The thing with bass, especially in modern forms of dance music, and the sample shown here is that its not just about understanding the synthesis, yes sure that is the base for the sound but its only one step in the process, theres still the FX chain -> EQing -> Distortion -> Compresssion etc that gives it that unique characteristic you are after.
Any way I wouldnt know how to do this exactly how Yoji does it but you probably will be a bit further by trying, saw wave(s)(synced if more than 1), Low pass filter - (with the cutoff not too low- set to taste) set filter and amp envelope to taste. It sounds like this one has a longer decay and sustain (generally with bass patches i like to have a fast attack and release with a slower/longer decay and sustain) Some EQ and distortion (Yojis sounds like hes got some heavy overdrive running on that bass) with some compression and maybe you will be half there? hope this guide line points you in some direction
the sound of this bass does remind me abit of the spectrasonics trilogy
