyoto, Osaka, and Hiroshima.
