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.

On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
