eSIM Travel Tips for Tokyo
Install your eSIM before your long-haul flight from Heathrow
British Airways and Japan Airlines fly direct from London Heathrow to Tokyo Narita and Haneda. Install your HelloRoam Japan eSIM on Wi-Fi at home before you board.

Load Suica onto your iPhone Wallet before you land
You can add a Suica IC card to Apple Wallet before landing in Japan. This lets you tap through Tokyo Metro, JR lines, and convenience store payments without queuing for a physical card at the airport.
Carry cash for smaller restaurants and traditional areas

May and June are pleasant before the July and August heat and humidity. July and August are hot and humid at 28C to 34C with occasional typhoons. December through February is cold (3C to 10C) but clear, with no crowds and the best flight prices.

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.
