Why You Should Avoid Roaming in Japan

Most U.S. carriers charge very high roaming fees when you use data abroad. Even “international day passes” can cost $10–$15 per day, which adds up quickly during a long trip.
You may also experience:

  • Slow speed

  • Unstable connections

  • Data limits or throttling

There are much better ways to stay connected in Japan, especially for Google Maps.

Can You Use Google Maps Without Mobile Data?

Yes, but with limitations.

What works offline

  • GPS positioning (your blue dot)

  • Viewing downloaded offline maps

What does NOT work offline

  • Live traffic

  • Updated walking routes

  • Transit/timetable info

  • Searching for restaurants, shops, or attractions

  • Reviews, business hours, phone numbers

If you only need basic directions, offline maps can help. But for a smoother trip, you’ll want some form of mobile data.

Best Ways to Use Google Maps in Japan Without Roaming

1. Download Offline Maps Before Arriving in Japan

You can download maps for Tokyo, Osaka, or Kyoto before your trip.
・Steps

  1. Open Google Maps → tap your profile

  2. Select “Offline Maps”

  3. Choose the area you want

  4. Download

This is useful, but not perfect. You won’t receive live navigation updates or transit details.

2. Use Free Wi-Fi Hotspots in Japan

Japan has free Wi-Fi in.

  • Airports

  • Starbucks and cafés

  • Convenience stores (7-Eleven, Lawson, FamilyMart)

  • Major train stations

However

  • Speeds can be slow in crowded places

  • Connections can drop suddenly

  • Login screens may appear in Japanese

  • Public Wi-Fi is less secure

It’s helpful, but not reliable enough for real-time navigation.

3. Use a Prepaid eSIM (The Best Option)

The easiest way to use Google Maps smoothly in Japan—without roaming—is to use a prepaid travel eSIM.

Why a prepaid eSIM is ideal.

  • No physical SIM swap

  • Instant activation

  • Works the moment you land

  • Affordable compared to roaming

  • Uses Japan’s reliable local networks

  • Perfect for Google Maps, translations, and social media

And among all the options, RakuSIM stands out for travelers.

Why RakuSIM Is the Best eSIM Option for Japan

RakuSIM (楽sim) is a prepaid data eSIM designed specifically for visitors to Japan. It uses NTT Docomo, one of the most reliable and widely covered networks in the country.

Key Benefits of RakuSIM for Travelers

  • Instant activation by scanning a QR code

  • No registration or passport needed

  • High-speed 4G/LTE on Docomo’s network

  • Affordable plans for short stays or long trips

  • Works perfectly for Google Maps, translation apps, and YouTube

  • No contract, no hidden fees

  • Top-up options available during your stay

Example Plans

(From the official RakuSIM website)

  • 5GB / 4 days – Perfect for short city trips

  • 15GB / 5 days – Ideal for navigation + social media

  • 30GB / 8 days – For travelers who use video and frequent navigation

  • 50GB / 16–31 days – Great for long vacations or remote work

Because Google Maps uses very little data (around 3–5MB per hour of navigation), even small plans are more than enough!

Why an eSIM Is the Most Reliable Method

When using Google Maps in Japan, reliability matters. A prepaid eSIM gives you:

✔ Real-time walking directions

Subways, alleys, and dense cities like Shinjuku can be tricky. Live navigation helps.

✔ Route updates if you take a wrong turn

Offline maps can’t recalculate automatically.

✔ Access to transit schedules

Japan’s trains are extremely punctual—but also complex. Real-time data is essential.

✔ Connection in rural areas

Temples, mountains, and countryside spots may lack public Wi-Fi.
Docomo’s coverage is excellent nationwide.

How to Set Up a RakuSIM eSIM (Important Tips Included)

Setting up a RakuSIM eSIM is very easy, but there are two important things you should know before you start:

✔ You need an internet connection to download the eSIM profile

Your phone must be connected to Wi-Fi or mobile data when installing the eSIM.
The eSIM cannot be downloaded completely offline.

✔ It’s strongly recommended to install the eSIM before you travel to Japan

Many travelers forget this and try to install their eSIM at the airport, where Wi-Fi can be slow, crowded, or unstable.
Installing at home ensures a smooth setup and avoids stress right after landing.

Step-by-step Setup Guide

  1. Purchase the eSIM on the official website (https://rakusim.net/).

  2. Connect to a stable Wi-Fi network before installation.

  3. Scan the QR code you received via email.

  4. Follow the on-screen instructions to download the eSIM profile.

  5. After installation, turn off data roaming to avoid any carrier charges.

  6. When you arrive in Japan, simply turn on Mobile Data for the eSIM.

  7. Open Google Maps — it will work instantly with high-speed data.
