Why you need an eSIM in Tokyo
270+ subway stations to navigate
The Tokyo Metro and Toei lines run 270+ stations across 13 lines. Google Maps transit is non-negotiable for getting between them — and live data handles the real-time platform changes and delays that offline maps can't.
Real-time translation, everywhere
Menus, train boards, ticket machines and signage are largely in Japanese. Google Translate's camera mode reads them live — convenient, but it needs a steady connection to keep up as you point your phone around.
No queue at the airport counter
Narita and Haneda SIM counters back up to 20–40 minutes after wide-body arrivals. An eSIM activates from home before you fly, so you're online before you reach baggage claim — no counter, no plastic SIM swap.
How much data will you use?
Estimated daily usage for a typical Tokyo sightseeing trip.
| App / use case | Est. daily data |
|---|---|
| Google Maps — subway + walking navigation | 200–400 MB |
| Google Translate — camera mode | 100–200 MB |
| Instagram / TikTok | 300–800 MB |
| Streaming music (Spotify) | 100–150 MB |
| Search + general browsing | 100–200 MB |
| Tabelog / restaurant search | 50–100 MB |

Heavy social or video streaming can push usage to 3–5 GB/day. An unlimited plan removes the counting entirely.

Does a Japan eSIM work on the Tokyo Metro?▾
Yes. KDDI and NTT DOCOMO have the deepest underground infrastructure in Tokyo. Most Tokyo Metro and Toei Subway stations have mobile coverage, and the signal holds between stations on the main lines. Japan Wireless eSIM runs on both KDDI and DOCOMO.
Can I get an eSIM at Narita or Haneda airport?▾
Physical SIMs are sold at airport counters, but the queue is 20–40 minutes on busy arrival days. A Japan Wireless eSIM activates before you fly — scan the QR code from home, and your phone connects to KDDI or DOCOMO automatically when you land.
How much data does a typical Tokyo trip use?▾
Most Tokyo visitors use 1.5–3 GB per day. Google Maps navigation, Google Translate camera mode, Instagram, and streaming music account for the bulk. A 7-day unlimited plan removes all data counting for a standard trip.
Is 5G available throughout Tokyo?▾
Yes. Tokyo has extensive 5G across all 23 wards, both airports, and major transit hubs including Shinjuku, Shibuya, Akihabara, and Tokyo Station. Japan Wireless 5G plans run on KDDI's 5G network in Tokyo.
Can I use hotspot in Tokyo with a Japan eSIM?▾
Yes. Japan Wireless supports hotspot and tethering. Share your 5G connection with a laptop or travel companion's device — useful for working from cafes or navigating with a tablet.
