How to Get Japan eSIM When Traveling

Planning a trip to Japan? You must be so excited about your upcoming trip to Japan! From the vibrant streets of Tokyo to the peaceful temples of Kyoto, there’s so much to see and do. One thing you’re definitely making sure to handle ahead of time is your Japan eSIM. You know you don’t want to be without data while exploring, and with the eSIM, you’ll be all set to stay connected. It’ll be perfect for sharing updates with your friends, whether it’s posting pictures of cherry blossoms or letting everyone know about your latest foodie discoveries. No more hunting for SIM cards in every city—you’ll be good to go with just your eSIM. It’s going to be so easy, and you can focus on enjoying every moment of your adventure!

When choosing the right Japan eSIM, you should consider the following factors:

1. Check if Your Phone Supports eSIM
2. Choose the Right eSIM Plan
3. Purchase and Install the eSIM

Check if Your Phone Supports eSIM

Before you start looking for an eSIM plan, make sure your phone must be:

Carrier-Unlocked Device: Your phone must be unlocked, meaning it's not tied to any specific carrier or contract. If you purchased your phone outright (without any carrier agreement), it’s likely unlocked. However, if you're unsure, it's a good idea to contact your carrier and double-check. An unlocked device allows you to use eSIM profiles from different providers without any issues.

eSIM-compatible: Most smartphones released after 2018 are eSIM-compatible, but it’s important to verify that your particular model supports eSIM. Depending on your location and carrier, this can vary. You can easily check your phone’s eSIM compatibility by looking it up on the manufacturer’s website or checking the full list of eSIM compatible devices provided by ChillaxSIM. If your phone supports eSIM, you’ll be able to activate it and enjoy connectivity in Japan.

Choose the Right eSIM Plan

When choosing the right Japan eSIM, there are three key factors to consider：

1. Carrier Network Coverage：KDDI (au) is one of Japan's largest mobile carriers, and it offers extensive network coverage across the country.KDDI’s au network provides coverage across nearly all of Japan, including major cities, suburban areas, and even remote or rural regions. KDDI is known for its reliable service, making it a great option for travelers who plan to visit both urban hotspots (like Tokyo, Osaka, and Kyoto) as well as more off-the-beaten-path destinations.Please check the KDDI network coverage map in Japan here.When you use an eSIM like ChillaxSIM that partners with KDDI, you can expect robust coverage throughout Japan. Whether you’re in a bustling city, a quiet suburban neighborhood, or exploring Japan’s remote countryside
2. Duration of Your Trip: Consider how many days you’ll be spending in Japan. ChillaxSIM offer plans with a specific validity period, such as 7 days, 14 days, or 30 days. Be sure to choose an eSIM that aligns with the length of your trip. You don’t want to overpay for a plan that lasts longer than you need, but you also don’t want to run out of data early.
3. Data Usage: Think about how much data you’ll need during your stay. If you’ll mainly use your phone for navigation, social media, and messaging, a smaller plan (e.g., 1GB or 3GB) might suffice. For heavier users who plan to stream videos, make calls, or use a lot of data for work or entertainment, you should look for a larger data plan (e.g., 10GB or more). In addition to the above data packages, ChillaxSIM also offer unlimited data plans.
