- Lunch Break12:00 PM - 1:00 PM.
- Pro TipBest 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.
Seoul Business Pulse
- CultureExtremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
