The worlds largest chess set

I'm not sure what the record for the worlds largest chess set is (real life elephants maybe) but a set made by Toyota would go close. It consisted of various models of Toyota Cars, and board was a floor of a stadium in Japan.
If you look at the video contained in the new story here, you will of course notice that are not actually playing chess, but Shogi (Japanese Chess). However I am still going to include it under the "chess" heading, as the games are quite similar, and more importantly, one of the players was Habu Yoshiharu. I have covered him in previous posts, but he is both a FIDE Master in chess, as well as being one of the strongest Shogi players in history.
And for those that are familiar with the rules of Shogi, I'm pretty sure that did not play the game exactly according to the rules, as it would have been difficult to turn the pieces over to signify a promotion being made!
