How conservative the Japanese people really is? And the government?

This is a very vague question. But considering the asker’s comment on Mr. Nakajima’s answer, your interest seems to be in sex-related matters (I don’t think it’s the only indicator of conservative/ progressive, though).

Visual-kei

“None of my business” is the common attitude.

What are you struggling with in your life? What would you like to have instead?

It’s very common for a girl/ woman to ask a boy/ man to be her boyfriend.

They were very similar to the bromance of today but accompanied by sexual intercourse.

We don’t instantly tie it with sex when a father and his very young daughter are taking a bath together.

What has been your best sexual experience?

In the old era, gay relationships were very common and were even praised among the privileged social classes, such as Samurai and monks.

They don’t tease or beat up cross-dressed people on the road.

Moreover, buff guys are often avoided for their narcissism.

Why is squid ink safe to eat, while skunk spray is not? What makes the two liquids different from each other?

They don’t have the value that “guys must be macho.”

Yaoi

They don’t have the so-called “couple culture” seen in many Western countries.

What is the sluttiest thing your wife has ever done?

I sometimes feel people from the West are obsessed with those “gender” and “sex” things too much. Let’s think about something else sometimes. It’s unhealthy.

They don’t bring around their mates everywhere, which means they don’t worry about being single, gay, or whatever because no one cares about whom others are having/ not having sex with.

How do you see these below?

What is unattractive about a nice guy? Why do some women don’t choose nice guys?

I’ve heard it’s always the male side that is expected to take a move in some countries. It’s not the case in Japan.
