Tokyo Bay’s deep-sea berths at Honmoku and Daikoku are industrial islands with nothing walkable nearby. With your own data you can video-call home from the berth and navigate shore leave into Yokohama or Tokyo.

Coverage at the Port of Yokohama is Japan's regular mobile network — the same one locals use, reaching the terminals, the port area and the town beyond. Buy online before you arrive, install the eSIM over Wi-Fi (at home or on the ship), and you're online as soon as you're in range. The same plan keeps working across Japan and every other country it covers — check your whole route on one plan.

You don't need to. Buy this eSIM online before you arrive — it's emailed within minutes and you install it over Wi-Fi at home or on board. Data works as soon as you're on Japan's mobile networks, with plans from $9.99. No kiosk hunt on shore leave.
It works wherever Japan's regular mobile networks reach: in the terminal, around the port, and often at anchorage close to the coast. Mid-ocean is still the ship's satellite — no land SIM changes that.
Before you travel. Install the eSIM over Wi-Fi; it activates on first use and then runs for 31 days or until the data is used up — one plan can cover the flights in, the port stay and the trip home, in every covered country on your route.
