> but what is truly barbaric is the social taboo on strolling through a park on a nice autumn day sipping your coffee!

Wait, what? Has anyone ever said anything to you when you strolled around a park drinking coffee? I've been in Japan over 10 years and do that all the time, no one has given a shit about it. The only time I ever hear about these "taboos" is when foreigners try to tell other foreigners how they should behave in Japan, like it has some mystique about it or something.
