This is interesting, but not great Japan advice. I just went and had a blast and did the opposite of his advice. I think people are different and want different things and don't feel bad if you just want to see the standard Japan checklist. His talk of everyone being surly..you know what, be respectful, everyone in Japan is so polite and nice that you will be happy with the level of service everywhere.
I've been many times and there is a time to venture out and there is a time to enjoy what everyone enjoys and both are fine.
