Final answer:
The statement about Japanese negotiation positioning is not definitively true or false without context; Japan's approach to international negotiations has varied historically.
Step-by-step explanation:
The statement that The Japanese are often located in the middle of the scale on every dimension of negotiation is not clearly true or false without more context. Negotiation styles can vary widely, and it's challenging to generalize an entire nation or its representatives in such a manner. Historical context shows that Japan's interactions and positions in international negotiations have been influenced by various factors including geopolitics, economic interests, and national pride.
For instance, during the Treaty of Versailles and the Washington Naval Conference, Japan felt that it was unfairly treated by Western powers. On another hand, Japan's colonial activities in China showed a more assertive and dominant approach. Therefore, characterizing Japan's position on a 'middle scale' of negotiation dimensions requires examination of specific situations and time periods.
