Connectivity Tips for Tokyo
Tokyo's transit system is the busiest in the world and navigation apps are essential for first-time visitors. Google Maps and Japan-specific apps like Navitime all work with your HelloRoam eSIM. The IC card Suica app on iPhone or Android lets you load transit credit and pay without a physical card.
Download the Tokyo Metro app before your first journey. Cherry blossom season in late March to early April draws massive crowds to Shinjuku Gyoen, Ueno Park, and the Meguro River. Network speeds can slow in the busiest locations during peak blossom viewing.
The Shibuya Crossing scramble intersection is extremely well-covered for photos and live streaming. Comiket at Tokyo Big Sight brings massive crowds and some network congestion at that venue.
Best Time to Visit Tokyo
Tokyo has two universally celebrated travel seasons. Cherry blossom (sakura) season runs from late March to mid-April and is the most popular time to visit. Parks including Ueno, Shinjuku Gyoen, and the Meguro River are packed with hanami (flower-viewing) picnickers. Golden Week holiday (late April through early May) brings huge domestic crowds to major attractions; plan around it or book well ahead. Autumn foliage (koyo) from mid-November to early December is the second peak season. Momiji (maple) leaves at Hamarikyu Gardens, Meiji Jingu Gaien, and day trips to Nikko turn the city and surroundings vivid red and gold. June and July bring the tsuyu (rainy season), with frequent overcast days and high humidity. August is hot and humid (30C to 35C) but packed with summer fireworks festivals (hanabi). The sumida River fireworks attract 900,000 spectators. December through February is cold (2C to 10C) with minimal crowds at major temples and shrines. Comiket (Tokyo International Anime Fair) and the Digital Art Museum are excellent winter draws.
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.
