What Japanese etiquette nuances matter for a long-term partnership?

[Chloe_S]

I've just been assigned to manage a long-term project with a key partner team based in Japan, and while I've worked with international colleagues before, I know this collaboration will require a deeper understanding of formal business etiquette to build trust and avoid unintentional offense. I'm familiar with basics like bowing and exchanging business cards, but I'm concerned about the nuances of communication styles, decision-making hierarchies, and giving feedback in a way that is respectful and effective. For professionals with experience in Japanese business culture, what are the most critical aspects of cross-cultural etiquette I should focus on beyond the obvious formalities? I'm particularly interested in how to navigate silent periods in meetings, the appropriate way to express disagreement or concern, and how relationship-building outside of work hours differs from practices in Western corporate environments.
