Installing a Japan eSIM is simple — just scan the QR code after purchase. Takes less than 90 seconds.

We recommend installing before departure so you connect automatically upon arrival. Supports major iPhone, Samsung, and Google Pixel models.

Where does this eSIM work in Japan?

The Japan eSIM connects to major local carriers (NTT Docomo, SoftBank), covering all of Japan.

From Tokyo's Shibuya to Kyoto's Golden Pavilion, from Osaka's Dotonbori to Hokkaido's snow landscapes — enjoy stable connectivity in cities and rural areas alike.

Japan's 4G/5G coverage is among the world's best, with good signal even on the Shinkansen.

Japan is one of the fastest countries for mobile internet globally. You can experience 5G or 4G LTE in most areas.

Urban areas typically offer download speeds of 100-500Mbps — more than enough for video calls, live streaming, HD map navigation, and all your favorite apps.

How much data do I need for traveling in Japan?

Common data usage scenarios in Japan:

• Google Maps/Apple Maps navigation

• Restaurant and attraction searches
• Social media photo sharing

We recommend 1-2GB per day. For heavy navigation and video call usage, consider 3GB+ plans.
