I found a couple of videos by Shakotanbugi on the Auto park festival AkaFes2012 on Awaji Island.
Not too many zokusha showed up, but this beautifully flared Cresta GX61 did!
Riveted flares, chin spoiler, side lightning takeyari, deep dished Mk IIIs, you name it and it has got it. 
Another interesting one is this video about a VIP Infiniti Q45:
I know: it is not a zokusha, but given the mods, fins and impressiveness it could easily be considered one. In Japan the Infiniti Q45 is called the Cima Y33, but the poster of the video must have thought Infiniti Q45 sounded a lot more impressive.
