Localizing the Map

This example creates a map that's localized in Japanese, regardless of the user's browser settings. The region is also set to Japan, which biases the geocoding results to that region.

Read the documentation.

TypeScript

// This example displays a map with the language and region set
// to Japan. These settings are specified in the HTML script element
// when loading the Google Maps JavaScript API.
// Setting the language shows the map in the language of your choice.
// Setting the region biases the geocoding results to that region.
function initMap(): void {
  const map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      zoom: 8,
      center: { lat: 35.717, lng: 139.731 },
    }
  );
}

declare global {
  interface Window {
    initMap: () => void;
  }
}
window.initMap = initMap;
index.ts

JavaScript

// This example displays a map with the language and region set
// to Japan. These settings are specified in the HTML script element
// when loading the Google Maps JavaScript API.
// Setting the language shows the map in the language of your choice.
// Setting the region biases the geocoding results to that region.
function initMap() {
  const map = new google.maps.Map(document.getElementById("map"), {
    zoom: 8,
    center: { lat: 35.717, lng: 139.731 },
  });
}

window.initMap = initMap;
index.js

CSS

/* 
 * Always set the map height explicitly to define the size of the div element
 * that contains the map. 
 */
#map {
  height: 100%;
}

/* 
 * Optional: Makes the sample page fill the window. 
 */

body {
  height: 100%;
