Why You Need an eSIM for Japan

Japan's rail system can be pretty complex. You'll really need apps like Google Maps and Japan Transit Planner to get around.
Lots of Japanese restaurants use online platforms for reservations, like Tabelog and Hot Pepper. Plus, menus are often only in Japanese. Google Translate's camera mode is a lifesaver for reading kanji on signs, menus and vending machines.
Sure, you can find free Wi-Fi at some stations and convenience stores. But it's often spread across different providers. You'll end up logging in again and again. An eSIM gives you reliable all-day data. You won't have the hassle of renting a pocket Wi-Fi device at the airport. You also won't need to carry extra hardware around. From scanning QR codes at temples to checking Shinkansen schedules, you'll use data a lot.

Network Coverage in Japan

Your eSIM will connect to all four major Japanese carriers: KDDI, SoftBank, Rakuten and NTT docomo. You'll get great 5G and 4G LTE coverage all over the country. Big cities like Tokyo, Osaka, Kyoto, Hiroshima, Fukuoka, Nagoya, Sapporo and Yokohama generally have strong signal.
The Shinkansen bullet train network keeps you connected for most of your trip. Even on longer routes, say from Tokyo to Hiroshima, you'll usually have signal. You'll find pretty solid 4G coverage on major highways and suburban rail lines. Even lots of rural areas and smaller cities usually have good signal.
Japan's mobile network is one of the best out there. You might only hit occasional coverage gaps in very mountainous spots, like deep in the Japanese Alps. Remote islands far from the mainland could also be a bit patchy.

Connectivity Tips for Japan

  1. Japan's rail system is complex. You'll need real-time data for checking platform numbers, transfer times and delays, so keep your eSIM active while moving around.
  2. Google Translate's camera mode is really helpful for reading Japanese menus, train station signs and vending machine options. It works in real-time and is probably the most useful app you'll use in Japan.
  3. Don't bother with a pocket Wi-Fi router rental at the airport. Your eSIM is way simpler, lighter, doesn't need charging and works better for daily use all over Japan.
