Kasuga? If so, one of the best 70s/80s Japanese manufacturers by a long, long way.
On topic, I used to make a few quid buying old guitars & basses for pennies, tidying them up & selling them on. In 2003 or thereabouts, I picked this up for £60, thinking I'd hose it down & maybe flip it for £150 or so. Tuned it up & it was the best-playing bass I'd ever had in my hands, bar none. Still is.
It's had a few upgrades & a bit of bling over the years but still probably only owes me £120 or so, all in. It's the one I'd save in a fire - you can stuff your four-figure basses.
