San Diego Business Pulse
- Culture Professional, casual, and focused on biotech and innovation.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Best reached between 10:00 AM and 4:00 PM. Like much of the US West Coast, the culture is casual-professional. Biotech and defense are major industries; expect technical competence to be highly valued. Punctuality is respected, even in a more relaxed atmosphere.
Tokyo Business Pulse
- Culture Consensus-based and very formal. Respect for hierarchy and "Meishi KΕkan" (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.
