You might have noticed that when you have created your Japanese iTunes Store account, a lot of the music have romanized song titles and artist names. Now of course, to some, this is a big plus, but for people who are picky and like to use the correct tags, there is a solution. It’s a simple fix, actually all you have to do is launch iTunes in Japanese. Doing so also adds new functionality to iTunes which I’ll show you further down in this post.
This is a tutorial for iTunes on Mac OS X Snow Leopard, if you know how to do this on Windows, please let me know in the comment section at the end of this post and I’ll gladly add a tutorial for Windows users too. Also, if you don’t yet have a Japanese iTunes Store account, you can follow these instructions provided by austrian otaku to create one without needing a credit card or gift card.
UPDATE (February 7, 2010): This tutorial shows you how to do this without any third-party applications. There is an even simpler solution to do this, and that is by installing an application called Language Switcher. The application is very easy to understand, just launch it, select iTunes and the language you want to launch it in. Just like in the tutorial below however, this is not a permanent change, you have to repeat the procedure every time you relaunch iTunes. Thanks to Jenny (see comments section) for letting me know about this application!
UPDATE 2 (February 7, 2010): To do this on Windows, you simply just have to go into the settings of iTunes, change your language, relaunch iTunes and log in and out with your Japanese iTunes Store account. (Screenshot) Thanks to austrian otaku.
