Tehran Business Pulse

Culture Relationship-heavy and formal. Respect for hierarchy is paramount.
Lunch Break 1:00 PM - 2:00 PM.
Pro Tip The work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.

Yokohama Business Pulse

Culture Professional, industrial, and closely linked to Tokyo. Values long-term corporate stability.
Lunch Break 12:00 PM - 1:00 PM.
Pro Tip Ideal window is 10:00 AM to 11:30 AM. As Japan's largest port, business is practical and trade-oriented. Standard Japanese etiquette (punctuality, politeness, formal protocol) is strictly followed. Avoid the 12-1 PM lunch hour at all costs.
