eSIM Travel Tips for Tokyo
Sort your eSIM before you leave Dublin
Buy your HelloRoam eSIM for Tokyo at home, scan the QR code over Wi-Fi, and switch on data when you land at Tokyo Narita International Airport (NRT) or Haneda Airport (HND). You step off the plane already connected on local 4G LTE. No queuing at airport telecom shops.
Keep your Irish number live
On a dual-SIM phone, leave your Three Ireland, Vodafone Ireland, Eir, or GoMo SIM active for calls and texts. Use HelloRoam for data in Tokyo. People back home can still ring your Irish number without international charges.
Download offline maps first
Save Google Maps or Maps.me for Tokyo offline before you fly. Offline navigation uses no data and keeps working even where signal is patchy. It's a handy backup when you arrive and need directions quickly.
Watch your data usage
The HelloRoam app shows your balance in real time. You get alerts at 80% and 95% usage so there are no nasty surprises. Top up inside the app if you need more data in Tokyo, no reinstall needed.
Save emergency numbers offline
The emergency number in most countries is 112. In Tokyo it is worth checking the local number too. Save these offline before you travel. Emergency calls work on any available network regardless of your HelloRoam data balance.

Best time to visit Tokyo from Ireland
Tokyo is a popular destination for Irish holidaymakers. Dublin Airport has regular direct or connecting flights year-round. The best time to visit depends on your preferences for weather, crowds, and value.

Airport and Transit Connectivity
Tokyo has two main airports. Narita International Airport (NRT) is 60 kilometers from the city centre and connects via the Narita Express (N'EX) to Shinjuku in 80 minutes, or the Limousine Bus to various hotels.
Haneda Airport (HND) is 20 kilometers away and connects via the Keikyu Line to Shinagawa in 20 minutes, or the Tokyo Monorail to Hamamatsucho. Both airports have 4G and 5G throughout their terminals.
IC Suica and Pasmo cards for metro travel can be bought at airport kiosks or set up as digital cards with a live data connection. The Tokyo Metro, Toei Metro, and JR lines all have coverage and the Metro navigation app works smoothly on mobile data.
Irish travellers should activate their eSIM before boarding so navigation apps work as soon as they land.
