We've covered Jisho, the Japanese to English dictionary for OS X, a few times in the past, so I'm pretty sure that everyone who wants to translate Japanese to English and reads our site has probably seen it already. But just in case you've been waiting on a decision to buy it, wait no more-- not only has James, the creator, recently updated the app to version 2.2 (with Leopard compatibility, results sorting, and a greatly enhanced zooming function), but he's also putting it on sale for TUAW readers: between now and Sunday, December 9th, use the code "TUAWFTW" during checkout, and get the $15 app for 20% off.
Newly updated software and a discount just for you readers? Kirei desu! Sore kudasai!*
*Note: The author of this post does not know Japanese and does not own Jisho. For all he knows, he just said that "You have a nice chicken."
