St Louis Business Pulse

  • Culture Midwestern values of friendliness and hard work. Business is professional but often involves personal connection.
  • Lunch Break Typically 12:00 PM - 1:00 PM.
  • Pro Tip Operating in Central Time (CST/CDT), St Louis is a perfect bridge for coast-to-coast US calls. Reach out between 9:00 AM and 11:00 AM for the most engaged responses. A friendly, personal opening is culturally expected before diving into technical or business details.

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.
