AI-generated Key Takeaways
- 
          Customize your map by adjusting the default language and specifying a region code for tailored behavior. 
- 
          Utilize the languageparameter in the script tag to display map information in a specific language, overriding browser settings if needed.
- 
          Apply the regionparameter in the script tag to refine map tiles, bias application results, and ensure compliance with local laws.
- 
          For optimal results and legal adherence, consider setting both languageandregionparameters when localizing your map.
You can customize your map for a specific country or region in the following ways:
- Change the default language settings.
- Specify a region code, which alters the map's behavior based on a given country or territory.
Language localization
By default, the Maps JavaScript API uses the user's preferred
  language setting as specified in the browser, when displaying textual
  information such as the names for controls, copyright notices, driving
  directions and labels on maps. In most cases, it's preferable to respect the
  browser setting. However, if you want the
  Maps JavaScript API to ignore the browser's
  language setting, you can force it to display information in a particular
  language by adding a language parameter to the
  <script> tag when loading the
  Maps JavaScript API code.
The language parameter affects the names of controls, copyright
  notices, driving directions, and control labels, as well as the responses to
  service requests. The effect on services is not as apparent. For example, when
  geocoding street level addresses the country name is returned in the language
  you requested, but the rest of the address will be specific to the location
  you are geocoding. On the other hand, postal and political results are
  returned in the requested language.

  this demo to experiment with the changes on the map when you update the
  language parameter.
The following example displays a map in Japanese and sets the region to Japan:
<script async
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&loading=async®ion=JP&language=ja&callback=initMap">
</script>If you set the language of the map, it's important to consider setting the region too. This helps ensure that your application complies with local laws.
Note: When you load the API in the manner shown above, the map uses the Japanese language for all users regardless of user preferences. Be sure you want this behavior before setting this option.
The Maps JavaScript API also supports bi-directional
  (Bidi) text containing characters in both left-to-right (LTR) and
  right-to-left (RTL) languages natively. Examples of RTL languages include
  Arabic, Hebrew, and Farsi. Generally, you should specify RTL language pages to
  render properly by adding dir='rtl' to the page's
  <html> element. The following example renders a map of
  Cairo, Egypt using Arabic controls:
<script async
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&loading=async®ion=EG&language=ar&callback=initMap">
</script>See the list of supported languages. Note that new languages are added often, so this list may not be exhaustive.
Region localization
Add a region parameter to the <script> tag
  when loading the Maps JavaScript API code, if you
  want to alter your application to serve different map tiles or bias the
  application (such as biasing geocoding results towards the region).
As the developer of a Maps JavaScript API
  application you are encouraged to always set a region parameter as various services
  (such as Places Autocomplete) tend to provide better results when the region is set.
  It is also your responsibility to ensure that your application complies with local laws by
  ensuring that the correct region localization is applied for the country in which the application
  is hosted.
The region parameter accepts
  
    Unicode region subtag identifiers which (generally) have a
  one-to-one mapping to country code Top-Level Domains (ccTLDs). Most Unicode
  region identifiers are identical to ISO 3166-1 alpha-2 codes, with some
  notable exceptions. For example, Great Britain's ccTLD is "uk" (corresponding
  to the domain .co.uk) while its region identifier is "GB." See
  Google Maps Platform Coverage Details for
  supported regions.
  Try 
  this demo to experiment with the changes on the map when you update the
  region parameter.
For example, the following script tag localizes the map to the United Kingdom:
<script async
    src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&loading=async®ion=GB&callback=initMap">
</script>The following examples show two maps, one which geocodes "Toledo" based on
  a region set to US (US) to "Toledo, Ohio" and one
  which biases results based on a region set to ES
  (Spain) to "Toledo, Spain."
