I know I'm late to the discussion, but I felt the need to chime in about Koga's intervention between Aya and Ono.
For context I watched something that was in regards to US and Japan differences in website design philosophy and how the cultural quirks define how things are designed, including food menus. To further explain how the different cultures figure out how to design these things the person talked about low-context and high-context cultures. In low-context cultures, for example if you have a noisy neighbor making noise at night you'd directly confront them, knocking on door or the such, and say "Hey, could you keep the noise down at night?". In a high-context culture, for the same complaint, you'd say to your neighbor in passing, possibly an accidental meeting in public or the like, something like "You have a good choice of music".
Because Japanese is a high-context culture Koga's question was perfectly fitting with how they go about these kinds of things. Tell the person in a way that isn't directly confronting them about the issue.
