eSIM Travel Tips for Tokyo

Activate your eSIM before you leave Changi
Buy your HelloRoam eSIM for Tokyo before your flight from Singapore Changi Airport. Scan the QR code at home on Wi-Fi, enable data on arrival, and you are connected in Tokyo without searching for a local SIM card at the airport.
Keep your Singapore number active on dual SIM
On a dual SIM device, keep your Singtel, StarHub, or M1 SIM active for calls and texts from Singapore. Set HelloRoam as your data line for Tokyo. Family and colleagues in Singapore reach you on your regular number without international charges.
Download offline maps before your flight
Download Google Maps or Maps.me offline for Tokyo before leaving Singapore. This saves data on detailed map downloads and keeps you covered in areas with weaker signal during your first hours in Tokyo.
Set up Suica IC card before your first train ride
The Suica digital card on iPhone and select Android phones loads transit credit and pays at convenience stores. Setting it up needs a live data connection. Your HelloRoam eSIM handles this on the N'EX from Narita or the Keikyu from Haneda before you reach your hotel.
Book popular restaurants in advance
Popular Tokyo restaurants on Tabelog and through hotel concierge services fill up weeks in advance. Check reservation apps using your HelloRoam data connection from Singapore before departure to secure top sushi and ramen spots.

Best time for Singapore travellers to visit Tokyo

Tokyo has two peak travel seasons for Singaporeans. Cherry blossom (sakura) season from late March to mid-April draws the largest crowds to Ueno Park, Shinjuku Gyoen, and the Meguro River. Autumn foliage (koyo) from mid-November to early December is the second peak. Avoid Golden Week in late April through early May if possible, as domestic crowds are enormous. Singapore Airlines and Japan Airlines fly SIN-NRT and SIN-HND year-round.

Airport and Transit Connectivity

Tokyo has two main airports. Narita International Airport (NRT) is 60 kilometers from the city center 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.

Singapore-based travellers should activate their eSIM before departure so data is ready on arrival.
