The start location of the White Tiger and Blue Dragon is a bit surprising, as their diagonal slides aim towards the board edge rather than towards the center. In Dai Dai Shogi this is the other way around: the Blue Dragon starts on the left.
In one of the comments below the Japanese blog post where this game originated, the inventor states that he deliberately put those pieces in those awkward positions. His reasoning is that we see a similar tendency in Maka Dai Dai Shogi, where the Left and Right Chariots are also positioned awkwardly with their diagonal slides heading toward the edge of the board. He also cites Chu Shogi, where the steppers are stuck on the back line despite being most useful at the front. He believes that placing those pieces awkwardly in the other variants was intentional, so he placed the White Tiger and Blue Dragon similarly (and also the Vermillion Sparrow and Turtle-Snake).
He also says he accepts this might not be correct, and in a later comment says he feels the pieces can be changed around as appropriate, so I think he wouldn't mind if players tried swapping those pieces over.
