Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
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.
