Testing the Map Forecast API with trial key, I am unable to change the language, specifically to Japanese. Using the following options.
const options = {
// Optional: Initial state of the map
lat: 50.4,
lon: 14.3,
zoom: 5,
lang: '日本語',
};
Have also tried lang: 'jp' and lang: 'Japanese' with no changes to map or menu language. Am I using the correct lang setting for Japanese, are language other than English not possible with trial key?
