Google Play Newsstand's paid content has been forging its way around the world, trying to catch up with the various Play entities that preceded it. Today marks its arrival in three new countries in East Asia: Japan, Malaysia, and Thailand.
The news was mentioned on Google Play's Twitter stream, and indeed, after checking the country availability support page for Play digital content, we can see that Malaysia and Thailand are both now on the Newsstand list (they weren't there on September 8th) but Japan is still missing. It's either a small error or the service is coming to the country but isn't quite live yet. Either way, residents of both countries should now or soon have access to paid magazines and subscriptions in the Newsstand app.
The tweet also mentioned Play Music coming to Japan, but we'd already discovered that back on September 3rd from an update to the same support page. This makes it official though.
