I tried API based on the document https://developers.google.com/speed/docs/insights/v5/get-started?hl=en
It gives "emulatedFormFactor": "desktop"
Is there anyway to change it to mobile?
I'm expecting something like below in web-app
There, we can change device by querying tab=mobile or tab=desktop
You are looking for strategy and this accepts either "desktop" or "mobile".
So in the example you gave it would be:-
It appears you also wanted it to be in Japanese if I understand correctly?
To use different languages / local formatting you would append locale.
So add &locale=ja for Japanese I believe. This is the equivalent of hl=JA in the URL you posted.
