Synchronization Context

Syncing between Tehran and Tokyo is challenging due to the 5 hours 30 minutes offset. Teams should prioritize asynchronous communication or specific 'handover' windows.

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.

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.
