Chicago Business Pulse
- Culture Practical, hardworking, and friendly. A major hub for logistics, finance, and manufacturing.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip Best times for calls are 9:00 AM to 11:30 AM. Chicagoans are known for being practical and direct but also friendlier than their East Coast counterparts. The Central Time Zone is the "Goldilocks zone" for North American business, allowing for easy syncs with both NYC and LA.
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.
