Washington D.C. Business Pulse
- Culture Highly formal, networking-heavy, and influenced by government and policy.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Ideal call window is 10:00 AM to 11:30 AM and 2:00 PM to 4:00 PM. Punctuality is non-negotiable. DC is a "Power City"; be prepared for very formal protocols and the use of professional or political titles. Networking is a 24/7 activity here, but business calls should stay within 9-6.
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.
