There aren't many anime that focus on kendo, the most famous one being a series from the early eighties: Musashi no ken (lit. "the sword of Musashi"). Another, much more recent one, from the fall of 2007 is Bamboo Blade. The screenshot above is from the show, ridiculing one of the commonly known aspects of kendo: kendoka and their equipment stink, especially during summer (^_^);.

Bamboo Blade really isn't that good: I'd qualify the art as meh, the story as generic (though it's growing on me after a few episodes) and the animation as crude. But still, it's about kendo, it does a fair job of portraying shiai and it conveys the enthusiasm kendoka have for their sport pretty well!
