Internet speed in Japan with an eSIM from Vlex eSIM is generally very fast thanks to advanced 4G and 5G networks. You can comfortably stream videos, make video calls, and use social media without interruptions.
Most modern smartphones, such as iPhone XS and newer, as well as many Android devices that support eSIM, are compatible with eSIM in Japan. Check your device settings for an eSIM or digital SIM option before your trip.
Internet coverage in Japan’s main tourist destinations, such as Tokyo, Kyoto, and Osaka, is excellent. Major operators provide a stable connection even in many rural and remote areas, so you can stay connected while sightseeing.
To activate an eSIM in Japan, simply scan the QR code provided by Vlex eSIM and follow the on-screen instructions. This is much more cost-effective than traditional roaming, helping you save on mobile data while enjoying local-style rates.

Japan is a country of cutting-edge technology, unique culture, and stunning landscapes, from the bustling streets of Tokyo to the tranquil gardens of Kyoto. To always stay connected, share your experiences, and find your way in unfamiliar places, you need reliable internet. With an eSIM from Vlex eSIM, you can forget about complicated roaming options and searching for local SIM cards.
Roaming from Russian operators in Japan can be quite expensive, and local SIM cards take time to buy and activate. You have to look for them in stores, show your passport, and figure out plans in Japanese. With an eSIM from Vlex eSIM, you get internet access immediately upon arrival — no queues and no hassle.
If you plan to stay in Japan for 7–14 days and actively use the internet for social media and navigation, we recommend a 3–5 GB package. For video streaming and video calls, a 10 GB plan or an unlimited Day Pass will work better. To calculate your data needs more precisely, use our calculator on the homepage.
eSIM is supported by devices such as: iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+, Huawei P40 Pro, and most modern smartphones. Make sure your phone is unlocked before making a purchase.
