SPS Co., Ltd. (株式会社エス・ピー・エス; also written "S.P.S") was a company based in Fukushima, Japan, headed by Tomohisa Konno (今野智久). It was established in March 1982 [1] and is mostly remembered for its arcade ports for Sharp's X68000 home computer.

On July 27, 2005, NetVillage announced it had entered into an agreement to form an alliance with SPS to operate and develop online games. As part of this alliance, SPS would become a subsidiary of NetVillage. [2] This did not happen, however; instead, NetVillage formed a wholly-owned subsidiary called NVSOFT. As part of a "comprehensive agreement" between NVSOFT and SPS, SPS president Konno would serve as advisor to NVSOFT (which he did [3]) and a "new" staff (essentially SPS's old staff [4]) would "be hired at NVSOFT's newly established Fukushima branch, which [would] conduct software planning and development on a contract basis."

Prior to all of this, some SPS staff joined Sun-Tec. DigiCan was started by former staff in 2004. A Fukushima graphic design company called Kovax sometimes collaborated with SPS. Though the company wasn't started until 1989 [5], there are references to Kovax in SPS games from before then (Re Birth, The Return of Ishtar).

SPS went bankrupt in 2021. [6] Tomohisa Konno passed away on October 13. [7] SPS's back catalog was acquired that year by M2. [8]
