Osaka Business Pulse
- Culture Slightly more pragmatic and direct than Tokyo. Known for a entrepreneurial spirit and "Kuidaore" (eat until you drop).
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best times for calls are 10:00 AM - 11:30 AM and 2:00 PM - 4:30 PM. Osakans are known for being slightly more informal and direct than people in Tokyo, but standard Japanese business etiquette (punctuality, politeness) still applies strictly. Avoid the 12-1 PM lunch hour.
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.
