The strategy was invented by professional player Taku Morishita for which he won the prestigious Kōzō Masuda shogi award.
By castling faster than White, the defining feature of the Morishita System also becomes a weak point insofar as it enables a Spearing the Sparrow attack.
By postponing the king's move, this strategy provided capacity of resistance against Spearing the Sparrow.
With the aim of exchanging pawns on the third file and so on, it was said that this strategy took over the main rationale behind the Morishita System and became a revival of its driving power.
While Gōda's R-38 variation was being played, Kōichi Fukaura started research on the conventional Morishita System resulting in postponing the king's move to K-88 against Spearing the Sparrow, by moving the silver to S-46, and then P-55, Px55, Sx55, hence building the position from the fifth file, which was found effective and made the Morishita System become popular once again.
