Skipped the airport counter, or just want a better deal? Here’s where to find prepaid SIMs in Tokyo’s two biggest hubs.
Why Look Beyond the Airport
Airport counters are built for convenience the moment you land, and that convenience comes at a cost — similar to how airport currency exchange rates tend to be weaker than what you’ll find in the city. If you didn’t set up connectivity at the airport, or want to compare a few options before committing, both of these neighborhoods give you that room.

Where to Look
Large electronics megastores — dedicated mobile and SIM sections, with staff who are often multilingual given the tourist-heavy neighborhoods
Specialty prepaid SIM counters — smaller, travel-focused shops that deal specifically in short-term plans for visitors
Convenience stores — some carry prepaid SIM cards directly on shelves, no counter or conversation needed, though the selection is more limited than a dedicated shop
Shinjuku vs Shibuya: Is There a Real Difference?
Not really, in terms of pricing or selection — both neighborhoods are dense enough to offer solid options. The more honest answer is that this comes down to convenience: pick whichever neighborhood you’re already planning to spend time in, rather than making a special trip to one over the other.
What to Compare Before You Buy
Data-only vs. voice + data — data-only plans are cheaper and enough for most travelers who rely on messaging apps for calls
Validity period — make sure it comfortably covers your full trip length, not just the days you’re in Tokyo
Data allowance — check whether it’s a fixed cap or unlimited with speed throttling after a threshold
Our Recommendation
If you already set up an eSIM before your trip, you likely don’t need any of this — that’s still the fastest path for most travelers. If you skipped it or need a physical SIM, either neighborhood works fine; there’s little reason to treat this as a comparison shopping trip on its own.
