OK, so maybe Katakana Kitten isn't your new favorite tumblr, but it's definitely mine.
Why? A quick look at this unique tumblog's description should help explain things: "Hellow, I'm Midori. I know some Japanese. This blog posts one example of katakana usage a day, usually from video games. Please use these posts to bolster your own Japanese studies."
Here's a recent example of the kind of content Midori has published on Katakana Kitten since the tumblog debuted last December:
She always follows up the screenshot and katakana sample with a short blurb about the game in question, too. Here's the text she typed up for Clock Tower:
"A noteworthy point-and-click horror game originally made for the Super Famicom, developed by Human Entertainment, 1995. Much of the game’s content and style was inspired by the work of horror film director Dario Argento."
In other words, not only can Katakana Kitten help boost your Japanese language abilities, but it also can broaden your knowledge of Japanese video games. Now if we could just convince Midori to start a second tumblr devoted to hiragana or even kanji usage in games...
