Aichi eSIM.
Central Japan's industrial heart — Nagoya's castle and miso-katsu, plus timed-entry Ghibli Park in Nagakute.
Aichi eSIM plans: unlimited, or by the GB.
Every Aichi eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Aichi — you can always top up or switch on your next trip.
Unlimited plansHigh-speed data, nothing to count
Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.
- Best for streaming, video calls & hotspot
- Great for longer or open-ended trips
- One price per day — no GB anxiety
A set bundle, brilliant value
A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
- Best value for lighter, shorter trips
- Clear allowance — pay only for what you need
- Top up any time from your phone
How much data do you need in Aichi?
A rough, honest guide to sizing your Aichi eSIM so you're not guessing. Most travellers in Aichi are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.
Everything above plus social scrolling, music, cloud photo backups and a little video. Where most travellers land.
Netflix by the pool, long video calls home and hotspot for the laptop — go Unlimited and stop counting.
Aichi eSIM: your local data guide.
Aichi centres on Nagoya — its golden castle, Atsuta Shrine and hearty miso-katsu — then spreads to the timed-entry world of Ghibli Park in Nagakute, hilltop Inuyama Castle and the autumn maples of Korankei gorge. An Aichi eSIM keeps Meitetsu train times, Ghibli Park tickets and directions running as you move between city and countryside.
Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
Where you'll lean on data in Aichi.
Central Nagoya, its subway and the Sakae district run fast 5G, smooth for maps and mobile payments.
You'll want live data here for timed-entry tickets and the Linimo maglev line; coverage is solid.
The castle town and riverside hold steady 4G, fine for navigation and cormorant-fishing bookings.
This maple gorge gets busy in autumn and signal can slow under crowds, so load directions in advance.
Getting around Aichi on your eSIM.
- Meitetsu Train Info— Nagoya's private rail app covering routes to Inuyama and Centrair airport.
- Japan Travel by NAVITIME— English planner for Nagoya's subway, JR and the Linimo to Ghibli Park.
- GO— Book taxis across Nagoya and the wider Aichi area.
- Mobile Suica— Nationwide IC card that taps onto Nagoya's subway and city buses.
Two to three days suits Aichi — a day for Nagoya's castle and cuisine, a day at Ghibli Park, and time for Inuyama or Korankei.
Two or three days of subway maps, Ghibli tickets and photo sharing fit comfortably in a balanced 3-5 GB; go Unlimited only if you plan to stream or tether.
Nagoya and its suburbs deliver fast, reliable 5G, and Ghibli Park is well served; coverage is thinner and can slow under crowds out at Korankei gorge and the rural hills.
