I met the imitation wheels salesman before. They buy a set of ori wheel, make mold and use cast alloy technology to produce the copies. If you see imitation wheel that has 'made in japan' wording, big % they are malaysia product (price about taiwan wheel or slightly cheaper). They also produce some wheel with japan, japan design, design in japan or etc wording (copy of taiwan wheel).
If you ask if it is ok to use, I can only tell you the risk is there but with today's technology, the wheels will not break so easy compare to the past. All those pics you can find from internet, 99% is either involved with serious road/track accident. In similar case, even ori japan wheel will break. I did saw a piece of genuine 18" G-Games 77 broken into 3 pieces after accident (laid on Monster Garage corridor in singapore few years back). If you concern about wheel bent after hitting pot holes, I can tell you even genuine japan forged aluminum wheel will bend too. The 18" Advan model 5 (forged, 8kg front 8.7kg rear) on my car have 1 wheel bent. My old wheels CR-Kai (not forged. 9.8kg each) also got 2 wheels bent. this thing really cannot avoid except you keep the car at home display only or drive 20-30km/h all the time.
If cost is concern, buy used ori factory car wheel that people trade in for aftermarket wheels. Normally will be cheaper than imitation. Those from new cars are the best deal. If want aftermarket design, then buy taiwan brand. My friend is tire shop owner, he himself also use taiwan wheel. He told me not worth to use new japan wheel.
