In Japan, taking a position—within a company, a team, a community, a relationship—brings obligations inherent in that position. You do not need to explicitly agree to these obligations; they come with the role. Being an employee creates duties to employer and colleagues beyond what any job description specifies. Being a customer creates obligations toward service providers.
Being a member of any group creates obligations to that group. This means that explicit agreements capture only part of what you are committing to. The full obligation structure includes what your position implies. Understanding what you have agreed to requires understanding what your role expects of you.
