Travel guide: Japan
Japan pairs spotless megacities with quiet temples, hot springs and a food scene many people travel for alone. First-time visitors are often surprised by how smoothly everything works – as long as their phone is online.

Mobile internet in Japan
Japan’s mobile networks are among the best in the world: 4G covers practically the whole country and 5G is available in every major city – the connection even holds up in subway tunnels and on the Shinkansen. Free Wi-Fi exists at stations and convenience stores, but it usually requires registration and is time-limited.
With an eSIM you are online as soon as you land and there’s no pocket Wi-Fi router to collect. Essential apps: Google Maps for train connections including platform numbers, a translation app with camera mode for menus, and a timetable app for the Shinkansen.
Highlights in Japan
Tokyo
Neon-lit Shinjuku, the Shibuya Crossing, Meiji Shrine and countless neighbourhoods with a character all of their own.
Kyoto
More than a thousand temples and shrines, the red gates of Fushimi Inari and the Arashiyama bamboo grove.
Hakone and Mount Fuji
Onsen baths with views of the sacred mountain – an ideal stop between Tokyo and Kyoto.
Hiroshima and Miyajima
The moving Peace Memorial and the famous “floating” torii gate in the sea.
Practical travel tips
- Cash matters less than it used to, but small restaurants, temples and vending machines often take yen only. Convenience store ATMs reliably accept foreign cards.
- A rechargeable IC card (Suica, Pasmo or ICOCA, also available in your phone’s wallet) saves buying tickets for trains and buses.
- Is a Japan Rail Pass worth it? Only for lots of long journeys – for Tokyo–Kyoto–Tokyo, single tickets are often cheaper.
- Cherry blossom season (late March to early April) and autumn colours (November) are magical but busy: book accommodation early.
Do’s
- Take off your shoes before entering homes, ryokan and some restaurants.
- Keep one side of the escalator free (stand on the left in Tokyo, on the right in Osaka).
- Carry your rubbish with you – public bins are rare.
- When paying, place cash or card in the small tray at the till.
Don’ts
- Don’t tip – it is usually returned politely.
- Don’t make phone calls on trains, and switch your phone to silent.
- Don’t eat while walking, and never stick chopsticks upright in rice.
- Don’t enter an onsen or public bath with visible tattoos without asking first.
Entry, visa and safety: please check your government’s current travel advice before you go. Last updated: October 2026.
Japan eSIM – frequently asked questions
Which Japan eSIM plan do I need?
That depends on how much data you use: for navigation, messaging and occasional browsing 1–3 GB per week is usually enough; for social media, video calls or hotspot rather 5 GB or more. The plans cost between €3.99 and €38.99.
When does the validity of my eSIM start?
Validity only starts when the eSIM connects to a network at your destination for the first time. So you can safely install it before your trip.
Will my normal phone number stay reachable?
Yes. This is a data-only eSIM installed in addition to your SIM card. Calls and SMS still use your normal number – mind your provider’s roaming prices.
Does the eSIM work with my phone?
Your phone must support eSIM and be carrier-unlocked. This includes all iPhones from XS/XR, Samsung Galaxy from S20 and Google Pixel from 3. See “Compatible devices” for the full list.
How do I set up the eSIM?
After purchase you receive a QR code by email. Scan it in your phone’s mobile network settings, select the eSIM for mobile data and switch on data roaming for the eSIM at your destination.
Do I need to set an APN?
Yes. After installation, enter the APN wbdata in the eSIM’s mobile network settings. We show you how, step by step, after your purchase.
