Hey there, people who live in the Land of the Rising Sun, who end their day when we're about to start ours, and who have brought plenty of appreciated contributions to our modern lives, like sushi and mangas. Now is your time to receive a small export of Western society, in the form of Google Play Music access.

Both support pages for Google Play's paid purchases and country availability for apps and digital content have received a recent update to add Japan to their lists. This means that Android users in Japan should either already or soon have access to Play Music and Play Music All Access so they can individually purchase songs and albums or pay a monthly fee for unlimited access to thousands of tunes. Ongaku tanoshindene!*
