The Typing of the Dead
or this:
King Grammar and the Alphabet Castle (MAD TV)

Looks very very close to Typing.

 

Yep and it was real good fun too, even more so than the HOTD games. Sadly it killed two Dreamcast keyboards from me typing to fast and hard. There was also gonna be a Space Harrier Typing game for the PC but I think it got cancelled.

 

Looks like it could be playable for English gamers as the words already come up in English (ala Typing) so you just need to write down the word you see instead of seeing it in Japanese and figuring out what it means. Might be a bit frustrating when it doesn't recognise certain letters though and you got a crap load of zombies after your ass.

 

The concept sounds funny, or even hilarious. Might be fun to give a try if it's playable without knowing japanese, but it's definitely not the kind of game I'd play for hours at a time.
