Organisations that have contributed to NetBSD: Brains Corporation
Brains Corporation is based in Tokyo, Japan, setup in 1985.
Brains financed a port of NetBSD 1.3.1 to their Hitachi Super-H 3 based mmEye product, then very generously made their diffs publically available, and assisted with the importation of NetBSD/sh3 into the main NetBSD tree.
