I've the apk file if you're interested; Here. I've test install on my phone and it's real. Although, you'll need to register first to be eligible as beta tester to actually get in. How? No idea, since I didn't register, maybe through http://www.pokeland.jp/ Oddly enough, there exist a game called 'Pokeland Legends', a fan made open world android game; https://www.facebook.com/pokemondsland/. If interested, click on the 'Play Game' button provided inside the link to download the app installer for android. It's F2P as far as I have noticed. But I've not tried, so no idea.
