Practical guides / Japan connectivity

Choose your Japan internet setup with fewer surprises.

Start with the decision that matches your trip: compare connection types, plan for a group, or check whether each phone can use an eSIM.

Choose by device compatibility, group movement and who needs an independent connection.

Work out when one shared router is enough and when a second connection prevents problems.

Confirm eSIM support, carrier unlock status and activation requirements before buying.

Turn the guidance into a trip estimate

Once you know which devices and subgroups need a connection, use the planner to compare only the setups that can actually keep everyone online.
