NKS was the name of a leaf shutter mounted on some Japanese cameras of the 1950s. Various Japanese sources indicate (for example this page by K.Fukushi or this page at Japan Family Camera) that it was made by Nippon Kōsokki Kōgyō K.K. (日本光測機工業株式会社), that also made the Taron cameras.
The usual NKS shutter has B, 1–200 speeds. According to a post by someone who dismantled one, it is a copy of the Prontor II. There is a variant called NKS-FB with B, 1–300 speeds, and another variant called NKS-SC.
On some wartime cameras there is a shutter with T, B, 1–200 speeds marked NKS-TOKIO, it is probably an early variant, and Tokio is probably an alternative writing for Tokyo. An NKS TOKYO marking has also been observed.
Here is an incomplete list of cameras equipped with a NKS shutter (it was not necessarily the only type of shutter available on these models):
