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.
