Pokemon-go – A pokestop wont turn blue after many hours

The reason its not working is because I am in Japan and it has not been made available for Japan yet.

I was able to download and get my starter but the actual wild Pokemon are unavailable. Why it allows me to get that far, I'm not sure.

Edit: Pokemon-Go works in Japan as of 2016/07/22 No need for anything that I had mentioned as possible solutions in the question.

Thank you for your answers @TimPenner @KevinTian. I actually found a neat way to get around this when I was browsing Reddit.

There's an app called Caffeine which prevents the phone from going to sleep (lock screen) whenever a certain application is in use (Pokemon Go). Instead it dims the screen after the timeout period that usually would cause the phone to go to the lock screen.

So now when I go jogging and I put the phone in my pocket it will stay on indefinitely plus it dims the screen after the 1 min timeout period to save battery.
