While it's certainly interesting to read about this sort of thing - and I'm interesting in all the computer history - it's worth pointing out that some very large percentage of all computer systems, from every country and every era failed.
So it would be a mistake to read too much into this project being Japanese, or indeed criticize their goals and failures. Like all of their contemporaries they boldly went where no-one had gone before, and like the vast majority of their contemporaries (and most everyone since) discovered limitations in both the technology of the day, and their own abilities.
The important thing is not that they failed. The important thing is that they tried.
