Make a Japanese iTunes account. There’s a guide online on how to fill out the page and how to get a Japanese address. Then go to playasia and get a Japanese iTunes digital credit code. 1000 is enough and you’ll be able to get about 4 songs with it. They’ll email you the code Straight away and it should be pretty.simple from there as the Japanese iTunes.will be in English. To change to Japan iTunes go onto the music store and scroll to the bottom of the page and you can change there.Sorry if this is a tad hard to follow. Typing from my phone.
