Logical discussion

Generally speaking, Japanese is not so good at logical discussion. Compared to before, it is getting better, though. One of the reason why Japanese skill on logical discussion is weaker than American is how much the training for debating in school age was. Recently, some school in Japan has started to have the debate class.
The traditional Japanese culture says “Silence is golden”. This is also one of the barriers to level up for the logical discussion.
