There’s another japanese
There’s another japanese cyberpunk classic I’d recommend, though it’s not dealing with cyborgs or transhumanism or anything like that, but as you liked the anarchic/madness aspects of those I think it might work – the 1982 Sogo Ishii film "Burst City" (who also directed the Einstürzende Neubauten short film Halber Mensch), which focuses on a group of punk rockers and biker gangs squatting some abandoned buildings outside Tokyo, which are to be demolished to make room for a new nuclear power plant. The main characters are played by actual prominent japanese punk musicians from that time, most notably The Stalin which I think is still one of the most well known punk groups in Japan today. There are lots of musical interludes by the groups, wonderfully crazy editing and great low life punks versus high tech cyber cops battles.
The movie was re-released on DVD in the west just a few years ago, so it’s not that hard to come by anymore
