Cherry blossoms, ancient temples, and bullet trains, stay connected in Japan.
Get the best eSIM for Japan. Excellent coverage with the best carriers available. Unlimited data options, instant QR activation & no roaming fees. Perfect for Tokyo, Kyoto & Osaka.
Planning a trip to Tokyo, Kyoto or Osaka? JamboSim's esim japan plans use SoftBank and KDDI (au), with options from $1.99 and Unlimited plans available. Connectivity is generally strongest in cities and populated areas, making mobile data useful for checking train routes, translating menus and finding your hotel. Reception can vary in mountainous countryside, remote locations and tunnels, so download essential maps and save accommodation details before heading farther afield.
Choose a plan around your daily routine rather than just your trip length. For occasional messaging, navigation and restaurant searches, compare the available data allowances with your expected usage. If you expect to use data frequently, consider Unlimited: it includes 3 GB of high-speed data per day, followed by speeds of about 1 Mbps until local midnight. Hotspot is allowed, so you can share your connection with a laptop or travel companion, while keeping shared usage in mind.
Install your esim japan plan over Wi-Fi before departure, then enable data roaming for the eSIM line when you arrive to connect. Check that your phone supports eSIM and is carrier-unlocked before purchasing. These plans are data only, so use internet-based messaging and calling apps rather than relying on traditional calls or SMS. WhatsApp keeps your own number.

A top-up lets you add more data to your existing eSIM without installing a new profile. If your plan supports top-ups, you simply purchase additional data through JamboSim and it's added to your current eSIM instantly - no new QR code needed. Not all plans support top-ups; you can check this in the plan details before you buy. If your plan doesn't support top-ups, you'll need to purchase and install a new eSIM when your data runs out.
