eSIM vs Roaming Fees in Japan

Whilst in Japan, mobile operator roaming allows you to keep your existing SIM and phone number. However, if you do this, you are likely to be hit with high daily roaming fees that can quickly add up. Your carrier may also put in place daily data limits and speed restrictions once you have exceeded your allowance.

Through our travel  eSIM data plan, Cedar Mobile gives you a set amount of data at a fixed cost. You can also install the eSIM on your phone without having to take out your physical SIM card, 

Our post on why Cedar Mobile, dare to compare provides more details to help you pick the right option for you.

Travelling on to Korea or wider Asia

If you want to tour other countries in Asia besides Japan, we can help you stay connected through alternative plans.

Consider choosing our China, Japan and Korea eSIM for a combined trip to those destinations. You can also buy a separate South Korea eSIM or use our Asia 20 countries eSIM if your travels are taking you to multiple countries.

Japan travel guides

Once you have sorted your eSIM, why not gain some inspiration from our Japan travel guide 2026 and Japan travel tips 2026.

Cedar Mobile offers a Japan eSIM that provides reliable network coverage with high-speed data across the country. 

Free public Wi-Fi is widely available in Japan. However, it might not always be secure, and internet access in remote areas can be patchy. For this reason, you might want to get Cedar Mobile’s Japan eSIM for your phone. It will provide you with reliable, high-speed coverage whenever you need it throughout most of the country.

If you have a compatible dual-SIM phone, you can keep your home SIM active to receive phone calls and select Cedar Mobile’s Japan eSIM for data. Be mindful that mobile carrier roaming charges may still apply to any calls or SMS.
