In Japanese business culture there is a concept known as ma (間). Ma is the use of meaningful silence, pausing, and intentional empty space. It is an active part of the conversation that does not use words. When a member of the meeting raises a point or asks a question, the common response is to wait in silence until a senior member speaks. The pause in verbal communication is used so members can take time to fully formulate a response. It is a sign of respect to take time to think about a colleague's remarks. Addressing a comment too quickly, instead of waiting for a senior member, is perceived as impatience and brash. One must become comfortable with the flow of silence in a meeting and observant of other members' subtle actions.
Hierarchy is emphasized throughout Japanese culture and when it comes to formal business meetings, seating arrangements are intentional. There are two main concepts that set parameters for seating, kamiza (上座) and shimoza (下座). Kamiza is the seat or honor where the highest ranking member from the guest company sits. The seat is placed furthest from the door. Shimoza is the seat closest to the door, where the lowest ranking member sits. The member who sits in these seats is often sent to fetch items and complete other tasks. It is important that you never assume what seat you sit in. One should wait until the host guides each member to a seat. Each side of the table will be ordered from highest ranking member to lowest ranking member. The two ranking members will sit across from each other.
Decision-making in Japanese meetings is a group activity that usually occurs before the meeting takes place. Both businesses will internally discuss with colleagues and come to a decision. During the formal meeting these ideas will be documented and discussed opposed to creating everything from scratch. Instead of trying to introduce new ideas, you as a member of the meeting should provide support to your colleagues. This practice is called nemawashi (根回し).
