Hanoi Business Pulse

  • Culture Formal, hierarchical, and relationship-driven. Government presence is strong.
  • Lunch Break 12:00 PM - 1:30 PM.
  • Pro Tip Best reached between 9:00 AM and 11:30 AM. Business in the capital is more formal and hierarchical than in the south. Relationships with authority and government are often important. Trust must be built through multiple polite interactions and formal introductions.

Tokyo Business Pulse

  • Culture Consensus-based and very formal. Respect for hierarchy and "Meishi Kōkan" (business card exchange) are central.
  • Lunch Break Strictly 12:00 PM - 1:00 PM.
  • Pro Tip The most effective window is 10:00 AM to 11:30 AM. Avoid the strictly observed 12-1 PM lunch hour at all costs. Late afternoon calls (4 PM - 5:30 PM) are also acceptable, but ensure you follow formal protocols and hierarchy if multiple stakeholders are on the line.
