I found a reference to this on the shogi board, but it was a year old with no reply:

It would be really nice if, when playing shogi with the traditional piece set, the promotion piece was also shown as traditional and not western.

(The other thing mentioned there is that would be nice would be for "Japanese Chess" to be renamed to Shogi throughout the site. It seems to be half done at the moment, with some references to Shogi and others to Japanese Chess.

Apart from that, it's perfect!
