It was named after an amateur player named Tateishi 立石. However, the opening has been used by professional players as well as amateurs. Tateishi received the
Special Kōzō Masuda Award in 2004 as a recognition to its development.

formation, and then push the vanguard pawn with P-75, and then P-65. From there the rook can move to R-66 and then R-76, so in the end it often settles into an
Ishida opening.
From the opening, the major pieces (rook and bishop) can move a lot, but since the bishops can be exchanged at any point, with such a formation the side playing Ishida will end up with golds and silvers being separated. Nevertheless, since often the golds and silvers in the Static Rook side's formation would lean towards one side (particularly when aiming at Static Rook Anaguma), the other side can aim for a rook exchange on the Static Rook's unprepared gaps.
This opening attracted attention as a countermeasure for
Static Rook Anaguma, and was played by many Ranging Rook professional players. In particular, shogi player Kenji Kobayashi researched the system as combined with his own "Super Fourth File Rook," in which came to be called "Super Tateishi," and which allowed him to win the Speed Shogi Tournament of 1994.
As a result of the developments in Static Rook countermeasures like moving a gold on the first rank, the Tateishi opening has become progressively rare among professional players.
