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.
Shanghai Business Pulse
- Culture Highly competitive and fast-paced. Business is often conducted with a mix of modern efficiency and traditional "Guanxi" (relationships).
- Lunch Break 12:00 PM - 1:00 PM (Nap time is common).
- Pro Tip Respect the 12-1 PM lunch and rest window; lights are often dimmed in offices for naps. The best time to call is between 2:00 PM and 4:30 PM. Avoid calling during major public holidays like Golden Week or Lunar New Year, as business comes to a complete halt.
