When traveling in Japan, there are many opportunities to use Google Maps to check routes to stations and tourist spots, or to search for restaurants. Therefore, you may be wondering, "How much data does Google Maps use?" "Is a 3GB or 5GB eSIM sufficient?"
In reality, Google Maps is not an app that consumes as much data as video streaming services or social media. However, the data usage can vary depending on how you use it, so it is important to choose the eSIM capacity that fits your travel style.
In this article, we will explain the approximate data usage of Google Maps and provide guidelines on the necessary eSIM capacity for traveling in Japan.

Points to Note When Using Google Maps
While Google Maps is relatively low in data usage, to use it comfortably during your trip, make sure to check the following points.
